LONG TERM OUTPUT COMPRESSION
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."
I am a happy new member to the PSA family, so over many weeks of searching for that perfect big sub that fit into the space set aside for it to take on LFE duties on my system. And yes I looked at all the great ID companies out there (jtr,seaton,Ra,sub,) and there are so many good options out there, I went with the PSA T-18 although I had originally ordered a pair of v3600's but after some placement measurements I realized that they had no chance of fitting into the space set aside for where most all subs end up in my room. Kinda glad now being it would of been TOO much of a good thing.
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!

Hi Jim and Tom,
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!
