I have that issue in my hands right now, 3db (after reading your post, I dug it out; the shootout runs Oct & Nov '03). The Totem was ranked very highly. However, I think your memory is a bit off; no SVS or Hsu subs were included in the shootout. Perhaps you're confusing them with the cylindrical sub from Adire, the Sadhara. They do look a lot alike. At any rate, the author, Keith Yates, concluded that of the models in the shootout, his choice would be a pair of subs: 2 of the Totems or Triads if he could afford it, 2 JBLs or Adire Sadharas after that. [I'd also interject that the Totem sub cost $1500 with the base finish; that sum would get you a pair of HSUs best & the 500 Watt amp, or a pair of SVS subs with the amp.]
There are many published reviews of the Hsu & SVS subs, complete with detailed freq plots and waterfall graphs. Their outputs are quite smooth (I'm referring to the tube subs). Having uniform output is the goal, but of course there's going to be a lot of peakiness in a real room regardless.
I have no stake in what anyone buys, and Hsu isn't cutting me a check each month for referrals. I do own Hsu's, so take my words with a grain of salt if you wish. But I can say by the
measurements of all the subs in the S&V and Home Theater tests, neither HSU nor SVS has much to worry about. Sonically I've heard no serious rival to them, but admittedly there's a few others I'd love to try (specifically, the offerings of VMPS).
I think not nearly enough is made of the very low freq response. 25 hz is pretty good, but that's really the beginning point unless your sub is for HT only. It's nice to have really solid output down under 20 hz- it's called a
subwoofer, after all.
Again, there's lots of other great subs out there, and it would be pretty boring if we all had the same gear. I don't mean to quibble over details but I did want to set the record straight as to that particular magazine feature.
