Replace sunfire true sub with what ?

avrij..in a smaller room the rel strata II or III works quite well; very musical, slam when required, and a ten inch downfiring woofer..small footprint..

about 600 to 900 used; III model is more expensive and worth it if you can swing it....better crossover controls, low FR volume in addition to overall volume control, remote for bass output (very useful)

i had a rel strata III and currently have a sunfire signature..

the rel was better for music(seamless) and the sunfire was better for home theatre(incredible slam and small footprint)...i wouldn consider the james for a happy medium...

I have owned the Sunfire Architectural. There is no comparison to the James. Well, there is, but it is not good for the Sunfire. After living with my James for a couple of months and doing some serious two channel listening: I don't know how I lived with the Sunfire. I don't know about home theatre, but let's face it, I had to see how the James did with the Gladiator sound track. Unbelievable. Prodigious, taut, air moving bass of an order I didn't hear in my Sunfire. I had no sub woofer referrent with my Sunfire, so my ears were a bit ignorant. The Sunfire: playing complex bass runs is distortion city compared to the James. If you got the $$, go for the James. It'll bring you home.....

No brainer - Revel B15 (or B 30).
You don't have to worry about placement as you have an EQ built in, and the output is outrageous.

Actually, I am buying the Sunfire true sub EQ. I can't remember, does the architectural Sunfire have the Equalization system like the Eq series?
