NOOOO dont use the FAQ from Bogus!! it makes way too sense and no one actually reads it anyways!
ok ok, seriously though, before you buy ANY subwoofer, check out
www.realmofexcursion.com or
www.woofervids.com and actually see what some of the subwoofers you are considering look like while actually in action. Theses sites are realitivly new to the audio community for reference, but ive found them invaluable many times since their introduction. I even have a couple of videos on there...(shamelss plug for attention)
