Not exactly what i was asking about, but very close. Glad it sounds good. I'm pretty sure that adding a 15 cab will help out.
Do you find any volume issues, as in not having enough, when running both cabs?
I would say the opposite is certainly true. The combo's power amp won't deliver the full 500w output at 8 ohms, and total output with a bass amp is also about moving air around - the 2 x 10s just have too little surface area to move your pant legs properly. I really suspect that the 8ohm 410 is the way to go when coupled with this amp for 6 x 10s, but I got this older 15" for a proverbial song so I can't complain. I'd angle for a 410 if your wallet (and back) can handle it.
