Hsu Research VTF-15H Mk2 Subwoofer

This graph shows the quasi-anechoic (employing close-miking of all woofers) frequency response of the VTF-15H Mk2 subwoofer (blue trace).

The VTF-15H Mk2’s close-miked response, normalized to the level at 80 Hz, indicates that the lower –3dB point is at 16 Hz and the –6dB point is at 14 Hz. The upper –3dB point is at 148 Hz with the one port open, one port blocked, EQ = 1, Q = 0.7, and the Crossover switch set to Out.—MJP

I'm looking into getting dual subwoofers later this year and really like these for their versatility, quality, output and value. I am also looking at the Power Sound Audio XS30se. Any chance you will be reviewing it anytime?

I really want to read a review on the Power Sound Audio XS30se subwoofer. I especially would like to know how it compares to the SVS SB-13 Ultra.

And looking forward to getting the 15H. Fortunately, I can save on shipping (but not tax).

PS, speaking of Pixar - have you listened to The Incredibles? I've always found the sound in that movie to be "incredibly" fun for a surround sound demo.

Purchased this woofer after reading many excellent reviews and I love it! Clue(!!): many reviewers use this for their reference sub! I listen to classical music, classic rock, blues, new age, jazz and I like home theater and this woofer does it all. Nice and tight and not overwhelming or resonant for music but it will shake your seat, floor, and walls with movies. It will still thump with music if the genre calls for it however so don't worry! My listening room is about 12 x 15 w/ a missing side wall as the room extends into the kitchen doubling the space, and I have to use almost the lowest volume setting. It is big, heavy, and not too attractive but for this kind of sound at this price, amazing. Loose items near the edges of shelves may vibrate off and hit the floor!
