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?

I've been looking at subs, especially those that can play the very lowest organ notes found in the Saint-Saens Symphony No. 3. I think this one call pull it off, and I'm VERY excited!

Thanks for your help, Soundandvision!
