By the way, there was a white SVS SB-3000 which really is a killer sub, but sadly that version was only released in Europe. A sealed sub that can dig down to 20 Hz with some real oomph is the SVS SB16-Ultra. A really good sealed sub for deep bass, but alas it is not available in white. JTR used to offer their subs in automotive finishes, and the RS1 would be absolutely bonkers in deep bass, but that would probably be well over $3k in a gloss white if they even offer that anymore. It would have many times the performance of some Rythmik 12"s though.
