Hsu VTF-15H Subwoofer HT Labs Measures

HT Labs Measures

This graph shows the quasi-anechoic (employing close-miking) frequency response of the VTF-15H subwoofer with one port open (blue trace) and with both ports sealed (red trace). In both cases, the Operating Mode switch was set to EQ1 and the Q Control was set to maximum.

The VTF-15H’s close-miked response with one port open, normalized to the level at 80 hertz, indicates that the lower –3-decibel point is at 24 Hz and the –6-dB point is at 18 Hz. The upper –3-dB point is at 162 Hz with the Crossover switch set to Out.

The VTF-15H’s close-miked response with both ports sealed, normalized to the level at 80 Hz, indicates that the lower –3-dB point is at 27 Hz and the –6-dB point is at 20 Hz. The upper –3-dB point is at 165 Hz with the Crossover switch set to Out.—MJP

Thanks for the review. I had asked for some online only sub reviews when Rob Sabin came on board. You guys delivered. Thanks for introducing the audience to a great bang for the buck product!

I considered the HSU when I was upgrading, but couldn't quite fit it into my space. I had to go with the Epic Empire. I love the Empire, but really appreciate the professional review of the HSU.

I love the high end stuff like the JL Audio F113, and would love to own one. However, the HSU lines up with my budget. The JL is about $3600 plus tax which (with my shoes off for counting) equals about 4 HSU subs. If you have heard this product... How would you quantify the differences and how would that change if you had one JL versus 1 HSU in each corner? I'm not asking for a shoot out of which is better, just differences in sound and setup. Thanks.

Good Evening. I'm an average listener of audio equipment and love sound. I just finished reading about the Epik EMPIRE subwoofer. IT has two 15"woofers inside it's cabinet. Here's the strange thing about this sub. I have found two reviews for this sub so far and the reviews were very good to oustanding. It's obvious that everytime i read about some sub that can go as low or loud as HSU VTF-15H i lose my mind.Ha,ha,ha. However, i still love and prefer the mighty HSU REASEARCH VTF-15H subwoofer for it's price and capabilities. I wonder what i'll read next? Hey, wait a minute. i just realized that a gentleman who's comment appears above mine has an EPIK EMPIRE subwoofer. Matt. Does The EPIK EMPIRE subwoofer go as low? 15hz? Or play as loud?
