Members David E H Posted April 25, 2009 Members Share Posted April 25, 2009 I'm considering what I could build with what random speakers I have. I have two pairs of 12".(one pair is 8 ohms per speaker, the other pair is 16 ohms) I also have a pair of 10" at 8 ohms a piece. They're all about the same quality....the 12"s and 10"s come from old Wharfedales, and the other 12" come from a Hammond M101. What type of cab should I put together for these? How would I go about making a 4x12 with speakers of different impedance? And if I make a cab with two 12" and two 10", would I mount the 10" on top of the 12"? Perhaps I should just make two cabinets.....I'm just trying to see what I can put together. Thanks. Link to comment Share on other sites More sharing options...
Members Curtis.Fagan Posted April 26, 2009 Members Share Posted April 26, 2009 You'd have to get the speakers with the same impedances to make it a cab you could run with one head. Otherwise you could get a stereo power amp, and run the speakers seperately... otherwise, it doesn't add up and it'll damage you amp. -Curtis Link to comment Share on other sites More sharing options...
Members Damull1 Posted April 26, 2009 Members Share Posted April 26, 2009 I've seen cabs that had two 12's and two 10's. They put the 12's and 10's in opposite corners (12's in the top left and bottom right and 10's in the top right and bottom left). But Curt's right, they'll have to be of the same impedance.

Members David E H Posted April 26, 2009 Author Members Share Posted April 26, 2009 Okay, well it should work then because my speakers are: -two 10", 8 ohms-two 12", 8ohms-two 12", 16 ohms Link to comment Share on other sites More sharing options...
Members WRGKMC Posted April 26, 2009 Members Share Posted April 26, 2009 Doesnt Gibson amps have the 2+2 design? I know fender has some with different combinations as well. You may want to partition the 12s from the 10s in the same cabinet. You dont have to stagger them in corners inless you want to. A cool design might be a slant cab type desigh with the 10s pointing up a bit. Link to comment Share on other sites More sharing options...
Members Belva Posted April 26, 2009 Members Share Posted April 26, 2009 Put all four of the 8 ohm speakers in one cab with series/parallel wiring & you have an 8ohm cab. Put the two 16's in a seperate cab paralleled & you have another 8ohm cab. Then your 8ohm head is happy with either cab. And if you have a 4 ohm option on the amp it will most likely have the speaker outs paralleled so, once again your amp head is happy running both. I like your "run watcha brung" philosophy.

I like that idea, and every amp I have besides my Super Reverb(which has great speakers already) is an 8 ohm amp. Link to comment Share on other sites More sharing options...
Members Curtis.Fagan Posted April 27, 2009 Members Share Posted April 27, 2009 I still dig the idea. This is cool. I worry though that there might be some phase issues inherent to the offset speaker designs. -Curtis Link to comment Share on other sites More sharing options...
Members Damull1 Posted April 27, 2009 Members Share Posted April 27, 2009 You shouldn't have phasing issues. If anything you might have a wider spread of highs and lows with the different sized speakers. Link to comment Share on other sites More sharing options...
Members NyteOwl Posted April 27, 2009 Members Share Posted April 27, 2009 Doesnt Gibson amps have the 2+2 design?Yeah, they have a 2x12/2x10 Goldtone series cab... Link to comment Share on other sites More sharing options...

If anything you might have a wider spread of highs and lows with the different sized speakers. Yeah, that's sorta what I'd like to see happen with it. I realized, another crazy option I could do would be running the two 16 ohms in parallel, with three other 8 ohm speakers to have a cab with 5 speakers....haha Link to comment Share on other sites More sharing options...
Moderators isaac42 Posted April 28, 2009 Moderators Share Posted April 28, 2009 You shouldn't have phasing issues. If anything you might have a wider spread of highs and lows with the different sized speakers. Might. Not necessarily. If one set already has a wide, flat response, the second set would almost unavoidably make that worse. However, the resulting sound might be preferable. It all depends on one's taste.

Members Belva Posted April 28, 2009 Members Share Posted April 28, 2009 I'm running a cab that has 2 12" CTS & 2 8" Grundig speakers. All 8 ohm. Sound has a full spectrum. And this was a "use what I have" cab. Had a piece of some good 3/4" birch ply and some time to kill. I ran the speakers in roughly the same configuration as described so I could fit them in. Never know until you try. Link to comment Share on other sites More sharing options...
