Anyone out there used the RS270S-8 10'' as a sub?
Am planning to use two of them for my ML TQWT units and would welcome comments regarding their performance.

I am going to use a sealed enclosure for this project. The Quatro models at a -3db of 72hz, while the RS270 goes down to 52hz with a -6db point of 40hz, plenty low enough for my listening tastes. The difference in efficiency is not a problem.

Getting good low frequency output level out of 15 inch drivers is difficult and I haven't tried with anything smaller. I do like Dayton drivers and you're likely to get your expected results with the model you've chosen.

The "pro audio" term has become confused over the years, so I'm not sure what you mean. When I talk about difficulty getting good acoustic level out of 15 inch drivers, I'm talking about the bottom half octave of an organ's 32 foot stops. That would be Coo to Foo -- or 16 Hz to 24 Hz or so. Moving enough air down there takes good complex cabinet design and efficient drivers especially if I'm trying to get the pews vibrating in a cathedal.
Given that 40Hz is adequate bass response for the person asking the original question here, I'd say the term "sub-woofer" is also unclear.
I guess the term "subwoofer" means different things to different people. I have always thought of a subwoofer as a driver reproducing frequencies from 100 hz down to whatever lower range you would be designing for. In my case 40hz is fine.

aosone, why dont you just get organ pipes that go down that low.... It probably wouldnt be an incredible amount more expensive than the subs of the same magnitude.

Hahaha... Pricewise, they're a lot more expensive than you think, and I haven't priced them in about 15 years. And then there is the problem of where to put them without doing violence to the building. They've been adding electronic pedal stops to pipe organs for 50 years either because of cost or because there wasn't room for a dozen 32 foot long pipes and the plumbing to support them.
Hmmm, I was under the impression that some pipe organs could go down to 16hz and below with a fairly high SPL. Now fairly high SPL is where I thought wrong I suppose. I was thinking maybe 130db @ 1meter from the opening of the pipe for a large church and a large pipe organ. Now for a subwoofer that can do that.... it would cost at least 5 thousand dollars.
But I cant see why you havent upgraded to the real thing... 16hz pipes are HUGE!
If you want the pews to shake, maybe tactile transduces would work!

I want my 8.2 Hz pipe, I think there's only one in the world, I'll have the number two. I think it's around 64 feet long.

There's been an organ or three with a 64 foot stop. Low C would be about 8 Hz. You can also get a 64 foot pitch by capping a 32 foot pipe. I've often thought of what it would sound like to hollow out some of white spruce up in Acadia on the coast of Maine and waiting for a good nor'easter.
