The SVS PB 13 looks awesome - for movies the ports can be left open and the 20Hz output is outstanding - no compression WOW, however the group delay is a wee bit high for my liking for music (may sound plodding or muddy in kick drum). No worries though - stuffing the ports (changing to sealed) will make it more musical (lowers group delay at the expense of higher cone travel and distortion - but I prefer sealed subs to get a tighter sound which is better on transients).
Actually any of these subs look good on paper...now how will they match to your speakers....that is tough question...only you can tell that.
