All of the other reviewers of this sub claim "high output and low distortion." In my room I do not detect a large amount of distortion. If these subs would have the distortion you believe they have then my wife would have no part of them being in my family room. Instead, she now uses the system more then she use to when I only had the Velodynes.
It appears to me that you are trying hard to talk yourself out of the ULS-15 DD because you live in Canada. That is understandable. I would be hesitant also.
Good luck in your research.
Honestly, if I could simply purchase them and return them if I found they didn't perform as well as I thought they would "free of shipping", then I'd likely do it.
But all I can find is objective data/opinions on the sub, and I'm not one to simply take what a manufacturer tells me without a grain (or several) of salt. Heck, if I did that I'd have a Bose surround system.
I.e., as I do more and more research into subs I simply can't see how the HSU would outperform the PB13 in sealed mode. But one poster does comment "I would expect the ULS-15 to have much greater performance in every respect to a sealed PB13". Or how duals would compare favorably to a single Seaton. Again, both could be true, but without subjective data, for me spending $3k on a few comments that aren't backed by measurements showing CEA2010 limits, GP Measurements/THD, etc. Owner comments all sound great, but I haven't seen any comments from people going from a F113 to a ULS15 or a PB13 to a ULS15 (or vice versa). Pete did email me and mentioned that the sub could do 20hz at 100db at 5% distortion in "their demo room".
I still recall when I tried my brothers old Mirage 12" 150 watt amp sub in my room I thought it was great. Then I went to a Mirage OM200 (dual 8") and thought it was incredible and tough to do better and most reviews I mentioned how incredibly low distortion it put out (never really mentioning what SPL/frequencies, etc), and then went to a PB13 which again was a huge step over the OM200 and I further understood what "low distortion" meant vs. "low distorion at very low frequencies at high SPLs" and this time it was actually backed up by subjective data. Just want to make sure I'm not taking a step backward and spending CDN$3k or more in doing so.
In any event, I feel like I'm hijacking the thread and don't want to detract it any further. Just wish all manufacturers would have the guts to send their woofs to a common testing facility (anechoic chamber perhaps) for testing and provide that data as my guess is they all do it anyhow. But then, none of them do.
Maybe forums like this just cause more paranoia with all HT purchases than they're worth. I recall going through the same thing when I was debating the PB13 vs. the HO vs. whatever else I was looking at at the time!! Stupid AVS.
