Does anyone make a 4x12 or 4x10 cab

Make one yourself.....Just pick up some 3/4 in plywood make a box and get 4 good speakers and you can easilly make a Guitar cab that can be wired in stereo....It will probably cost you about $200-$300 for the Speakers and maybe $30 on Plywood and the speaker wireing is really easy....

Just a thought....
 
incidentally, it is a snap to rewire practically any cabinet. depending on the jack plate, you will need to (a) just rewire it, (b) drill a hole for the extra jack, or (c) replace the jackplate with a two jack model (you can wire for stereo yourself, even if the silkscreening says they are wired together (like from a cheap PA speaker). the only other consideration is the impedance of the speakers--- basically only an issue with tube amps.

p.s. avatar speakers are nice guys and easy to deal with. i have experience, but no affiliation with.

Actually there is an Issue with Impedance with solid state Amps, Some SS Amps can not handle Loads under 4 ohms so if you have Two 4 ohm speakers with would be better to wire them in Series to get 8 ohms rather than in paralell for 2 ohms...

Also if you Have Two 8 Ohm speakers it would be better to wire them in Paralell for 4 ohms as you get much more power output at 4 ohms than at 16 ohms.....

that can be run stereo, splitting the cab in half?

One other vendor to consider:

www.lopoline.com

I got to play through some of their cabs when I visited my buddy, Charles, at Power Station New England. Solid stuff and decent prices. They'll pretty much make what you want, so I imagine they could make a cab that could be run stereo, once you decide which drivers are going in and how you want them wired.

Cheers,

right. i assumed that the OP would do at least cursory research before soldering in a random jack. minimum impedance values should be clearly listed on the amp(s), and it seems pretty reasonable that he would take this into account.
increasing impedance with a ss amp will make the amp run cooler as well as reduce output, as youve mentioned. and truly, decreasing the minimum impedance by half with many ss amps will very likely be "ok", at the expense of higher temps and presumably shorter lifespan. i still have a big-knobbed cs-800 amp that spent 15 years driving 2 ohm loads--still works fine. then again the thing might cook off in minutes, perhaps particularly if its origins are chinese. 'net is full of amp death accounts and recounts.

increasing impedance with some tube amps can be a big problem, as can decreasing it (though perhaps to a lesser degree of danger, within reason).

Just take a regular 4x12" cabinet and wire it for stereo.

You'll need 4 16-ohm speakers.

Wire them in parallel pairs to a pair of 1/4" jacks and you'll have two 8-ohm pairs of speakers. Make sure that you connect two 1/4" jacks to each pair of speakers, then you can make or buy a short speaker cable like 12" long, and hook the two pairs together to run the box in mono, and you'll also be able to use it as a 4 ohm mono cabinet.

You beat me to it. Rep points coming your way.

yep. Those old CS-800's are built like tanks.
Back in the 80's, everyone bitched about them, but you know what? It was mainly because people were underpowering their PA systems. They thought it was Peavey's fault, but the reality is - they needed about 4 times the power they were running.

400 watts @ 4 ohms is just not enough power to efficiently drive a pair of 350 Watt 8 ohm speakers (You 'd really want about 1,000 watts at 4 0hms minimum if you are driving a 700 watt 4 ohm load just for a little headroom.)

I bet you could Weld two pieces of metal together with the power a CS800 puts out when it's bridged. :p
