Members theDogger Posted February 17, 2009 Members Share Posted February 17, 2009 Looking to take advantage of all the possibility of speakers combos. This is for a 4x12 cab that I am almost finished with. So is that right? If not can it be done? If so How? I am waiting on the speakers to come in....otherwise I would have wired them up and tested with a ohm meter thanks theDogger Link to comment Share on other sites More sharing options...
Members nakedzen Posted February 17, 2009 Members Share Posted February 17, 2009 Wire each pair in parallel and then wire the pairs in series. This makes 16 ohms total. I'd put them in the cab in an x-pattern, like this: XOOX This would give you a more balanced sound. Link to comment Share on other sites More sharing options...
Members theDogger Posted February 17, 2009 Author Members Share Posted February 17, 2009 Ok maybe we are not on the same page. I want 4 different jacks on the back of 1-4x12 cab. So my jack plate will have 4 different jacks.1-8 Ohm (2- Greenbacks)1-8 Ohm (2- G12T)1-8 Ohm (1- Greenbacks & 1- G12T)1-16 Ohm (4- All Speakers) This should give me the most flexibility when connecting to heads and I get to choose what combo I want. theDogger Link to comment Share on other sites More sharing options...
Members Sixtonoize Posted February 17, 2009 Members Share Posted February 17, 2009 You'll have to have a few switches in there as well... The drawing you did has enough connections to make all the speakers parallel no matter which jack you'd plug into. Link to comment Share on other sites More sharing options...
Members OverDriven Posted February 17, 2009 Members Share Posted February 17, 2009 Wow that made my head hurt. In short, no that will not work, but it will probably blow your amp up. You need to design a switching system. Link to comment Share on other sites More sharing options...
Members theDogger Posted February 17, 2009 Author Members Share Posted February 17, 2009 The drawing you did has enough connections to make all the speakers parallel no matter which jack you'd plug into.Ok if that is true then I could still get away with running 3 jacks 1-8 Ohm (2- Greenbacks) 1-8 Ohm (2- G12T) 1-16 Ohm (4- All Speakers) that should be ok right? If not can you please point me in the right direction to get that done... theDogger Link to comment Share on other sites More sharing options...

You may need to flip the polarity of one pair of speakers if I'm looking at this right. Link to comment Share on other sites More sharing options...
Members theDogger Posted February 17, 2009 Author Members Share Posted February 17, 2009 ok please bear with me ask I may not be terming this right. But as I look at it now. The 2 sets are wired in parallel give a 8 Ohm load. Then by wiring 2-8 Ohm loads in series I get a 16 ohm load for all 4-speakers correct. Where would it be out of phase? theDogger Link to comment Share on other sites More sharing options...
Members n0fx Posted February 17, 2009 Members Share Posted February 17, 2009 Yes...but only with jacks with switching contacts and the wiring can get complicated. Link to comment Share on other sites More sharing options...
Members theDogger Posted February 18, 2009 Author Members Share Posted February 18, 2009 Yes...but only with jacks with switching contacts and the wiring can get complicated. Ok so using 2-stereo jacks for the 8 Ohms and 1 stereo jack for the 16 Ohm Like this Right? theDogger Link to comment Share on other sites More sharing options...
Members theDogger Posted February 19, 2009 Author Members Share Posted February 19, 2009 anyone? Link to comment Share on other sites More sharing options...
Members theDogger Posted February 24, 2009 Author Members Share Posted February 24, 2009 ok did some more digging and this is what I have come up with and what I am using for the connection? Looking for input.. A = two speakers in parallel @ 8 ohm total load B = two speakers in parallel @ 8 ohm total load C = takes two 8-ohm parallel circuits and combines them in series @ 16 ohm total load (Input A & B) Switchcraft - Double Closed Circuit #14B (Input C) Switchcraft Stereo Jack #12B I am assuming that this is correct? Anyone? thanks theDogger Link to comment Share on other sites More sharing options...
Members Cap'n Ahole Posted February 25, 2009 Members Share Posted February 25, 2009 If you gave each speaker or PAIR its own jack & did the conecting with external jumpers you made up, you could get any combo you wanted. I did that with a 2x12.. I can run it stereo, series or parallel. This is correct: A = two speakers in parallel @ 8 ohm total loadB = two speakers in parallel @ 8 ohm total loadC = takes two 8-ohm parallel circuits and combines them in series @ 16 ohm total load Link to comment Share on other sites More sharing options...
