View attachment 12315One PSA Triax has more output than dual XV30Fs stacked and even separated, I also believe it has the equivilent output of 3 XS30s, for your room I would definetely call Tom or Jim and they will tell you exactly what you need, I would go out on a limb and say to start with dual XS30s or XV30Fs, they could pressurizi that 3300cf space quite nicely, that's pretty close to my space and I had dual XV15s do quite well in my space, the XS30s also had no problem filling that space with plenty of headroom to spare, these subs are monsters, I can't wait on my Triax (one of these will do the trick for you also) duals would be insane, I am considering a second but I am a pig. I'm chatting with my man Alex (Fuzz) about doing some DIY kits for mains with big drivers, I just can't help myself with big stuff

, that's the same reaction I get from my wife

. Go with as much as you can afford, to me it's never enough, but like I said I'm

If you don't mind moving a 200 ilb. subwoofer around I would seriously consider the Triax, here's mine waiting for drivers.
Call Tom and Jim and talk it over with them or email them
