VTF-1 Subwoofer

  More views:

With our new models, we have given you unprecedented performance to cost ratios! This is a slightly lower powered version of the VTF-2 Mk 2, 200W instead of 250W (which translates into a 1/2 dB difference, not perceptable), but still packs more power than the original VTF-2.

If history is any guide, your system will sound remarkably better with the VTF-1. Usually, the reactions are the same. Those new to subwoofers exclaim that the VTF-1 has reawakened their music collection with new layers of sound. Owners of lesser subwoofers remark that their featureless boom is replaced with tight, enjoyable notes and textures. Experienced listeners are surprised by the VTF-1's impressive bang for the buck. You would think we would get used to the compliments, but we always appreciate them.

Studio-quality bass has traditionally been out of reach for the masses. Try this star performer that changes that.

Harnessing the unique Variable Tuning Frequency port technology (VTF), each port uses the air generated from the long throw woofer to dramatically boost the deeper frequencies. With both ports open, the VTF-1 doesn't seem small anymore. Both ports are large, with enormous flares to virtually eliminate port noise and distortion. This kind of port design is extremely tricky to engineer, and the VTF-1 succeeds down to a very deep 25 Hz with one port open (in maximum extension mode).

The reason for variable tuning is that all subwoofer designs, especially consumer-level subwoofers, involve tradeoffs in design. You cannot have a small subwoofer that goes very low, plays very loud and costs very little. Traditionally, the engineer decides what tradeoff he or she thinks is best for the consumer. The consumer has to take it or leave it.

The VTF-1 changes all that. It allows you, the user, to choose the tradeoff. If you enjoy music that is loud but does not have much deep bass, set the VTF series for maximum output. That way, you get maximum dynamic range with the lowest distortion. If you like music with deep bass, set it for maximum bass extension to reproduce the deep bass accurately. You can even switch between the two modes depending on what you play. That means effectively you get a subwoofer that can play loudly, and can play low, all in one, at a reasonable price!

Industry Reviews

The VTF-1 is an improved version of the VTF-2 that the following magazines raved about:

"On a per-dollar basis, direct from the factory, the VTF-2 is the best subwoofer known to me."

Peter Aczel, Audio Critic Magazine

"made my jaw drop....the overall performance of the VTF-2 (in the 25Hz tuning configuration) could be reasonably compared to the performance of the $3,000 B&W ASW 4000....a performance benchmark to which other under-$1,000 subwoofers must be compared."
Richard Hardesty, Widescreen Review Subwoofer Buyer's Guide

Reviewer's Choice Award 2000
Sound & Vision

"...may be the best-bang-for the buck "true" subwoofer you can buy."
Howard Ferstler, The Sensible Sound

Best performer in a comparison test.
Tom Nousaine, Sound & Vision

"[A] best buy in subwooferdom."
Robert Deutsch, Stereophile Guide to Home Theater

"...if you're looking for more bounce from your audio bucks, the Hsu Research VTF-2 powered sub has no equal."
Steve Guttenberg, Audio

"awe-inspiring...I enjoyed more soundstage depth, more thereness, more realism. This spoke louder about the VTF-2's bass quality and inherently low distortion than thunderous SPL output levels (of which, incidentally, it is also quite capable)...a sure-fire recommendation for anyone who has superior monitors or even tower speakers and wants to add quality and quantity bass."
