New models

[Rob Babcock]

I almost hate to even ask, as the TN series are incredible subs, but is there any plan to create a larger sub model? Just curious. I've been very happy with my pair of TN 1220's & 500 W amp, and I can't say that I've ever needed more (even so, I did buy another 500 W amp used with the idea of adding a 2nd pair of 1220's down the road! Hey, if some is good, then more is better, and too much is just right!).

But, rust never sleeps, so they say, and there are other companies making some nice (tube type) subs, some of them a bit larger than the biggest Hsu offering. Now the main competitor in this area makes subs that most people don't find to be as musical as the TN-1220s, but are highly regarded for HT, but that begs the question: have you considered a "HSU Magnum" sub? You could combine that tight fast, slightly overdamped bass quality with an even large enclosure.

While I'm rambling, any thoughts of a model with a more high end visual appeal? I know it wouldn't be cheap, but how about an aluminum cylinder? It would be very strong, non- hygroscopic, and it could be finished/painted in a variety of ways (eg, faux marble, wood, Corvette body paint!). I realize this isn't very likely, but I recall that at one time you manufactured a cost-no-object bass system that was incredibly expensive but absolutely unbelievable from a performance standpoint.

Anyway, thanks for listening.

No plans to come up with a bigger model. First, big subs are a pain to ship. Second, we like the concept of building upon what you already purchased. A bank of TN1220HOs can do wonders and do not intrude too much into the room. All you have to do is to hang a curtain a little over a foot out from the front wall and you can have a large number of 1220HOs behind it that would literally blow out your windows and yet remains invisible. The beauty is that you can improve your system without obsoleting what you already purchased!

An alimunum tube will be a lot more resonant than what we are using now.

Thanks, Dr. Hsu. I was afraid you were gonna say that! Your right, of course; it does make sense to build upon what you have, and shipping would be a major bear. And I realize aluminum would be more for durability/image than performance (though I thing Gallo gets the aluminum enclosure really "dead" by rubberizing the inside. Guess that'd be pretty steep for a big cylinder!).

On the same subject, I take it that adding another pair of subs to my current pair of TN-1220's would work well? I plan to put one pair + 500 amp in the front of the room and another pair + 500 in back. Each pair would be hooked up to a parametric amp eq'd just for that pair. Does this sound like a plan? Granted, it'll be a little while; I get great enough bass with two that another two is a luxury that'll have to wait for a couple other upgrades that are more pressing.

Thanks for your time.

Adding another pair to your current pair should work very well, although I am not sure about placing them in the back versus in the front with the other pair.

The spot with the current pair might not be large enough to accomodate 4! But of course it would be a good spot.

I've been told by some other designers that front & rear subs out of phase is often a good setup. I would of course do some experimenting to determine the best location. It's a bit academic for now, as I won't likely be able to go for another pair for at least 6 months.
