No speaker voice coil can handle the full power of a sine wave driving a amp to clipping. This is a poor test and does not happen even at the factory. A sine wave test is to drive the amp at full power into a resistive dummy load that is rated at over the amp full power spec and is fan cooled or water cooled. A speaker needs impulse signal so that it moved and is driven by the music and when the amp clips at the peak for milliseconds it will nor blow the voice coil. that is how music works and you can drive the sub all night like that at just under clipping which is pulsed and not a continuous full peak to peak sine wave. If you are going to release test / evaluation videos then please do it right to give a fair evaluation and not blame the manufacturer for a product that works on its own design correctly and you incorrectly demo it. i dont have any affiliation with Alto but i also dont destroy products with incorrect use i use KV2 Audio EX 2.2 subs. and 2 are enough for 500 people rooms. when positioned and used like the manufacturer intended.
don't be put off by any comments you may hear. Make no mistake these are awesome speakers. I have 2 x ts 310s an. d 2 x ts 212s subs and they sound fantastic. You will always get people who will put them down and i guarantee 90% of them would not know which was which if you blindfolded them including me. Are they on par with the qsc k series and similar, well when you take into account the price then yes they are. Do they sound as good, well to the trained ear probably not, but i cant remember the last time i did a disco and heard people discussing my mids, highs and lows, because nobody cares as long as they sound good and they do.
I upgraded to qsc from alto and was disappointed, 1 of my qsc tops was as much as the whole alto rig and for majority of small gigs it was unnecessary. The qsc shines outside and for live but for pre recorded music the altos sound amazing for what they are. Will add too my qsc’s would get stinky at clipping as well, you aren’t supposed clip powered speakers they should be treated as a external amp and passive speakers.
This is a pretty bad review from you man, ive got 2 of these subs and they are really good quality and value for money. They aren't made to be bashed at max gain on the back of the amp, mine has run for 2 years on its normal setting being played aggressively every weekend and not a single issue. You are just giving this speaker a bad with a negative opinion, you started the video being negative and it made it shit.

As soon as you slapped the cabinet I immediately said to myself “that didn’t sound good” real hollow sounding. Lots of cabinet resonance. I did not expect it to fail in minutes. That was surprising. Can you imagine being in your first gig with this box and having it fail like that with 50-100 ppl counting on you for a party? Wow
I use 4 of them and they have a solid sound. They are not so bad as you talk. They don't have that punch but you can definitely feel rumbling your bones and moving your clothes. The only missing thing (my opinion) is a better x-over function. It doesn't have 1000w RMS it does 500-600w but hey for the price you get it it's really good. If you combine it with 2 15" subs they will rock! I usually use them for techno/house events and I've never had any problems. 7/10
Great review and honest, I was surprised to see when you removed the woofer from the cabinet, to see the woofer was a single voice coil woofer, I was expecting to see a dual voice coil woofer, that's probably why you guy's where able to burn out the woofer so easily, I would still buy the (Alto TS-318S) sub woofer, just replace the bass driver with a better quality woofer. Thanks for the video!!
if you already own the sub i would agree but, If you don't spent that extra woofer money and get a true and tested sub like qsc..Rcf..jbl.. or yorkville..I learned the hard way..buy good the first time and you won't look back.
A bit of voice coil smell is pretty normal imho when the speakers get hot for the first couple times. It goes away over time. I own a lot of speakers that smelled significantly when driven hard for the first couple times. They still work great years later.
I remember the JBL PA we had in my old band. 2x SRX718s subs per side, had to run them really hard at times and they did smell a bit but never ever failed
i have my own 318s subs, 2 actually. And for me the bins is AMAZING. And i just don't understand why you push a 30Hz Sine wave through that bin. it was only made to go as low as 40Hz. 10 Hz does not sound a lot but pushing 30Hz at 90% of the power is not a great idea!!!! Overall the bass bins is fantastic end of story
Even most professional series subs aren’t designed/capable of reproducing 30hz at full volume. That’s where the +10db, -6db specs come into play. These are designed to sustain 44hz at full volume. At 30hz your just burning the coil out. Knowing what you’re doing, and how to properly use what you have is half the battle.
@George Snow I think its the other way around ,2 me it sounds that they,and you cannot admit that at this price range its actually amazing sub,so you can convince yourself that overpriced brands are worth the beefy price tag
@@littlecncshop you are correct... these "2 Dudes" are exactly what their name implies... they know nothing about professional sound and the science behind it... there is no music where a constant 30 hz sine wave is produced for long periods of time, so this "test" means nothing for real world use.
I trust that the amp does not have limiter. When amp is clipping, the amp is delivering DC current to the speaker and therefore roasting the voice coil. That is why never power a passive speaker with underpowered amplifier, you will burn the coil of the speaker.
Yep! Not only does the driver get fed DC at full power, maximizing resistive losses, but the voice coil stays still for longer instead of excursioning, reducing the heat exchange with the pole piece.
Did you run it to mic levels when running from your device? If you did thats the reason why the coil started burning. The amps used will always be rated to the speakers peak power. But it can only maintain peak for a few seconds.
I refuse to ever haul around 18" Subs. However, I purchased the original 41.5 lb Alto TSUB12 like 9 years ago. I just traded it in at Guitar Center towards a Harbinger MLS1000 array system and got $135 for the trade in, so it held it's value well over 9 years! I never had any problems with it. It was a boomy sounding sub though for a 12" Sub. I was only $299 New! I purchased a Alto TS212S Sub about 4 years ago. Much punchier sounding bass, and better, sleeker box. I never turn it up past Unity, and it has been a great little SUB that I use. I DJ weddings with 50 to maybe 200 guests tops, and mostly 50th, 60th, 70th birthday parties with under 100 guests. So I only use a single 12" Sub in my set up, and it's enough bass. I get often asked to turn the bass down lol.
I used one of these this past Saturday. I have a pair of QSC 12.2 but no sub... drummer had this Alto sub that he brought. I was scared to use it! The bassist told me they always crank it to the max. Against my better judgement, especially after watching this video, I cranked it. They were playing outdoors. This sub held it's own. I actually had to bring the kick drums down slightly. It wasn't a "slam you in the chest" type of bass, but it did fill the bottom end. I am not sure if I would buy one tho.
The chest thump is usually the upper end of the bass and the low end of the tops e.g. 80-120 hz. The rest is low bass down to the 30s that gives that satisfying ear pressure if it's loud enough.
May be you should have given it a gentle break in rather than thrashing it out of the box ? I don’t know 💁♂️ I’m still using the 215s they only sound good with certain types of music. To be honest I was disappointed inthem from the off .
@@damienlobb85 I wonder if DAS has a similar 18" driver to RCF/dB. On the RCF side, as a mobile DJ I'd consider replacing my KW181 with the new RCF SUB-9004-AS but it weighs in at 125lb compared to the ~90lb KW181, so I'd rather haul around the lighter KW181 even though I'd much rather have a more powerful 18".
@@djstacktrace I had seen a review on the EV ETX 18" in the review just like the Alto everything was good except the subwoofer itself. Dude dropped at Seismic Audio 18" in. He said power consumption went down a lot. Sound levels went up.
Try Indian products they will blow your mind. What you showed us was just a normal speaker with cheap class D amp with subwoofer crossover also the cabinate construction is bigger thats why it sounds horrible. Any way very good review really appreciated 😊
complimenti x i tuoi video molto interessanti ho comprato b&c 15tbx100 ho sostituito il cono e ti assicuro che e diventato molto più aggressivo e pulito grazie del tuo consiglio
Damn, I just brought the TS312S, now that you've done this review helps me out. Now I will upgrade the Subwoofer for sure and get that fill inside. What specs would you recommend for the Subwoofer?
I design hifi speaker and subwoofers and have had a lot of experience playing with box size and tuning. Likely the boomy sound is due to an undersized cabinet and so some fill might help. You could try to plug one of the ports with a towel and see how it sounds just as a test . That will lower the tuning frequency and add the one blocked port as more air volume in the cabinet. One things is with one port only at high volume you might get some port noise. Good luck!
I know of a few bands that use Alto stuff. Also I had one of the PA speakers from them but sold it. To be honest, if I had never heard the better stuff such as QSC, EV, JBL ... I probably would have made do with the Alto speaker. But test them side by side and Alto comes in last ... but it cost half of what the big names want. And as someone pointed out by feeding a 30hz signal, that sub was doomed. A sub that size should have gotten maybe a 60hz signal. In real life, 90% of the bass is above 50hz anyway ...
It's understandable that you believe the driver being doomed was natural but, at the same time, I, as a designer, think the necessary protections must be built into the amplifier in integrated products like these. The amplifier should not be able to fry the driver to destruction.
So for the record it might be a bad box. Just like the qsc I got DOA in the box. Sent it back and eventually was sent a new one and it works great. Shit happens. It's not the only speaker that's happened to. My friends macbook pro burned out after 15 minutes of use. We actually went to the apple store and they didn't even bother fixing it they just gave him another laptop. Again it's electronics and shit happens. Meanwhile i do have a very old sony laptop that i turned into a chromebook and still works great.
I want monster bass for my house dj set up would I be better off with one of these monsters or a krk 12? I’m thinking the krk would be clearer and more precise and this would be more powerful but crude ?? Thanks
Just brace the inside, 2 planks of wood as a cross will do it.... buy some white loft insulation and sprey glue it on..... build a bass reflex 2 shelf port and remove them 2 stupid carpet cardboard centers
Well, you playing sine wave at almost full tilt, what where you expecting? Do you even understand what clipping is? What shape the wave takes? Clipping can damage a speaker even when it’s bee underpowered. I like your reviews but you totally dropped the ball in this one
If that amp is a stable amp and killed the speaker is it a 4ohm or 8ohm class d amp rating I cannot find any info and alto acts like its top secret info
Ok so I have 2 Altos 15 power speakers plug in to stereo left and right on my yamaha mixer . I have another 12 inch power alto speaker . Question is how do I connect the 12 inch , to the mixer or to one of the speakers because I want to use it as a monitor speaker
If you was to put a better driver in it you feel it would help or work better within what ever the true rms amp is limited too? As some going cheap on ebay (pair) shame cheap stamped frame
Electro voice have a bypass system so The speaker not gets blown Down, and its working 100% good. but alto has at all, a largere bass port on all their subwoofers.
@@kevinwillson4297 I never use one before, only the 18 inches, but RCFs are pretty good because they produce good drivers and the amps are also good, so i would say yes.
It will definitely be 1000watts rms but either way thats not important as its mainly marketing tbh its the spl and quality of components and box design which makes a difference wattage is just the fuel the subwoofer runs on along with the magnet etc also its gotta slap hard but have minimal to zero distortion
If your on a budget check out bishopsounds subs ( maybe hard in the states? ) I replaced my ts312 sub with there 400w RMS jobby ( which was just for a laugh as it's only rated at under half the alto plate amp ) and it made a great improvement. There 18" subs are pretty impressive for the price as well. You can get either a 1000w RMS or 1500w RMS
That amplifier looks just too small for 2000W, even by Class-D standards. Maybe it smoked the heck out of the woofer's voice coil because it was clipping. Anyways... great vid. Cheers!

Zase jeden čo sa hrá na múdreho. Napojiť 30Hz z generátora a dať do na plný výkon bez akého kolvek chladenia ???!! T by zničilo aj ten najkvalitnejší menič. Takýmito neprofesionálnymi testami devastuješ značku výrobcu. To je na súdny proces. Ak to nevieš nerob radšej nič.
That is a blanket statement and is patently untrue..... many many professional speaker systems are switching to powered speakers. I am a professional Audio engineer and have been for many years (working and touring with very famous acts you will have heard of)..... There are many advantages to active (powered) speaker systems including but not limited to improved damping factor, reduced resistance due long speaker cable runs and the ability of the manufacturer to more closely match the amplification and system processing to the speaker components and enclosure characteristics, thus resulting in a more constant audio response from system to system. This allows system engineers to be more confident in the speaker systems they will be using in the field.
@@arthurton365 likewise I have a long history in both professional and domestic audio, what you have not understood is I am not talking about the ancillary equipment ( cables , connectors etc ) I am just talking about the stand alone quality of the speakers , I am well aware of the advantages of active speakers and in a professional sense they are ideal in terms of convenience . But in a real world sense not on the budgets used in professional circles a passive system gives you much better value for money both in build quality and performance for example an active spk costing $1000 will not give you the same performance in sonic performance, power output and build quality as an amplifier and passive speaker of the same value would, that may be different in the professional world when your spending hundreds of thousands of dollars but for normal , DJ work it is as I've said !
Frequency range is only 35 Hertz you better erase that video before you return it you said 30 Hertz ... Crossover should have caught it though.... Please put one of your own drivers in there see what we can get out of it.. thanks..
The sub is still fully functional. We wanted to test that frequency and to see what would happen for this exact reason. Unfortunately the subwoofer would have fully failed if we hadn't have turned it off right when we started to smell the coil. So unfortunately for anyone who buys this they should realize this could happen to them if they decide to push these sub for some real low frequencies
@@2DudesAudio I have the old trusonic 1200 18inch.. it's boomy also the cabinet is too big that's the only reason I was interested in the newer version....scary though.. 18 inch will be more boomy the anything smaller....I run everything through my driverack DSP little compression helps for punch.
They normally comes with a shit driver, i once load the old 18" sub with some fatial pro 1700watts, and they still running ok. You can upgrade them with a better driver.
Its not a pure SPL sub like you have in a car. To put that frequency through it without running it in is gonna fuck it up. Think its probably an unfair review. Your going for max spl on a system that's not designed to do that.
This guy need a larger vocabulary. All I keep hearing is I don't know. Let me guess. As a DJ who owns many subs. They do the Job. This guy does not know what he is doing. WOW 😳 This guy should title. How to burn your shit.
You know that this is the low end of pro audio then you will play constant 30 hz at 90 percent? like wtf if you're going to review subs tell us how it sounds then proceed with the toughness test. your standards are pretty high and youre obviously rich for doing this. and we're not sure if youre telling the truth because you didnt show the back while its playing. i dont see evidence that it failed and you mentioned at the comments its still working, so what now?
@George Snow how is this a bad product it was hit with a straight sine wave up to almost clipping you hit anything with a straight sine wave to clip and it will fail even overpriced qsc shit will fail
One of my dj friend own this......."things", it's clearly sound cheap, horrible and muddy as hell. he borrowed me this one one time ( i own a KS212c) and i regret because it sound more behind the sub than the front, limiter come up at the middle, LF extend saturated the sound a there´s clearly a huge delay between the sub and my K10.2, imagine i need to set the delay on my main loudspeakers to get a correct alignment. Avoid this horrible sub as possible and buy something serious.
Let us clarify some things since I see alot of the same question. We run a 30hz sine wave through all the powered subs we test. We know it's very tough on the units, we do this to torture test. Alot of edm, rap, and hip hop will reach 30hz and lower but I know that's not the same as a sine wave. Again we do this as a way to see just how tough the amp and driver combo are. Sorry for the Alto fans, we did not like this product.
2 Dudes Audio eventhough this level of subwoofer is at the lower end of the spectrum, just like any NEW driver in any enclosure it requires burn in as it will not behave to its full potential until that process takes place. Most drivers incur damage because users are either impatient to follow through with the burn in process or just plain ignorant of that particular fact. Yes the amplifier may may be over powered for good reason, particularly as it is amplifying low frequencies where headroom is often non existent but not properly understood and/or respected in this particular context hence it can damage the driver even after burn in, despite the limiting circuit. Anyway that’s another story. Overall this product seems to be great value and if utilised correctly and within its means, performance is quite admirable amongst its higher priced brethren, though obviously not at their level. Fair go...
there are almost NO PRO AUDIO SUBS on the market that will hit 30hz @ -3db, your lucky if you get -10db at 38db, only car and home audio/theater subs get deeper than 30 hz. . . however if for some reason i am wrong about what i said please point me in the right direct as to what pro subs play sub -38hz frequency at with -3db , I have been looking for years and from research only touring rigs do that ;9 also by the way if you a sub recieves a frequency below its port tuning frequency , the sub unloads and essential goes to being free air, at which point you will blow the sub , just as you almost did.
@@mikeriverajr4447 I understand what you mean, although you are just abit wrong about the whole 30hz deal. I've known plenty of pro audio subs capable of very loud 25-30hz notes. And you're right about the port tuning but I repeat "we do this to every sub we review" and this is the first to fail. So🤷♂️

Even most professional series subs aren’t designed/capable of reproducing 30hz at full volume. That’s where the +10db, -6db specs come into play. These are designed to sustain 44hz at full volume. At 30hz your just burning the coil out. Knowing what you’re doing, and how to properly use what you have is half the battle.
@George Snow I think its the other way around ,2 me it sounds that they,and you cannot admit that at this price range its actually amazing sub,so you can convince yourself that overpriced brands are worth the beefy price tag
@@littlecncshop you are correct... these "2 Dudes" are exactly what their name implies... they know nothing about professional sound and the science behind it... there is no music where a constant 30 hz sine wave is produced for long periods of time, so this "test" means nothing for real world use.
Keep up the good work! Love these teardowns!
Rudy Zuniga same
Nice work. It’d be interesting to connect a watt meter and see how much they are actually drawing.
150W, 200W tops?! That's where my money'd be at.
I trust that the amp does not have limiter. When amp is clipping, the amp is delivering DC current to the speaker and therefore roasting the voice coil. That is why never power a passive speaker with underpowered amplifier, you will burn the coil of the speaker.
Yep! Not only does the driver get fed DC at full power, maximizing resistive losses, but the voice coil stays still for longer instead of excursioning, reducing the heat exchange with the pole piece.
Did you run it to mic levels when running from your device? If you did thats the reason why the coil started burning. The amps used will always be rated to the speakers peak power. But it can only maintain peak for a few seconds.
I refuse to ever haul around 18" Subs. However, I purchased the original 41.5 lb Alto TSUB12 like 9 years ago. I just traded it in at Guitar Center towards a Harbinger MLS1000 array system and got $135 for the trade in, so it held it's value well over 9 years! I never had any problems with it. It was a boomy sounding sub though for a 12" Sub. I was only $299 New! I purchased a Alto TS212S Sub about 4 years ago. Much punchier sounding bass, and better, sleeker box. I never turn it up past Unity, and it has been a great little SUB that I use. I DJ weddings with 50 to maybe 200 guests tops, and mostly 50th, 60th, 70th birthday parties with under 100 guests. So I only use a single 12" Sub in my set up, and it's enough bass. I get often asked to turn the bass down lol.
Can you do a test with the new Alto TS18S? And the QSC Ks118?
I used one of these this past Saturday. I have a pair of QSC 12.2 but no sub... drummer had this Alto sub that he brought. I was scared to use it! The bassist told me they always crank it to the max. Against my better judgement, especially after watching this video, I cranked it. They were playing outdoors. This sub held it's own. I actually had to bring the kick drums down slightly. It wasn't a "slam you in the chest" type of bass, but it did fill the bottom end. I am not sure if I would buy one tho.
The chest thump is usually the upper end of the bass and the low end of the tops e.g. 80-120 hz. The rest is low bass down to the 30s that gives that satisfying ear pressure if it's loud enough.
what replacement sub woofer would you suggest to replace the stock one?
The driver or transducer is kinda familiar, oh look, its the same driver on the Behringer VP1800s...
Can you dudes test and tear down the EV ELX200-18SP. I always wondered how this entry-level sub performed?
Love your channel.
Rock On
Mine are great they rock and sound very clear and deep pounding bass
May be you should have given it a gentle break in rather than thrashing it out of the box ? I don’t know 💁♂️ I’m still using the 215s they only sound good with certain types of music.
To be honest I was disappointed inthem from the off .
He is an ignorant... Dislike
You should put the KW-181 driver in this box to see how the Alto amp holds up
The KW181 driver isn't anything special either, it has a 3in voice coil and is rated around 500w RMS.
@@damienlobb85 Which brand has a better driver at that price point?
@@djstacktrace Not many to be totally honest. dB technologies perhaps? They use RCF components.
@@damienlobb85 I wonder if DAS has a similar 18" driver to RCF/dB. On the RCF side, as a mobile DJ I'd consider replacing my KW181 with the new RCF SUB-9004-AS but it weighs in at 125lb compared to the ~90lb KW181, so I'd rather haul around the lighter KW181 even though I'd much rather have a more powerful 18".
@@djstacktrace I had seen a review on the EV ETX 18" in the review just like the Alto everything was good except the subwoofer itself. Dude dropped at Seismic Audio 18" in. He said power consumption went down a lot. Sound levels went up.
Thanks for your videos. Can you do a review of Db Tecnologies Sub? 612 or 615 or 618. Thanks
can u do one on the ALTO PROFESSIONAL TRUESONIC TS18S
Try Indian products they will blow your mind.
What you showed us was just a normal speaker with cheap class D amp with subwoofer crossover also the cabinate construction is bigger thats why it sounds horrible.
Any way very good review really appreciated 😊
complimenti x i tuoi video molto interessanti ho comprato b&c 15tbx100 ho sostituito il cono e ti assicuro che e diventato molto più aggressivo e pulito grazie del tuo consiglio
Can you check out the blastking 18in power sub teardown.
Damn, I just brought the TS312S, now that you've done this review helps me out. Now I will upgrade the Subwoofer for sure and get that fill inside. What specs would you recommend for the Subwoofer?
I design hifi speaker and subwoofers and have had a lot of experience playing with box size and tuning. Likely the boomy sound is due to an undersized cabinet and so some fill might help. You could try to plug one of the ports with a towel and see how it sounds just as a test . That will lower the tuning frequency and add the one blocked port as more air volume in the cabinet. One things is with one port only at high volume you might get some port noise. Good luck!
Entry level sub. Can’t expect much out of it
I know of a few bands that use Alto stuff. Also I had one of the PA speakers from them but sold it. To be honest, if I had never heard the better stuff such as QSC, EV, JBL ... I probably would have made do with the Alto speaker. But test them side by side and Alto comes in last ... but it cost half of what the big names want.
And as someone pointed out by feeding a 30hz signal, that sub was doomed. A sub that size should have gotten maybe a 60hz signal. In real life, 90% of the bass is above 50hz anyway ...
It's understandable that you believe the driver being doomed was natural but, at the same time, I, as a designer, think the necessary protections must be built into the amplifier in integrated products like these. The amplifier should not be able to fry the driver to destruction.
What are the chances of you guys reviewing the new Alto TS18 and Harbinger VS18? Looking to buy a sub to go with the EV ZLX15's I just bought.
I might have considered these Alto 18" subs if they were made from light weight plywood. 86 pounds is too heavy using particle board.
So for the record it might be a bad box. Just like the qsc I got DOA in the box. Sent it back and eventually was sent a new one and it works great. Shit happens. It's not the only speaker that's happened to. My friends macbook pro burned out after 15 minutes of use. We actually went to the apple store and they didn't even bother fixing it they just gave him another laptop. Again it's electronics and shit happens. Meanwhile i do have a very old sony laptop that i turned into a chromebook and still works great.
I want monster bass for my house dj set up would I be better off with one of these monsters or a krk 12? I’m thinking the krk would be clearer and more precise and this would be more powerful but crude ?? Thanks
sorry but, polyfill cannot damp or work at those frequency , since the wavelength is much longer than 1 m
Poly fill and a heavy duty sub woofer will make it a winner. The construction of the cabinet and coating is nice.
Just brace the inside, 2 planks of wood as a cross will do it.... buy some white loft insulation and sprey glue it on..... build a bass reflex 2 shelf port and remove them 2 stupid carpet cardboard centers
Playing long continuous notes at tuning and max volume is a good way to blow speakers.
So if an alto owner blew the driver on this sub, What replacement driver do you recommend to match up with the amp.
you could get a Peavey black widow sub or one of the eminence subs but match the specs
Well, you playing sine wave at almost full tilt, what where you expecting? Do you even understand what clipping is? What shape the wave takes? Clipping can damage a speaker even when it’s bee underpowered. I like your reviews but you totally dropped the ball in this one
i like to see whats inside of that monster. thank you sir
If that amp is a stable amp and killed the speaker is it a 4ohm or 8ohm class d amp rating I cannot find any info and alto acts like its top secret info
ts18s or behringer B1800XP???
Ok so I have 2 Altos 15 power speakers plug in to stereo left and right on my yamaha mixer . I have another 12 inch power alto speaker . Question is how do I connect the 12 inch , to the mixer or to one of the speakers because I want to use it as a monitor speaker

would like to see you guys do a review on the Soundboks speaker
If you was to put a better driver in it you feel it would help or work better within what ever the true rms amp is limited too? As some going cheap on ebay (pair) shame cheap stamped frame
Guess work on the rear buttons and blows it upon first use...good review
is it ok if you replace the speaker with a 6inches voice coil , ?
You should test the behringer b1800xp.
yes please!
same shity woofer i have replaced of whit rcf
Oh wow it's the same one i saw and sound tested at Guitar Center a month ago
I have this sub. I need to replace the woofer, where can i find a replacement speaker? What ohm is the speaker?
It might be the two huge ports. Maybe bigger isn't better?
so do you know what is the actual power rating of that driver? 500 rms ? and what is the actual SPL , cuz it cant be 133
@@mikelachendro488 cool 😊 cant wait to watch it
Could you do a teardown of the electro voice ekx 18sp
Roberto i got 4 ev etx they work great to me
They definitely cheaped out on the driver, shame. In Europe here we have thomann, there is not beating there quality to price ratio.
Lotta hate....this is an honest opinion people...chill out.
so save some money, and slap a good woofer in there and you're in business!
Electro voice have a bypass system so The speaker not gets blown Down, and its working 100% good. but alto has at all, a largere bass port on all their subwoofers.
also the design of the box is a common and simple
You cant loose from RCF Subs🔊💯
Hey does the 15 in rcf sub do a good job
@@kevinwillson4297 I never use one before, only the 18 inches, but RCFs are pretty good because they produce good drivers and the amps are also good, so i would say yes.
It will definitely be 1000watts rms but either way thats not important as its mainly marketing tbh its the spl and quality of components and box design which makes a difference wattage is just the fuel the subwoofer runs on along with the magnet etc also its gotta slap hard but have minimal to zero distortion
could you demo mackie new drm 18'', would love too hear those .
What do you recommend buying to upgrade the sub in the alto ts318s i have two and want to put new subs in them and also audio fill
Theres alot of great choices, youd have to match the drivers parameters to alto's box tuning and dimensions.
If your on a budget check out bishopsounds subs ( maybe hard in the states? ) I replaced my ts312 sub with there 400w RMS jobby ( which was just for a laugh as it's only rated at under half the alto plate amp ) and it made a great improvement. There 18" subs are pretty impressive for the price as well. You can get either a 1000w RMS or 1500w RMS
That amplifier looks just too small for 2000W, even by Class-D standards. Maybe it smoked the heck out of the woofer's voice coil because it was clipping.
Anyways... great vid. Cheers!
Oie but i dont see any other videos of yours where u do the same to any other powered sub
QSC 181 sub video we did, sine wave was playing while I held it. It was doing a sweep just like in this vid. Every 30 or so seconds it goes up 5 hz.
Guess the only difference between vids was we took it out of box in QSC vid so it was free airing.
Just bought one used, i never go over 1/2 limit, dont push my subs beyond so i should be good to go. I had two EV ELX 118s that i loved.
How do they compare with the ev?

Hi man I have blown up both my alto Ts315 and ts218s when in used for a drum and bass party.

im good im sticking to my behringer b1800d pro
can i use this with a Bose S1 Pro?
hi, was the amp hot as well as the coil ?
Zase jeden čo sa hrá na múdreho. Napojiť 30Hz z generátora a dať do na plný výkon bez akého kolvek chladenia ???!! T by zničilo aj ten najkvalitnejší menič. Takýmito neprofesionálnymi testami devastuješ značku výrobcu. To je na súdny proces. Ak to nevieš nerob radšej nič.
There are no active speakers that have drive units on a par with their passive counterparts, active speakers have convenience value not much else !
That is a blanket statement and is patently untrue..... many many professional speaker systems are switching to powered speakers. I am a professional Audio engineer and have been for many years (working and touring with very famous acts you will have heard of)..... There are many advantages to active (powered) speaker systems including but not limited to improved damping factor, reduced resistance due long speaker cable runs and the ability of the manufacturer to more closely match the amplification and system processing to the speaker components and enclosure characteristics, thus resulting in a more constant audio response from system to system. This allows system engineers to be more confident in the speaker systems they will be using in the field.
@@arthurton365 likewise I have a long history in both professional and domestic audio, what you have not understood is I am not talking about the ancillary equipment ( cables , connectors etc ) I am just talking about the stand alone quality of the speakers , I am well aware of the advantages of active speakers and in a professional sense they are ideal in terms of convenience . But in a real world sense not on the budgets used in professional circles a passive system gives you much better value for money both in build quality and performance for example an active spk costing $1000 will not give you the same performance in sonic performance, power output and build quality as an amplifier and passive speaker of the same value would, that may be different in the professional world when your spending hundreds of thousands of dollars but for normal , DJ work it is as I've said !
Good passive stuff is $$$$. You need to factor in processing too. .need limiter....but you do you....carry that big amp rack.
please review cerwin vega cve 18 or cvx21
Frequency range is only 35 Hertz you better erase that video before you return it you said 30 Hertz ... Crossover should have caught it though.... Please put one of your own drivers in there see what we can get out of it.. thanks..
The sub is still fully functional. We wanted to test that frequency and to see what would happen for this exact reason. Unfortunately the subwoofer would have fully failed if we hadn't have turned it off right when we started to smell the coil. So unfortunately for anyone who buys this they should realize this could happen to them if they decide to push these sub for some real low frequencies
@@2DudesAudio I have the old trusonic 1200 18inch.. it's boomy also the cabinet is too big that's the only reason I was interested in the newer version....scary though..
18 inch will be more boomy the anything smaller....I run everything through my driverack DSP little compression helps for punch.
Is this a 4 ohm subwoofer or 8ohm..

BRUTÁL BASS SOUND !!!!!!!!!! 👌👌👌👌👌👌👌👌👌👍👍👍👍👍👍👍👍👍👍👍
Why would you drive a sinewave to clipping. A sine wave rating for a speaker is lower than the RMS rating. You just fried it.
They normally comes with a shit driver, i once load the old 18" sub with some fatial pro 1700watts, and they still running ok. You can upgrade them with a better driver.
If you had a little more enthusiasm your videos would be great bro
I'm abit monotone sorry I try not to be🤣
Since we didnt really "review" this subwoofer due to driver failure the title was changed.👍
Its not a pure SPL sub like you have in a car. To put that frequency through it without running it in is gonna fuck it up. Think its probably an unfair review. Your going for max spl on a system that's not designed to do that.
How about testing with a QSC subwoofer? I like it if you want to try it that way too!
We did, the part where I was holding it was a sine wave!
@@2DudesAudio but how was it heard in that sub box?

nice review broda :)
I wouldn’t trust alto. The quality is not really good. I’ll rather go with turbosound if that’s the case for cheaper price
cheaper price? 800/1000$ is cheaper than 600?
Can y’all do an eon 618
You know that this is the low end of pro audio then you will play constant 30 hz at 90 percent? like wtf if you're going to review subs tell us how it sounds then proceed with the toughness test. your standards are pretty high and youre obviously rich for doing this. and we're not sure if youre telling the truth because you didnt show the back while its playing. i dont see evidence that it failed and you mentioned at the comments its still working, so what now?
Read our channel description, it's what we do.
@George Snow how is this a bad product it was hit with a straight sine wave up to almost clipping you hit anything with a straight sine wave to clip and it will fail even overpriced qsc shit will fail
You know bum's where that shirt you are wearing
Good video 👍 saved me from buying this brand...I will stick to yamaha or turbosound...😁!
Hi dudes, is this a 8ohm or 4ohm LF driver
I think 8 ohm. But not sure
What is the size of the coil in that sub?
Not sure, Altos site may have that info, if I had to guess maybe a 3 inch coil
3"
One of my dj friend own this......."things", it's clearly sound cheap, horrible and muddy as hell.
he borrowed me this one one time ( i own a KS212c) and i regret because it sound more behind the sub than the front, limiter come up at the middle, LF extend saturated the sound a there´s clearly a huge delay between the sub and my K10.2, imagine i need to set the delay on my main loudspeakers to get a correct alignment.
Avoid this horrible sub as possible and buy something serious.
Let us clarify some things since I see alot of the same question. We run a 30hz sine wave through all the powered subs we test. We know it's very tough on the units, we do this to torture test. Alot of edm, rap, and hip hop will reach 30hz and lower but I know that's not the same as a sine wave. Again we do this as a way to see just how tough the amp and driver combo are. Sorry for the Alto fans, we did not like this product.
2 Dudes Audio eventhough this level of subwoofer is at the lower end of the spectrum, just like any NEW driver in any enclosure it requires burn in as it will not behave to its full potential until that process takes place. Most drivers incur damage because users are either impatient to follow through with the burn in process or just plain ignorant of that particular fact.
Yes the amplifier may may be over powered for good reason, particularly as it is amplifying low frequencies where headroom is often non existent but not properly understood and/or respected in this particular context hence it can damage the driver even after burn in, despite the limiting circuit. Anyway that’s another story.
Overall this product seems to be great value and if utilised correctly and within its means, performance is quite admirable amongst its higher priced brethren, though obviously not at their level. Fair go...
there are almost NO PRO AUDIO SUBS on the market that will hit 30hz @ -3db, your lucky if you get -10db at 38db, only car and home audio/theater subs get deeper than 30 hz. . . however if for some reason i am wrong about what i said please point me in the right direct as to what pro subs play sub -38hz frequency at with -3db , I have been looking for years and from research only touring rigs do that ;9 also by the way if you a sub recieves a frequency below its port tuning frequency , the sub unloads and essential goes to being free air, at which point you will blow the sub , just as you almost did.
@@mikeriverajr4447 I understand what you mean, although you are just abit wrong about the whole 30hz deal. I've known plenty of pro audio subs capable of very loud 25-30hz notes. And you're right about the port tuning but I repeat "we do this to every sub we review" and this is the first to fail. So🤷♂️
