Whatta Ya Think About Hsu Research Subwoofers?


I’m in the market to add one or possibly two subwoofers to my stereo set-up.  I would like to spend $1,000 or less per unit, and that puts some of the higher-rated units out of reach.  I came across an ad for Hsu, which I had not heard of before.  I didn’t want a Chinese product and it turns out that Hsu Research is based in California and founded by Dr. Hsu, who has a Ph.D from MIT.  Audio reviewer Steve Gutenberg gave one Hsu product a positive review.  I was wondering if any of you have experience with Hsu and could share your impressions/recommendations with me.

My existing set—up is:  Parasound P5 pre-amp with Parasound A21 amp;  Martin Logan 60XT tower loudspeakers.  Thanks!

You can give Syzygy a look, wireless, great support, almost bullet proof, auto e.q. and won’t break the bank. Good recent reviews.

I use two of the SVS SB-12 NSD subwoofers mentioned above in my main system. They are a discontinued model and can still be had for $400 each. Never a glitch.

big_greg: " If "prodigious amounts of bass is your thing", what difference does it make how you get it, whether it’s speakers or complementing speakers with a subwoofer (or multiple subs)? Even if you just want a "realistic" amount of bass, again, why does it matter how you achieve that? A purpose driven device (the subwoofer) just might be better than one that’s trying to be a jack of all trades (the speaker)."

Hello big_greg,

     The main reason I utilize a 4-sub DBA system in my room is not to have prodigious amounts of bass but to attain the highest quality bass that is sufficiently smooth, fast and detailed to blend in seamlessly with my smooth, fast and detailed Magnepan 3.7i main speakers.
     My pair of 3.7i are 6’x2’x2" dipole 3-way panel speakers produce very high quality smooth, fast and detailed almost full range frequency performance all by themselves in my 23’x16’x8’ room. However, they only have a rated bass extension down to 35 Hz which most people, including myself, would accurately describe as deep bass limited.
     I believe the bass the 3.7is do produce is sufficiently smooth, fast, detailed and, of course, seamlessly integrated with the midrange and treble planar-magnetic drivers that many would not discern a need for external dynamic subs that are notoriously difficult to integrate with planar-magnetic and electrostatic main speakers.
     But I added the Audio Kinesis Debra 4-sub distributed bass array (DBA) system, which is almost identical to the AK Swarm DBA system reviewed on the link attached below, to extend the bass range of the 3.7is down to the audible limit of 20 Hz and improve the deep bass impact, dynamics and realism of music in my room. The AK Debra 4-sub DBA system very successfully achieved this for me while also integrating seamlessly with my main speakers.

     You asked: " Even if you just want a "realistic" amount of bass, again, why does it matter how you achieve that? A purpose driven device (the subwoofer) just might be better than one that’s trying to be a jack of all trades (the speaker)."

     You answered your own question. Typical tower or panel speakers are trying to be jack of all trades. Subs and sub systems, however, are purpose built devices that have the dual benefits of being capable of reproducing bass down to its audible limit of 20 Hz and, more importantly, being capable of being independently positioned in the room to avoid the pitfalls of bass peaks, dips and nulls at the designated listening position in your room.
     Tower and panel speakers are typically positioned in a room and in relation to the designated listening seat to achieve the optimum midrange and treble performance along with maxinizing the imaging and the 3D sound stage illusion effect made possible by 2 channel stereo recordings and the playback through 2 precisely placed stereo speakers.
     This main speakers positioning is very important and enjoyable when done properly but the biggest loser in this normal process is bass performance at the listening seat. The precise positioning of the bass drivers (woofers) in the room and in relation to the listening seat is also very important for good bass performance. But they’ve been totally ignored during the normal process of optimizing the position of the main speakers for midrange, treble and imaging performance at the listening seat.
     Proper positioning of the woofers in the room and in relation to the listening seat has been totally neglected and their positions are usually relegated to positions directly below, and physically attached to in the same cabinet, the midrange and treble drivers. It is highly unlikely that the optimum position of the bass drivers in a room and in relation to the listening seat will be directly below the optimum position of the midrange and treble drivers in a room and in relation to the listening seat.
     What could possibly be the solution to this dilemma since the drivers are all permanently attached to each other in the same cabinet or panel and lack the capacity to be independently positioned for optimum performance?
You guessed it, the most basic solution is adding a single good quality sub that can be independently positioned in the room to supplement the bass already arriving at the listening seat from the main speakers and thereby optimize bass performance at the listening seat.
     Progressive improvements in bass performance quality at the listening seat will be achieved by adding good quality, properly positioned subs to the room. The very obvious and progressive bass quality improvements resulting from adding more properly positioned subs to a room are increases in bass smoothness, speed, detail, impact, dynamics, sense of ease, sound stage openness, size and naturalness along with a seamless quality to the integration to the main speakers.
     There are more details I’d like to describe about why it matters where bass performance quantity and quality improvements come from along with the benefits of multiple subs but I’ll stop here for the sake of brevity.
