Dave Upton (Home Theater Forum) spent some with our flagship subwoofer, the T-18. Click the Home Theater Forum logo to read his impressions of what he calls, "the best value in high end subwoofers."
" it was obvious that the T-18 could handle ultra-pressurizing subsonic content with ease as well as deliver a huge amount of impact. Turning the volume anywhere close to reference level had my room rattling in ways I never thought possible. Even with such impressive output capacity, the T-18 was remarkably dynamic also, delivering intense bass without being rude about it."
"With the T-18 properly dialed in, the experience was the most intense home theater bass reproduction I’ve ever encountered from a non-DIY sub."
Now after a few days with this sub I am very pleased and impressed, which is saying a lot because I have been jaded over the years at work being able play with a lot of hi end gear and also having the privilege of owning and or being able to use quite a few world class subwoofers at one point or another through the years in my ever changing upgrade sickness ....ie... (rel studio III, focal sub utopia, jl f113 x4, m&k 5000) most of which have been experienced in my home which are all very very good subs.
Musically I still feel imo the rel so far the undisputed champion in that category, now the t-18 isn't bad at all in that regard with some careful setup. Now for HT duties this thing is ridiculous it some how managed to smash my reference point for what a big sub or even multiple subs could do in my room. With that said I have now experienced rattles and noises in my house I have never herd before and I like to crank my system from time to time.
The tipping point for me deciding on PSA besides the t-18 being a good match for what I needed it to do, it would have to be Tom's amazing customer service and support was my deal closer. It's clear that Tom suffers work o holic syndrome because he seems to always be available. In the end I am very happy to have found PSA! And have definitely found a new respect for the small guys in the sub industry most if not all the companies I have seen lately have a value / sound / output ratio that the likes of 90% of the big hi end speaker companies have anything to compete let alone if they do be ready to pay 10k or more for it. To all those small companies I say Bravo!

Thank you very much for your incredible subwoofer!
I receive your PSA T18HT last Friday and compare it with the Velodyne DD18.
It sounds like the Velodyne is only a midrange bass compare to the T18HT!
The room size is very large (I can increase the room size from 300 to 570 square feet) that's why I have a peakt at 8Hz...I've never feel the extreme low frequencies with the Velodyne...but now the T18HT goes down to the deepest frequencies!
It sounds like there is a complete other sound system...not too much midrange bass and lot of subsonic frequencies.
Some movies change the atmosphere because of the wider subsonic frequencie range ;-)
WOW... I'm realy overwhelmed!
Thank you again for your support and your fantastic product!
