The turnoff we see most about PSA is that there are no third party bench tests to quantify their performance. If they sent one out for review to even just 2-3 of the better review sites that do good quality testing, it would go a long way to opening our minds to them more.
When I was shopping for Subs, they and Rythmik were both strongly recommended, but with no evidence to back it up. I struggled with the decision for a bit.
Ultimately, I went with Outlaw x-13s. Great Subs, measured and reviewed well. Would actually work as an end table too.
But I'm not trying to sell you on those. Worth considering if you are game though.
But I've said before, 2 good subs are better than 1 good or great sub, frankly. You have a weird space IIRC, and getting good performance across most of your seating area should come first, unless it really is only 2 of you...
In which case, sell half of that Sofa and get 2 Bigger Subs!
