First impression: BIG. The shipping box is bigger than expected, and is just at the point where it is awkward to carry, especially up stairs. When I pulled the sub out, it seemed quite large, but with the VTF-2 along side it, it actually was not as big as it seemed. Larger only by about 20%. Weight felt pretty close and the VTF-2 cabinet feels a tiny bit more solid, likely due to the smaller size. The finish on the PB-10 feels nicer and is more appealing than the VTF-2. Those with CRT based TVs will need to keep this thing a decent distance away. At about 3 feet away, it was still discoloring my screen, and required me to move them further apart. Initial impressions after 2hrs are somewhat mixed. Popped in SW:AOTC, opening scene and was not exactly floored. Infrasonics are definitely more noticeable and tactile. The difference between the VTF-2 and the PB-10 is not as large as I expected and is actually rather subtle. Output seems about the same, and the bass peak limiter on my receiver topped out about the same spot, at which point I could hear the PB-10 doing what sounded like some limiting of it's own (levels at which the sub will likely never reach). Toy Story 2 - opening scene; again better, but not shockingly better than the VTF-2. Good feel to the title passing over and the door opening. Says something about the VTF-2's ability that it was similar in output. Finding Nemo – the submarine sliding scene, the whale exhales, and Darla. There was noticeably more low information in all of these scenes. Lots of stuff in the room was vibrating. I tried some music with low stuff. Here the difference was more noticeable through it's range. The PB-10 was cleaner and smoother overall, and took on more of a support role without drawing attention to itself at all. Very nice. Dinner break and back to movies, next being Titan:AE DTS. Earth destroyed / moon shatter very impressive, but it was the ice field scene that really wowed me for the first time with this sub. I have not experienced this scene like this before. The VTF-2 did a decent job with it, but the PB-10 shows what it’s made of here. Also tried: Jin Roh – in the sewer, The Haunting DTS ES “coming mother”, various music tracks. Next I will have to sit through an entire movie and spend a little more time with it. Movie night will be at my place on Fri More later after I've had more time to play with this thing. I will likely play around with it’s position this weekend to see what I come up with, but so far I am not disappointed with it at all. Price vs performance is nothing short of amazing. Hats off to the guys at SVS!
