They didn't stop making the sub I have (PSA XV15) they only upgraded it, thus the "se" which is a slightly improved driver and amplifier. They were pretty modest upgrades (unfortunately I bought mine a few months before they upgraded and I wasn't eligible to do the discounted swap out of the driver and amp).
It is very true that the "Satin Black Texture" that the PSA comes in doesn't look as good as the SVS subwoofers with their upgraded "black grain vinyl" material. The reason PSA decided to offer their subs with the Satin Black Texture is completely due to costs. If you think about it they did the right thing because it's allowing people that are going to stuff their subs in a corner or behind a couch anyway to get an awesome, giant sub, for significantly cheaper than the competition. If SVS opted to do the same thing than their subs should consequently be cheaper... If you were to compare apples to apples (as far as XV15 to PB2000) than the XV would cost $1249 (with the black ash) and the PB would continue to cost $799 (black grain vinyl which ultimately looks very similar). Essentially, you get what you pay for with a PSA
Again, one of the main reasons why I went with PSA was not only the startling reviews but the fact they are made here in the states and that is still kind of important to me. Also, their customer service sealed the deal for me as stated. Lastly, I read somewhere that the PSA folks had some affiliation with SVS at one point in time (I cannot remember what...)
