- Quite an in depth one for you guys this time! Started off breaking in the GZPW9910 a bit further, and noticed an inconsistency with the dayton DATS software. So i took you guys though what I discovered!
Nice
My Stoner Mind Hi dad
Hi my stoner mind
Amazing subs. Can't believe the power of that amp from such a small size.
RWL2012 Yeah not to bad mate. Oh no really.
class D probably, it wont do that power at 100% duty cycle at all. but thats typical of almost all car audio amps
@@smallenginedude71 It IS class "D", and it actually will! Switch mode amplifiers don't dissipate nearly as much heat as an analogue amplifier, so it doesn't need to be built into nearly as large of a heat sink.
Class "D" switch mode amplifiers don't need to be nearly as big, because they don't dissipate nearly as much heat as analogue amps do. That allows them to produce 10 X the power, in a heat sink 1/2 the size.
Drums and Bass! If I lived in your country we would be friends. Nice video man!
When using added mass method, the Fs should decrease by about 25%. If its more or less you may get inaccurate measurements
This guy is an audio king😎😎😎 If the world ends this will be the guy in the desert trading electronic parts for food like in Star Wars 🤣🤣🤣🤣🤣
0:04 Did the door seriously clip his mic?
Carson Folio I noticed that too.
lmfao it did
Carson Folio what's that mean?
Holy it means the mic cant handle it so it plays back as distortion
well bass heads turn up there mics gain because people like to hear distortion because they think its how much bass something has.
You must have a magical home theatre system... Loooooove that bass.
Damn that is one high BL those woofers are crazy efficient
The inconsistency is not with the software. The added mass method works under specific criteria. First---you cannot just add mass and plop it down on the cone. It must be secured otherwise it can bounce around on it's own because it's not physically part of the moving parts. Double sided foam tape works great because it's very tacky, and it does not add significant mass on it's own. This absolutely needs to be addressed otherwise you're just shooting yourself in the foot/chasing your own tail.
Second----the added mass *cannot* be arbitrary. The premise of the added mass method is to cause the Fs to shift downward approximately 25%. This means for "typical" woofers, you usually end up adding 60-75% of the Mmd is. This may not apply to your case because you do not have "typical" woofers. Of course you might not know the Mmd before hand, but you can reasonably attain a good value, by *securely* adding mass, and then taking "dummy measurements" only to check the downward shift of Fs. Since your unloaded Fs is 65Hz, a 25% drop is 65Hz x 0.75 = about 48Hz. You don't want to add too much mass because then the spider's compliance will be too much different from it's at-rest state. Once you get that ~25% drop in Fs, THEN: take off the added mass and get a new baseline reading (because you were taking a bunch of trial runs solely to check the Fs--the other T/S parameters will be wacky). Then add and secure the proper added mass and run the Vas measurement with the added mass method. This will be the most accurate Vas figure using the added mass method.
Also, you cannot simply weigh the soft parts and use that as Mmd, because the outer portions of the surround and spider do not move as much as the inner portions, therefore their mass contributions to the *moving* system becomes more and more negligible the further away you get from the center of the system. With a heavy surround and thick, multiple spiders, this can account for quite some mass.
This is the cause of your headache. The BL changes because it's calculated based on the other raw parameter measurements/calculations. If the other raw parameters are wrong, nearly everything gets thrown off. Happy testing.
Congratulations. I think your answer is the best one.
Technically, they are in a box.... Just a big one. The room itself.
That would only be correct if the back side would be sealed from the front, thus (in)finite baffle
I would like to see these in a nice high compression front loaded horn box. These motors would be wasted on a ported box, they really need to be able to pressurize some air to get the most out of the tough little cones and big magnet motors.
I'm just thinking over this problem. Could it be that the added weight needs to be a significant portion of the cone+motor assembly. As in bigger woofer = more added weight needed.
I understand, that there is flux modulation of the magnet when the driver is run at 5,000 watts, but the BL rating suggests, that there could be as high as 2,080 Newtons of force from the voice coil. That can lift the weight of 3 people! Am I right? 5,000 watts puts 100 volts, which draws 50 amps RMS @ 2 Ohms. that's 70.7 amps peak, which, multiplied by 29.416 Newtons per amp, equals 2,080 Newtons. With flux modulation and flux saturation of the magnet, it could realistically be closer to 1/2 that. When you said you could sit on the cone, and barely flex it, that could actually be accurate. If I'm right, air loading will be less than 1% of the load on the amplifier. The coil can easily lift a 100 Kg person! The question, is weather the magnet has the field strength to maintain BL at 5,000 watts?
Late to the party here, but that little ripple in your impedance curve is probably a fan running (power supply/computer/etc.). Any wind or noise will give you a bad reading. Also you need to add a lot more mass on very stiff spl subs to get accurate Vas. I do about 3 pounds on something like those.
Hey bud, love your videos. I have 3 questions if you can answer when you get a chance. I just purchased 2 of the new 712 DVC2 redline subs. I have not installed them yet so do I need to break these in as well? I know their rms is 1200 but I know they’re underrated. How much power can I put on them without damaging them? Last question is are you going to do a video on just the new 3512i subs? Keep up the good work. Thanks.
YEEES! Loving these franken-subs!
When you attach your weight to the cone, how do you attach it? A thick adhesive putty?
I'm in Iasca over in the states and no one has ever clamped even 7k out of these bandas I want to see u clamp it !!
nice
Trying to match parameters closer to manufacturer specs is not good. They can be wrong to begin with. Three factors are at play here.1. Warm versus cool parts2. Weight placement on cone assembly.3. Connection joints to frame distribute some of the total mass of cone assembly. That is why you see a change in the compliance of the suspension, Qms.
i just got my DATS v3 system. i sure hope they worked out this bug
I got One 12 Inch Hertz spl show sx300d2 3200watts Peak at 1 Ohm in a Kenwood kac-9105d 1800watts at 1 Ohm Amp and my hole Home is flexing😂😂😂😂😂😂 thanx man learn much from you about subs and amps . Peace out from Germany bassheads over the world
I want to see them mounted
If that sundown sub is shit, I'll be happy to take it off your hands! Lol
Brandon miller its ground zero
I need a pair if that.
Dope
Vas is changing and its using that to cal.. Id mount the drivers in a baffel and keep the front and rear wave separated..
The TS parameters must be measured "without baffle". I think Oscar Sanchez Jr's answer is the best one.
I need two of these speakers their awesome
that sick bass
The problem with T/S parameters is that they only measure at tiny voltages, big subwoofers/speakers don't run at 1w or a single frequency.
Small signal parameters are a great way to see how a given driver will perform. Many factors impact large signal performance, but small signal still indicate overall characteristics. Not to mention, all speakers will and do play at 1watt.
ITs important and have enough weight on the cone when testing. do you get Error when you not have enough weight on the cone ?
nice vid, a bare vid, a true woofer luvers vlog
LOLOLOL 0:4 THE MIC ACTUALLY CLIPPED CAUSE OF THE DOOR xD
Banda audioparts from Brazil hehe
hopefully not 2 late just wondering how much should a dd m80 700rms push a dd 712 sub?
What kind of app do you use on your phone? I am looking for that😊
I bought subs and cabels and an amp for 22000 Swedish crowns i put it in hooked it up and get it set right then i played like it was old stuff. in my opinion its no need to break it in
that amp is also not a 9000 watt rms capable amplifier, or that setup. On there own page it lists the input current, at rated output, at 350A. 14v at 350 amps is only 4900 watts and that's peak not rms at 100 percent efficiency. Accounting for best efficiency rating of a class d amp of 90% and a best in class 90% efficient switching supply, and on top of that its rms not peak. At 9000 watts the amp and supply would need to source over 18000 watts peak. Not possible with that setup you have, those cables are way too small. RMS calc : 1.414*9000=15390 watts peak, 15390/14=1100 amps, smps eff.=1.10*15390=16929/14=1209 amps , class d amp eff. 1.1*16929=18621/14=1330amps. I don't think you got the correct numbers.
Do you not have anything better to do?
Banda list this as AVERAGE MUSIC PROGRAM. This means the value is taken over a 3 minute period while playing music. The stuff they listen to in Brazil is more trancey and clubby, making for pulses and gaps in the bass, lowering the average. Feel free to email banda yourself to confirm this. Playing a continuous sine I have clamped rated power from these in a vehicle on static 1ohm dummy loads drawing over 850a. Also, if you had ever looked inside of of these amps, you'll notice that the components inside and rail voltage are fully capable of rated power.
Are there any online dealers for digital designs subwoofers in the us
r u selling that sundown sub
Maybe. Its a Team 15". You UK?
no im us
i really need a bigger sub i have a set up and u gave me the confidence to but a car system in my house I have a 100.1se infinity 10inch a 300 watt Linwood and a 450 watt power supply
kenwood
barevids do u have a facebook
HOW MUCH WOULD YOU SELL THEM FOR ??💰💰 on hand ??
Have u seen the Russian built subs called pride? If so what do u think? If not check them out!
Mike Parker Have you seen Steve Meade stand on one while playing and no damage was done amazing subs
how would bass be affected by the vacum of space. i.e. Decaf Astras car sittn on the moon jamming
Sound relies on pressure waves; if you're in a vacuum, there's no substance for those soundwaves to pressurize. This is why space doesn't have sound. Although it's not a true 100% vacuum, there's enough empty space for nothing to happen.
any vids of these in an enclosure?
Nice subs!
like how those black cone jus look like two black eye
cheers mate! You had better lock your garage you don't want any hoodlums to come in there and nick your equipment yeah,?
Those speakers seem to be out of phase. Why?
Rolling Shutter
nice sundown
papu necesitamos la prueba de los subwoofers pero en su cabina
what the name of the amp??
Antonio Ibarra banda 7k
but why 33? :D
6:03 poor sundown sub :O
I want these
Where can i get these subs?
jay dinero you build them
DD esps?
Where the link gone ???😂😂
let the pole breath and use weight that wont interact with any magnetic fields
weighing parts is good too
Raaah 😂😂give me a woofer
agm's, while better at cycling than flooded cells are still best to just top off and not cycle. you are confusing nicd memory affects with with these batteries. There is no storage effect or memory on lead acid batteries, and you do not benefit in anyway from discharging an agm battery before charging.
brazilian systems?
unnecessary with new subs just play it low to moderate for a week and your are good.
he made these subs himself so unlike a machine made sub it is way more possible to have glue in places it shouldn't be so he is doing this to break any places loose that could be joined together
Ahhh ok
early.
I wish I could have them sundown subs omg!!!
John Lancaster those are ground zeros
I would pay 💰
How much to get one sub and awesome video
0:04 *
don't you think if the manufacture saw any benefit from "breaking in" as you say, because things could break if they are used as they are intended "per there specifications" then they would do this before they leave the factory. rubish
Thad ward if you speak to any reputable manufacturer of loudspeakers, in pro audio, Home theatre or car audio, they will advise you of a break in period. you would know this if you have measured the ts parameters of a brand new woofer, noticed that they are way off the manufacturers rated specs, then measured again after a break in period to fall within the specified parameters, like I have.
I'm very aware of this. I use a dats2 and a keithley 2015thd to measure my drivers before I build enclosures
and yes there is a significant change in the ts, but he said break not change in ts params. or you said
0:20 his voice xD
Can I have that sundown sub?
shadowDragoon12 no you cannot have it
I want your Premier kit.
U lost me when u used a Banda man no way your getting 9k lol
He benched the amp. He repairs these things, if anyone knows how much power they make, he does.
My stoner mind yoooooo
banda br ;)
I left a message on ur gain match video if u could check
there is NOOOOOOOOOOO way that's an 9kw amp :D
Yes there iiisssssssss way :)
it's Brazilian tech... research it
I have benched this amp and it does perform rated power :)
barevids how in the hell there is 9kw fitted inside of that? :D the size of that is like a quarter of a "normal" sized 9kw amp
You are referring to "normal" 9kw as Korean style class D amplifier board. This Banda is completely different technology, Digital class D, research the technology and you will see it requires much less components for the same power output as a traditional Korean class amplifier :)
Amps are getting smaller. Before class D came along, all amps were class AB. now, a 9k class AB amp would be about the size of the whole car!!!
you should see one of orions amp.. its rated 34k watts peak lol
barevids class D is class D, no such thing as a digital audio amp... unless all you want to hear is 1's and 0's... however 9kW is possible but I doubt it would be able to sustain it, so it will be a 10ms peak rating probably
First
Trevbossardee P nice!
I want one plzzzzzzz
give me one plzzzzzzz
put them in a box
would you like to sell me those subs ? : D
