HT subwoofers

REL Studio, Sentor or Stadium go pretty low. I do not know if doing 5hz cleanly is possible.

I suspect that this is a physical impossibility with anything small enough to fit in your house. Also think of the power requirements. As I recall, my Yamaha C2a had an infrasonic filter that rolled off anything below 15hz. Hard to imagine that there's any info down that low.

hsu tn1220 is very musical, but also kicks ass on home theater. check out hsuresearch.com. hsu also makes a model VTF-2 that gets great reviews and is only $499, but i've never heard it. good luck.

Another excellent choice for home theater or music is the discontinued Genesis 900 or the newer 928 (not as good as the older one).
