Need help identifying Sunn speaker cabs / Help combining cabs.
 

Hey there,
I play in 2 bands, one is a lighter uptempo post-punk kind of style and the other one is a low drop B down-tuned doom-sludge-crust-punk-hardcore type (yup). I was thinking of expanding my bass rig to something more heavy on the low side, since we're only a 3 piece band.

I've got an SVT-CL combined with a 810EN. I was thinking about adding a 2x15 cab righ beside. I came across 2 unidentified Sunn cabs. The seller says they're 2x 15" cab, asking about 50$ a piece. Don't know the condition or model. I'm waiting on a couple of answer from the seller.

That's where someone here might pitch-in to help a little. The one up top looks bigger than the one on the bottom. The bottom one is definitely a 15". However, I'm questioning if the top one isn't a 4x12 instead.
Someone can help here?


Other thing, could I fit them into my rig?
My SVT-CL has one speakon and two 1/4" speaker outputs, I'd need 3, no? Right now I'm using the speakon connector for my 810EN, but I'm assuming that the 2 other speaker outputs are disabled while the speakon is used. Is it the case?

How can I plug them all? Sorry for the noob question, I've always had to deal with only one cab up until today. Any help would gladly be appreciated.

There are several factors you need to consider. 1st, the total impedance of all the cabs. The SVT will do well with 2 or 4 ohms, and not much else. So, knowing the total is key. 2nd, in most cases, matched cabs will perform better than a mixed bag. If you're looking for super sub-sonic bass tones, you've got the wrong set up, and no amount of larger spkr size cabs will make up for that. I would suggest you read the faq's and stickies at the top of the amps page for a boatload of good info. Best of luck to you.
