All great products, some with more history than others. Of course PSA is actually a rebirth of "old" SVS persons. So, both companies have benefitted from great minds. Many of the makers talked about on AVS have reputable warranty and product support. I've personally got a pair of Ultras (PB) and have loved them over several years, except the BASH amp failures. But those got upgraded to Sledge amps and are even better.
As far as bashing those prior opinions of "overall" better parts and finish, it's rather comical. It's HIS/HER opinion from their observation on the outside of the box likely. No further indication of tearing in was mentioned, so take it for what it is - a basic opinion. Man, this place has gotten touchy again.
I've not seen a PSA in person, but from interweb pics, I might agree with that poster that in general the SVS "seems" to ME a slightly better product. I make this based on the amp for one... SVS has balanced inputs and the PSA doesn't. Not a huge issue for most, but it is for me. This is a simple eye test to me as to the assumed amp quality - nothing scientific, just a statistical probability - more higher end amps have balanced ins and more entry level amps don't - but this isn't a guarantee in this case either. Now, PSA's triple triangular unit does have balanced ins, so there's that option. The speaker driver also is more robust in the SVS, again just a visual eye test. Of course there are plenty of car audio over-the-top subs that look fantastic but are crap. So, just because the basket is killer built, doesn't mean the driver will provide lower distortion, flatter response, more output, longer life, etc.
The PSA finish options are wonderful - something SVS has dropped in recent years. That's too bad. That's what almost pushed me to try a PSA, if it wasn't for the lack of balanced inputs. The natural wood finishes are a special touch in a piece of furniture that most of us have sitting in our living rooms, not a dedicated separate room. Of course the gloss of SVS is nice too, but it's like the Model-T car - "You can have any color you want, as long as it's black."
Beyond that, both units look impressive and with free in-home auditions possible, it's easy to compare visually and audibly in person! Glad we have these great options from great builders and companies. Otherwise we could be buying B&M store units and have to be satisfied with 30Hz extensions.
Why do all of my threads suck? Is there an internet posting school somewhere? -wes k
