Excellent and informative video. For years I've done the PA side of things and back line has always confused me. With a PA you follow the same guidance for matching the ohms but you use an amplifier that's at least 25% bigger than the speaker cab and always turn the power amp to full. This allows the cab and amp to deal with peaks in signal without clipping. The complete opposite of guitar amps. I've recently found out that guitar amps are designed to be driven hard and the cones are constructed to take it. This video filled in the last gaps. I knew that guitar gear would blow in certain circumstances, now I know when. Thank you.

@@alexmurphy5289 I was going to buy a combo but I decided that it's much cheaper to upgrade with a separate cabinet. The guy at the music store was visibly pissed that I wanted to return it
It's all about limiting the electrical current from the amp. High impedance means low current, ok for the amp but won't be very loud. Lower impedance means higher current. That's why your amp can blow, the low impedance speaker isn't controlling the current to a safe level, but allowing too much- and high current means maybe enough power to kill your amp. It's more likely to blow a fuse which every amp should have. Or keep the current controlled with the correct impedance speaker or higher.
Hey Dave. If you can read my comment I just left above maybe you can help me. You seem to know exactly what you’re talking about and yeah my hundred whitehead and JCM 900 4X12, isn’t very loud so I’ve already switched back to my 212 solid state. I need help
One thing to be aware of when combining amps into a single cabinet... A year ago I burned one output on a power amp by using that exact Vox amp in the other channel of a stereo cab. I thought it was really strange and started measuring with a multimeter. Apperently the Harley Benton cab I'm using has connected sleeves even in stereo (I guess they saved a few euros on a smaller switch with less poles). This combined with the Vox which apperently sends phase shifted voltage through both tip and sleeve made it so that my stereo power amp, which I've been using for years with this cab with no problems since the sleeve is 0 volts in both ends, got voltage from the Vox through the connected sleeves into its 0 and burned the amp. So from now on I'm always gonna pull out the multimeter to check whatever cab I'm connecting two amps to. If it beeps when you measure the two cables' sleeves, don't do it.
I've been thinking of running my AC30 with a Marshall cab (maybe a 2x12 or maybe a 4x12} but I'm curious if I can do that without blowing it up. Is that possible? I've seen Dean Deleo from STP do it and it's AMAZING sounding but I also don't want to destroy my AC30. LOL!
Thanks for a very clear explanation. However what about the effect on the volume - if any - when you connect an extra speaker to e.g. a combo with an internal speaker. Will the sound be bigger, louder? How would you describe the effect? Basically, what's the effect of connecting an extra speaker to the sound?
Can you please repeat how to turn a tube amp into a nuclear weapon? Instrument cable on speaker output it was? Can I destroy the earth when I additionally plug a speaker cable into the instrument jack? And what happens if I plug a second cab into the FX send? Would some kind of paradox appear and end the universe? Thanks.
I spy a Pompeii sticker on the strat matching their colors. 😉 Also, good video. I feel more informed about selecting and connecting amps and cabs than I had anticipated when I first clicked on. Always used combo amps before so this is exactly what I needed to know. Thank you.
If you have a bass amp head that is 1000 watts continuous at 4 ohm and the cab is 1600 watts peak at 8 ohm, will the cabinet blow up if the amp reaches its full volume?

You forgot running 2 mis-matched cabinets like an 8ohm and 16ohm cab. I think the impedance is 5.3 and you connect the 8ohm out to the 16ohm cab and the 4ohm out to the 8ohm cab. They have those series/parallel impedance boxes now where it eliminates the mismatch problems.

I have a Tone Master Twin Reverb. I like the sound of having a second cabinet.

Can you mix guitar speakers with different wattages, as long as the Ohms of the speakers match? For example, can I mix two Celestion 25-watt speakers with two Celestion 50-watt speakers for a 4x12 cabinet, as long as all four of the speakers are the same Ohms rating (e.g., all four speakers are 16-Ohms).
What’s the best speaker cable ? I have a Victory V40. On the back there are two possibilities 16ohm out, or 2 8ohm holes out. Can I connect just one of the two 8ohms to a 8ohms cab ? If so, which one ? Does it matter ? Those things could really be easier seriously
I think you missed an opportunity to talk about some cabs allowing you to plug 1 16ohm into another 16ohm and then into a cab to utilize a single 8ohm output on the amp
5:20 'Never exceed the minimum load.' So if minimum load is 8 ohm, DO NOT plug into 16 ohm slot. Exceed means more than. 16 exceeds 8. So no more than 8ohms. But 'minimum' means at least. So 'never exceed the minimum' means use exactly 8 ohms. No more, no less. Either I am correct, or someone needs to change the wording.
It's okay to run an 8-ohm amp into a 16ohm cab, you just won't get the amp's full power, and it may sound worse, you can't run a 16-ohm amp into an 8-ohm cab, you will nuke your amp. as long as the impedance of your amp is same or lower than the cab, it should not damage anything. Try to keep the same though for the best tone
Yeah, 100%. Everybody is patting this video on the back for clearing everything up, but I'm more confused than ever. If my amp head has a load of 4 ohms and my cabinet is 8 ohms, this video told me that is both good and bad.
Hello , thank you for this informative video, according to this, i can plug my ba210 vs ampeg combo to a 280W Peavey 8omh cabinet right with no problem?
I still have one question: I have a 100w solid state transistor amp. On the back it says: "Minimal Impedance 4 Ohms". That would mean that I could also use a 16Ohm speaker cabinet with it, but it will reduce the power output. Would it then be okay when the speaker cabinet has 60-70 Watts, because the higher impedance reduces the power output of the amp?
I'm also wondering about this. My amp is a peavey stereo chorus 212 combo, solid state 130w per side, 260w total. 4ohm minimum load per speaker, it has no switch like the vox one in the video cus its old af. I was thinking about rehousing the head part for easier transport with the option of using house speaker cabs at gigs. Any help appreciated.
@@cyborgcolin update. I tried it out and it worked perfectly. I do not even have difficulties that it the amp is no less loud. But the upgraded speaker is just great! (V30)
I have a Marshall tsl 602 and it has stock 80 watt Marshall wolverines in it. They sound muddy and my amp lacks sparkle, mids. What would be great speakers to bring this amp to life? Any help would be greatly appreciated. Thanks cool video too.
It's confusing to hear a phrase like "don't exceed the minimum load". Can you please explain? To me it sounds like "don't drive faster than the minimum speed limit." which obviously makes no sense.
I have 2 outputs on the back of my Marshall valvestate, it just says total load must not be less than 4 ohms, there isn't any selector switch, I'm just gonna plug into one and hope for the best!
Hello! I'm going to build a small guitar amp (a kit) that delivers up to 7W. My question is what kind of speaker should I use to get all the "juice" from this kind of amp? Thanks!
I emailed Marshall with this situation/question: "I have a Marshall Origin 212 cabinet that I want to pair my DSL1H with. The potential problem is the Origin 212 cabinet has two 16 ohm speakers wired in parallel making it 8 Ohms. I wired it in series making it a 32-Ohm unit. Will this be an issue for the 16-Ohm DSL1 head? Can I use a 32-Ohm cabinet with the 16-Ohm DSL1H?" Marshall's response: "The DSL-1 is a valve amplifier and therefor the Impedance must be correctly matched to avoid damage to the output transformer. I guess the only way you could use the Origin cab safely would be to disconnect one of the speakers. If you need it to be an 8 Ohm cab for other amps, maybe switch one of the speakers so 8 & 16 can be selected? Not what I wanted to hear lol.
Im buying blackstar ID60 and I'm gonna plug it in the bugera 212ts. The cabinet has the power of 160 watts. Can I get the 160 watts out of it using only 4 ohms?
I've heard if your looking for reliability it isn't good to use speakers capable of to high of watts in comparison to the amp. If the amp struggles to fully move the speaker it doesn't move air that would otherwise combat build-up of heat in the voice coil.
Oh wow so I have literally been doing this all wrong for years... I have the mentioned 1936 2x12 cab and always ran that into the 16Ohm output on my DSL2000 😬 Thanks to your video i now know to connect that to the 8 Ohms output on the amp. But what if I want to run another 2x12 cab along with the 1936 2x12 on the same head? Do I then just run another cable from the 8 Ohms output to an 8 Ohms input on the 2nd cab?
Great video, I love all your content. I have a question regarding wattage, some amps allow you to change the wattage, example: from 20w/5w/1w, if I keep it on 1watt is it safe to assume that I can use a 2 watt speaker if it existed? Thank you
Why would you want a 2 watt speaker, and where would you find one? I suppose in theory yes, but I doubt you'll ever have to worry about it. Most guitar speakers will have a rating that will comfortably handle your 20 watt amp at any setting.
@@castleanthrax1833 thanks for the reply. in theory. I guess this is what I meant My amp is too loud, tube amp, built in attenuator allows me to turn it down to 1 watt but it is still too loud, I have a 12” 60 watt speaker, I wish there was a little speaker out there, and “if there were” and the speaker was anything below 20 watts which is my amps standard power can I play it as long as I attenuate my amp down
QUESTION. I have two PPC212OB 2x12 orange cabs. And a orange crush pro 100 Can I run my amp through both those cabs? If so do I use both plugs on the back on the amp or daisy chain them.
What kind of response would a speaker be if it was a higher wattage than the amplifier output? I understand that the 7 watt out into a 100 watt cabinet is not a big deal, but will it really amplify the signal well or would it be better to use a lower wattage speaker for more dynamic response?
The speakers act as a resistive load, so it is more about the impedance when it comes to driving them. The wattage is a measurement of what it can safely handle. High wattage cab is louder at lower matched impedances. At higher matched impedance it is quieter. At mismatched impedance which is only safe to do with double the impedance on the speaker load i.e. 4ohm amp to 8 ohm load , 8 ohm amp to 16 ohm load quieter with more midrange. I drive 100 watt speaker loads with a 60 watt amp all the time at 8 ohms and it is super loud and responsive. Tube watts are always loud compared to solid state.
QUESTION ......... So I have a Peavey Windsor head and a 2x12 cab. The cab is like the Marshall 1936 cab as to where it has the two inputs and a switch to change from 8 Ohm or 16 Ohm. The Windsor head has a switch to change Ohm from 4 - 8 -16. Can I run speaker cables out of both amp outputs into cab? (Trying to get stereo) If so, should the cab and amp be set to 16 Ohm?
I have a 15watt amp, im planning to swap the speaker with the same 8ohm impedance and with the following specs: Maximum Power: 300 watts - Impedance: 8 Ohms - Sensitivity: 100dB / W / M +- 1dB - Frequency Range: 70Hz-12KHz Will it sound ok? Wiĺ it work? Thanks in advance!
Let me get this straight: If I want to use a stereo capable cabinet with 4 Ohms Mono and 8 + 8 Ohms Stereo, my amp should have two 8 Ohms input jacks whilst making sure the amp has a minimum load of 4 Ohms?
5:30 "But always remember the golden rule, never exceed the minimum load stated on the back of an amp." Exceed the minimum? Did he mean go below the minimum? So 8 ohm amp + 16 ohm cab = OK 8 ohm amp + 8 ohm cab = OK 8 ohm amp + 4 ohm cab = Destruction
I'm so confused. I always thought what you said: that your speakers need to be able to handle more wattage than the amp puts out. But in searching around the internet I've found a dozen or more reputable places that say the opposite, that "It is always recommended to use approximately twice as much amplifier power as the speaker’s power rating." What am I missing?
I think I've parsed it out, but yeah, I feel like this was more phrased poorly: "It's vitally important that you match these impedances, and don't drop below that minimum load." I think he's discussing the CABINET here. The minimum stated load of a cabinet SHOULD NOT BE LOWER than the amplifier. "Always follow the golden rule: Never exceed the minimum load stated on the back of an amp." Now he's discussing the AMPLIFIER. The minimum load of an amplifier SHOULD NOT BE HIGHER than the cabinet. So I THINK -- and from a nine-minute explanation, you'd REALLY THINK THIS WOULD BE CLEARER -- that he means the OHM number on the back of the amp should be lower or the same, but not higher, than the OHM number on the back of the cabinet.
What about when you're connecting multiple cabs together (from only one output on the head)? If I am running a cable from a tube head into and 8 ohm cab, and then a cable from that cab into another 8 ohm cab, which output should I connect it to on the head (4, 8, or 16?)
Hi! Nice video Sir. Thank you! I do have an Ashdown Five Fifteen Bass Amp Combo at 100 watts of power.. It has an extension speaker feature and it says at 8 ohms..So If im going to add an extension cabinet to it, i do need a cabinet at 8 ohms and max power handling not less than the 100w.. Do i get it right?
Hi! I’m new to this, so I appreciate any help regarding one question: I have a stereo guitar amp head (25w/Chanel) + stereo cab (both ENGL). Can I connect 2 cables to the head and then to the 2 inputs of the cab in Stereo!
Hopefully you all are still answering questions. I have 40 watt tube Marshall combo. 16 ohms single, 8 ohms for a 2x12. I have 2 beautiful 8 ohm 25 watt Greenbacks. Am I good to go? Obviously i use the 8 ohm out. The cabinet is not wired yet so ill have to figure that out as well. Thanks!
@@PeterDad60 Thanks. I admit this is confusing. A guy on the Marshall forum says yeah, i'm good to go, Wire them in series. Honestly at this point I may just rig up a quick 16 OHM single cab with the original crappy speaker for now (upgrade later). Smaller to load/unload anyways.
One thing I didn't understand. I have one 4x12 speakers 16ohm each one. I must consider so this is a 4 ohm result? Thus, considering the 16 ohm jack on the orange amp, it just may be used in a 1x12 16ohm speaker, is that?
Thanks for the help. I just bought the Peavey Invective MH which is switchable between 16 ohms and 8 ohms, the cab I bought is the EVH 5150 2x 12 60 watt, it says 16 ohms. Which switch should I have the Peavey head on 8 or 16??
I plugged my dsl20 head's 1x16 ohm connection to a single 8 ohm speaker, a line six spider 75 watt combo to be specific. I didn't crank it and only played about 20 minutes. Didn't sound very good. But I'm wondering if I could have damaged my amp? Damn the speaker.
got a question, if im playing live with an amp head that has a low power 50 watt mode and a high power 100 watt mode and the venue’s speaker is only 75 watt would i still blow it if i put it in 50 watt mode
One thing is not exactly clear about the wattage: wouldn't I have to AT LEAST match the wattage of the amp to the one of the cabinet? I thought that using a lower wattage amp on a higher wattage cabinet would stress the amp and, in extreme cases, blow it up. Please correct me if i'm wrong.
The wattage on the cabinet is the amount it can safely handle, and has no bearing on the volume it produces. Why else would Marshall (or any other amp manufacturers) load a 412 with 4 X 75 watt speakers? Marshall have made that cabinet to pair with a 100 watt amp, so you can be comfortable that it's OK.
Hi dude, awesome content. Listen you can help me? I have a Blackstar head and two cabinets, one cabinet is 8homs and other is 16homs. My head have 16homs output and other for 1x8 and next say 2x16. I can plug 8homs cabinet in 1x8 and my 16homs cabinet in 2x16? Thanks

It's okay to run an 8-ohm amp into a 16ohm cab, you just won't get the amp's full power, and it may sound worse, you can't run a 16-ohm amp into an 8-ohm cab, you will nuke your amp. as long as the impedance of your amp is same or lower than the cab, it should not damage anything. Try to keep the same though for the best tone
dont run a cab with a lower impedance than amp it will proably die
he means exceed minimum load going below or going on the negative side of the y axis.
Yeah, 100%. Everybody is patting this video on the back for clearing everything up, but I'm more confused than ever. If my amp head has a load of 4 ohms and my cabinet is 8 ohms, this video told me that is both good and bad.
Hello , thank you for this informative video, according to this, i can plug my ba210 vs ampeg combo to a 280W Peavey 8omh cabinet right with no problem?
I still have one question: I have a 100w solid state transistor amp. On the back it says: "Minimal Impedance 4 Ohms". That would mean that I could also use a 16Ohm speaker cabinet with it, but it will reduce the power output. Would it then be okay when the speaker cabinet has 60-70 Watts, because the higher impedance reduces the power output of the amp?
I'm also wondering about this. My amp is a peavey stereo chorus 212 combo, solid state 130w per side, 260w total. 4ohm minimum load per speaker, it has no switch like the vox one in the video cus its old af. I was thinking about rehousing the head part for easier transport with the option of using house speaker cabs at gigs. Any help appreciated.
@@cyborgcolin update. I tried it out and it worked perfectly. I do not even have difficulties that it the amp is no less loud. But the upgraded speaker is just great! (V30)
@@benesombrilla thanks a bunch for the reply! Full steam ahead!
Great Video! So I have an orange th30 just like the one shown in the video. Can I hook up one 16ohm cab and one 8ohm cab??
Excellent video. Thanks!
I have a Marshall tsl 602 and it has stock 80 watt Marshall wolverines in it. They sound muddy and my amp lacks sparkle, mids. What would be great speakers to bring this amp to life? Any help would be greatly appreciated. Thanks cool video too.
Buy a combo or your amp might catch fire and blow up...got it!
lololololol
Just don't buy a Marshall 🙄
*EVH 5150 combo intensifies*
Thanks man!! That high Hertz with the nuclear bomb, drove my Jack Russel nuts!
It's confusing to hear a phrase like "don't exceed the minimum load". Can you please explain? To me it sounds like "don't drive faster than the minimum speed limit." which obviously makes no sense.
He explained it. Clearly means 100 watt head needs the speakers to take at least 100 watts..
Thanks , this was really helpful!
I have 2 outputs on the back of my Marshall valvestate, it just says total load must not be less than 4 ohms, there isn't any selector switch, I'm just gonna plug into one and hope for the best!
4, 8 or 16 ohms total is fine!
Hello! I'm going to build a small guitar amp (a kit) that delivers up to 7W. My question is what kind of speaker should I use to get all the "juice" from this kind of amp? Thanks!
I emailed Marshall with this situation/question: "I have a Marshall Origin 212 cabinet that I want to pair my DSL1H with. The potential problem is the Origin 212 cabinet has two 16 ohm speakers wired in parallel making it 8 Ohms. I wired it in series making it a 32-Ohm unit. Will this be an issue for the 16-Ohm DSL1 head? Can I use a 32-Ohm cabinet with the 16-Ohm DSL1H?"
Marshall's response:
"The DSL-1 is a valve amplifier and therefor the Impedance must be correctly matched to avoid damage to the output transformer.
I guess the only way you could use the Origin cab safely would be to disconnect one of the speakers.
If you need it to be an 8 Ohm cab for other amps, maybe switch one of the speakers so 8 & 16 can be selected?
Not what I wanted to hear lol.
Im buying blackstar ID60 and I'm gonna plug it in the bugera 212ts. The cabinet has the power of 160 watts. Can I get the 160 watts out of it using only 4 ohms?
How about plugging a 32 ohm cabinet (two 16 ohm speakers wired in series) to a 16 ohm tube amp?
I've heard if your looking for reliability it isn't good to use speakers capable of to high of watts in comparison to the amp. If the amp struggles to fully move the speaker it doesn't move air that would otherwise combat build-up of heat in the voice coil.
Interesting
Hmmm
Providing your ohms are matched correctly there's no problem. A 1 watt head will happily work with a 300 watt cabinet.
Oh wow so I have literally been doing this all wrong for years... I have the mentioned 1936 2x12 cab and always ran that into the 16Ohm output on my DSL2000 😬 Thanks to your video i now know to connect that to the 8 Ohms output on the amp. But what if I want to run another 2x12 cab along with the 1936 2x12 on the same head? Do I then just run another cable from the 8 Ohms output to an 8 Ohms input on the 2nd cab?
Great video, I love all your content.
I have a question regarding wattage, some amps allow you to change the wattage, example: from 20w/5w/1w, if I keep it on 1watt is it safe to assume that I can use a 2 watt speaker if it existed? Thank you
Why would you want a 2 watt speaker, and where would you find one? I suppose in theory yes, but I doubt you'll ever have to worry about it. Most guitar speakers will have a rating that will comfortably handle your 20 watt amp at any setting.
@@castleanthrax1833 thanks for the reply.
in theory.
I guess this is what I meant
My amp is too loud, tube amp, built in attenuator allows me to turn it down to 1 watt but it is still too loud, I have a 12” 60 watt speaker, I wish there was a little speaker out there, and “if there were” and the speaker was anything below 20 watts which is my amps standard power can I play it as long as I attenuate my amp down
QUESTION.
I have two PPC212OB 2x12 orange cabs.
And a orange crush pro 100
Can I run my amp through both those cabs?
If so do I use both plugs on the back on the amp or daisy chain them.
So if I Plug an 8 ohm 100W amp into a 16 ohm 240 Watt Cabinet will I damage anything??? (Solid State Amp)
Nah, you should be fine, but the cabinet will feel less powerful
What kind of response would a speaker be if it was a higher wattage than the amplifier output? I understand that the 7 watt out into a 100 watt cabinet is not a big deal, but will it really amplify the signal well or would it be better to use a lower wattage speaker for more dynamic response?
The speakers act as a resistive load, so it is more about the impedance when it comes to driving them. The wattage is a measurement of what it can safely handle. High wattage cab is louder at lower matched impedances. At higher matched impedance it is quieter. At mismatched impedance which is only safe to do with double the impedance on the speaker load i.e. 4ohm amp to 8 ohm load , 8 ohm amp to 16 ohm load quieter with more midrange. I drive 100 watt speaker loads with a 60 watt amp all the time at 8 ohms and it is super loud and responsive. Tube watts are always loud compared to solid state.
So you say i have a 6watt laney mini amp. Use the headphone out to the input jack of the 20W amp of a diferent brand? Will it work
QUESTION ......... So I have a Peavey Windsor head and a 2x12 cab. The cab is like the Marshall 1936 cab as to where it has the two inputs and a switch to change from 8 Ohm or 16 Ohm. The Windsor head has a switch to change Ohm from 4 - 8 -16. Can I run speaker cables out of both amp outputs into cab? (Trying to get stereo) If so, should the cab and amp be set to 16 Ohm?
I have a 15watt amp, im planning to swap the speaker with the same 8ohm impedance and with the following specs:
Maximum Power: 300 watts - Impedance: 8 Ohms - Sensitivity: 100dB / W / M +- 1dB - Frequency Range: 70Hz-12KHz
Will it sound ok? Wiĺ it work? Thanks in advance!
I have a 4x12 Marshall 1960 cab and a 2x12 Marshall 1936 cab. Using a 100 watt Marshall silver jubilee. How would I connect if I wanted to use both?
thoroughly enjoyed those explosions
Let me get this straight: If I want to use a stereo capable cabinet with 4 Ohms Mono and 8 + 8 Ohms Stereo, my amp should have two 8 Ohms input jacks whilst making sure the amp has a minimum load of 4 Ohms?
Quick question. What if I only have 8ohms out put for speaker cab and my speaker cab is 16 ohms can I still plug it in without worrying anything.
The amp i want has an option to set thr wattage to 50 or 100. If i set it to 50 watts, would i still need a 100+ watt cab?
Also make sure to look at both sides before crossing or, you guessed it, boom!
5:30 "But always remember the golden rule, never exceed the minimum load stated on the back of an amp."
Exceed the minimum? Did he mean go below the minimum?
So 8 ohm amp + 16 ohm cab = OK
8 ohm amp + 8 ohm cab = OK
8 ohm amp + 4 ohm cab = Destruction
Exceed the minimum, there's definitely something I don't like about that phrase.
SHould ALWAYS exceed minimum load rating ha
Is really how it goes?
@@paginini yeh its Minimum,so ya cant go Below it
Lesser ohms = More power, More explosions
I'm so confused. I always thought what you said: that your speakers need to be able to handle more wattage than the amp puts out. But in searching around the internet I've found a dozen or more reputable places that say the opposite, that "It is always recommended to use approximately twice as much amplifier power as the speaker’s power rating." What am I missing?
I think I've parsed it out, but yeah, I feel like this was more phrased poorly:
"It's vitally important that you match these impedances, and don't drop below that minimum load."
I think he's discussing the CABINET here. The minimum stated load of a cabinet SHOULD NOT BE LOWER than the amplifier.
"Always follow the golden rule: Never exceed the minimum load stated on the back of an amp."
Now he's discussing the AMPLIFIER. The minimum load of an amplifier SHOULD NOT BE HIGHER than the cabinet.
So I THINK -- and from a nine-minute explanation, you'd REALLY THINK THIS WOULD BE CLEARER -- that he means the OHM number on the back of the amp should be lower or the same, but not higher, than the OHM number on the back of the cabinet.
So it is save to connect a 100 Watt Tubeamp with two 90 Watt Cabinets, right?
Thanks for the info man!
What about when you're connecting multiple cabs together (from only one output on the head)? If I am running a cable from a tube head into and 8 ohm cab, and then a cable from that cab into another 8 ohm cab, which output should I connect it to on the head (4, 8, or 16?)
Hi! Nice video Sir. Thank you!
I do have an Ashdown Five Fifteen Bass Amp Combo at 100 watts of power.. It has an extension speaker feature and it says at 8 ohms..So If im going to add an extension cabinet to it, i do need a cabinet at 8 ohms and max power handling not less than the 100w.. Do i get it right?
Hi! I’m new to this, so I appreciate any help regarding one question: I have a stereo guitar amp head (25w/Chanel) + stereo cab (both ENGL). Can I connect 2 cables to the head and then to the 2 inputs of the cab in Stereo!
Hopefully you all are still answering questions. I have 40 watt tube Marshall combo. 16 ohms single, 8 ohms for a 2x12. I have 2 beautiful 8 ohm 25 watt Greenbacks. Am I good to go? Obviously i use the 8 ohm out. The cabinet is not wired yet so ill have to figure that out as well. Thanks!
If your amp is a DSL40C No! If your amp is the DSL40CR the answer is YES. Two 8 ohm cabs = 4 ohm total load!
@@PeterDad60 Thanks. I admit this is confusing. A guy on the Marshall forum says yeah, i'm good to go, Wire them in series. Honestly at this point I may just rig up a quick 16 OHM single cab with the original crappy speaker for now (upgrade later). Smaller to load/unload anyways.
Brilliant video, i wish i understood any of it
One thing I didn't understand. I have one 4x12 speakers 16ohm each one. I must consider so this is a 4 ohm result? Thus, considering the 16 ohm jack on the orange amp, it just may be used in a 1x12 16ohm speaker, is that?
Thanks for the help. I just bought the Peavey Invective MH which is switchable between 16 ohms and 8 ohms, the cab I bought is the EVH 5150 2x 12 60 watt, it says 16 ohms. Which switch should I have the Peavey head on 8 or 16??
I plugged my dsl20 head's 1x16 ohm connection to a single 8 ohm speaker, a line six spider 75 watt combo to be specific. I didn't crank it and only played about 20 minutes. Didn't sound very good. But I'm wondering if I could have damaged my amp? Damn the speaker.
got a question, if im playing live with an amp head that has a low power 50 watt mode and a high power 100 watt mode and the venue’s speaker is only 75 watt would i still blow it if i put it in 50 watt mode
Could i safely use a powerstage 700 on a 40w 1x10 or 1x12 for practice? I would keep it low volume
im very curious with this idea, modeling amp with a speaker cabinet, is it a good idea? will it work? or will it just go boom?
I’ve been running a very vintage Marshall 1959 head with 4 16 ohm speaker cabs for decades sans issue.
4 ohm amp to 16 ohm speaker?
@@jaceydurland9098 The amp has a selector for 4, 8 and 16. I use 4, 16 ohm cabs which creates a 4 ohm load.
My amp is more important than me? 🥺
The amp is resaleble. Your Organs can only be bought once.
If you own a vintage Dumble amp than possibly it is
Still i think enough money maby 8 grand u can buy a vintage dumbell but an organ i dnt know baby 60 gran ha ha
A question for you.
I’ve got a JVM205H can it handle a stack 1960a and 1960b cabinets.
How would you go about it
One thing is not exactly clear about the wattage: wouldn't I have to AT LEAST match the wattage of the amp to the one of the cabinet? I thought that using a lower wattage amp on a higher wattage cabinet would stress the amp and, in extreme cases, blow it up. Please correct me if i'm wrong.
The wattage on the cabinet is the amount it can safely handle, and has no bearing on the volume it produces. Why else would Marshall (or any other amp manufacturers) load a 412 with 4 X 75 watt speakers? Marshall have made that cabinet to pair with a 100 watt amp, so you can be comfortable that it's OK.
Hi dude, awesome content. Listen you can help me? I have a Blackstar head and two cabinets, one cabinet is 8homs and other is 16homs. My head have 16homs output and other for 1x8 and next say 2x16. I can plug 8homs cabinet in 1x8 and my 16homs cabinet in 2x16? Thanks
