I am doing a big round of subwoofer tests next month
Great! Hope that some REL subs (most interested in S510/S812) will be finally tested too!

Can't you get your house mouse to buy them for you?Since I am buying these all myself, REL subwoofers will not be part of it. If someone wants to send a REL, though…
Power Sound Audio uses pro audio drivers that are really designed to be used more like woofers rather than dedicated home theater subwoofers. They are excursion limited and are better at delivering high SPL in midbass rather than creating thunderous deep bass and ULF effects. They are great for great extremely clean, accurate bass, but run out of steam pretty early compared to real home theater subwoofers with a lot of xmax and lower tuning.
does anyone know what SVS and HSU are using in their competitive models?
I would need to search through my emails but IIRC, I was told by SVS that their speakers are all designed in-house when I specifically asked the question.

I think you're confusing the fact that PSA uses pro audio drivers in their bookshelf and tower speakers, not their subwoofers. PSA subs go much lower than pro audio subs and are specifically designed for home theater use. In fact the top of the line PSA sub (TV42 Ipal with dual 21" woofers and 3,800 watts RMS) is rated for 11 Hz @ -3 dB with in-room extension to 8 Hz.
I'm confident that if you try to come up with data to back up that claim you will fail, but please prove me wrong if you can.
The experience of every user I've seen, and my own, is very much NOT that PSA subwoofers demonstrate the limitations that you claim.

This is the driver that goes into the S1512. It has 16mm of xmax. Not bad, but significantly less than what you'd get with a regular subwoofer. More importantly, look at the specs and parameters of the driver. It has a 4.5" voice coil designed to take a ton of power, which can only be delivered to the driver without bottoming it out at higher frequencies. If you model it in a box, it rolls off very high. B&C even specs it as only going down to 35Hz.
It is a beast of a driver, but it was really intended for a different use than home theater. That isn't to say it can't be used for that application; EQ makes a lot of things possible. I'm just saying that for the price it isn't the best driver for home theater where excursion and low frequency efficiency is sought.

That's the one alright. Tom said so himself. It's also the best pro audio 15 on the market, so one would hope that it's the one.Checking the PSA website I'm not convinced you've got the right driver there actually. It doesn't match the picture you can see in the 'Components' tab of the following page:

As for data, what limit a subwoofer on the low end are the laws of physics. A driver with less excursion simply cannot move as much air as one with more. You can look at all of the CEA measurements done on subwoofers to see that they top out on the low end precisely where they run out of travel. This is true of all subwoofers, so one can predict with perfect confidence how much low end will come from PSA subwoofers just by looking at the specs of the drivers.
