One of my biggest regrets is that I rarely get to compare anything I've designed, since the cabinet and drivers go back to the owner when I'm finished. I've only heard the HT3 a couple of times since it was introduced, and in those cases I hadn't focused on the bass response. Recently, however, Jim sent me a damaged cabinet and the TC sounds woofer so I would have something to experiment with if we ever decide to change anything. Today I took some annual leave to compare 10" woofers in an attempt to find a replacement for the Peerless unit used in my MB0W1 3-way. It's been discontinued in some mindless corporate move by the parent company. I've measured and listened to 3 or 4 possibilities in the under-$100 category, and thought a couple were doing pretty well. Then, for fun, I hooked up the HT3 and did a tone sweep with it and the most promising 10" I've found to date. Now the TC 10" costs twice as much, but we're not talking diminishing returns here. I thought I was getting some decent output at 32 Hz from a Peerless, but when I switched to the TC, the whole room started to shake. And I could play it at almost twice the drive level before distortion started to take over. The TC held up to 28 Hz with no strain (but with some very worried looking dogs), at which point the other 10" had been reduced to flapping. I make my living going after deceptive advertising, and I expect hype in any ad, but I must say the TC people really deliver on their claims.
