sebowden Posted December 26, 2016 Share Posted December 26, 2016 I have a Peavey 410TX cab that I would like to wire into parallel for use with an SVT-VR at 2Ohms. Will it work? Teach me your ways. Quote Link to comment Share on other sites More sharing options...
Phil Starr Posted December 26, 2016 Share Posted December 26, 2016 Probably but your biggest problem is the tweeter/crossover which I know nothing about. I think you have four 8ohm speakers in there and they will be wired in series/parallel that is two pairs of speakers wired in series and then the pairs wired in parallel. Simply wiring the four speakers in parallel will give you 2ohms. The only problem will be the crossover, if it is a simple high pass filter it will still protect the horn, if it is a 'proper' crossover it will operate at the wrong frequency for the 2ohm bass units.That will change the sound of the cab. If you don't need the horn then you could just disconnect it and the crossover. Quote Link to comment Share on other sites More sharing options...

[/quote] Sorry, forgot to mention - tweeter and crossover are disconnected. They sounded awful! Will the cab lose any power at 2Ohms? Is there a foolproof guide for how to do this?

markstuk Posted December 26, 2016 Share Posted December 26, 2016 Why are you wanting to rewire for 2 Ohms if you think it will lose power? I presume you're doing this so that your amp will make more power into the new configuration? Quote Link to comment Share on other sites More sharing options...
pete.young Posted December 26, 2016 Share Posted December 26, 2016 I would guess he is doing it because Ampeg don't recommend you use anything other than 4 or 2 ohm load and he doesn't want to buy another cab. Quote Link to comment Share on other sites More sharing options...

[/quote] Correct. I'm saving for the 212AV though. Just need something for now. Will it lose power?

pete.young Posted December 26, 2016 Share Posted December 26, 2016 Your question is essentially meaningless. The cab doesn't have any power to gain or lose. Power comes from the amplifier. The 410TX is rated by Peavey as 350W RMS and this won't change whether it is wired at 8 ohms or 2 ohms. These are very substantial and tough cabs (I had one for a while), but it's not possible to say whether an SVT-VR will damage it or not. If you decide to go ahead, once you've rewired it, start at low volume, listen carefully and turn it down if it sounds distorted. There's a wiring schematic here, second diagram down http://www.colomar.com/Shavano/4x12wiring.html. They're also pretty cheap second hand - the safest route is to buy another one and use them both to give you a 4 ohm load. That'll probably sound a lot better than a 2x12 too, though slightly less portable. Quote Link to comment Share on other sites More sharing options...
sebowden Posted December 27, 2016 Author Share Posted December 27, 2016 (edited) Thanks for the help man! This diagram correct?

Not a huge fan of the peavey's sound, but it has served me very well. Edited December 27, 2016 by sebowden Quote Link to comment Share on other sites More sharing options...
pete.young Posted December 27, 2016 Share Posted December 27, 2016 (edited) Diagram looks about right. Make a note of the original wiring - you'll need to put it back if you want to sell it, there's not much of a market for 2Ohm cabs. Think I'd want to hear that cabinet before deciding whether it was perfect or not. There are plenty of other good 2x12s, some of which occasionally come up for sale in the forums here.

sebowden Posted December 27, 2016 Author Share Posted December 27, 2016 Just plugged the SVT in for the first time. WOW. Cab works a charm, too. No distorting, but only got the volume to 9 O'clock so will see how it sounds at rehearsal tomorrow. Thanks for your help. Best birthday ever! I would obviously try the cab first! I'm usually a 15 inch cab guy - the 2x12 is like a middle ground to my ears, but only heard youtube demos. Quote Link to comment Share on other sites More sharing options...
Phil Starr Posted December 28, 2016 Share Posted December 28, 2016 Glad to see a happy ending. The power handling will not be affected as all the speakers are still sharing the power equally. As you are now working through a two ohm cab it will be worth using a high grade Jack lead to connect the cab to the amp. Operating into two ohms means you need higher current handling. Jack plugs will struggle with two ohms and if you can adapt the cab to use speakons then that would be worth doing for long term reliability.

sebowden Posted December 29, 2016 Author Share Posted December 29, 2016 I've been using a rock-wire cable, but its only 2.5mm.... I'll upgrade at some point Quote Link to comment Share on other sites More sharing options...
