I live in a loft-condo and my listening room measures 15x20 with 12 ft. high ceilings. The loft is very open, leading to many open rooms and a hallway. Due to placement constraints (has to be near a corner or wall) and the fact that I have neighbours, I've decided on a sealed design vs. a ported one. My music/HT demands are 60/40 - accuracy is required but getting near 20Hz would be nice. I'd get an SVS 25-31 or a HSU VTF-2 in 2 seconds, but living in the Great White North means more than having to endure cold winters - there is a nasty 1.5 exchange rate and 15% taxes to deal with (and brokerage shipping)! So.....my choices are: 1. Adire's Rava ($765 CAD all-in...there is a CAD dealer) 2. B&W ASW650 ($850 + 15% tax = $920 CAD all-in) 3. Mirage OM200 ($1K + CAD...nice, but too much $$$) I am afraid the Rava won't go low enough, even though it seems identical to the B&W in size, 12" driver, etc. The B&W seems to be the whole package: -6dB @ 20Hz. Am I missing and similar designed subs? Any thoughts? PS. Sure, the Paradigm PW2200 seems obvious living in Toronto, but it is just too big (and has a giant port in the back). The Servo-15 is too much $$$! Thanks!
