For people who think that SVS is the only cheaper option to get a high quality subwoofer, this might be of interest: Rocket Loudspeakers UFW-10 Subwoofer This subwoofer goes less deep, and plays a bit less loud than what SVS offers, but: - it offers high WAF (!) - it's very small (33cm^3, or 13inch^3) - it is cheap ($599, without transport) - it's fast and musical (according to this reviewer for music it performs equally well as a PB2+!) - it has a parametric equalizer This is one impressive sub! Just like SVS they ship world-wide, which will be cheaper considering it weighs less and is much smaller. A bigger model (dual-12inch, around $1500) has been announced, coming to the market later in the year.
