SVS PB12-Ultra/2 -vs Velodyne DSL5000R Had a blast with the two subwoofers for a couple of hours. Finally getting RoomEQWizard running on my laptop, It was really cool watching the sweep extend strong down to 16hz on the SVS for sure. The DLS5000R was no slouch, the curves looked very similar except the Velodyne had the same output at 20hz that the SVS had at 16hz. Even on all out demand the subs seemed more similar than different. Both provided easily 110db on over all output from 20hz to 80hz. Both come with 1000 wat amps. I didn't see much need to go beyond these levels even though both subs sure seemed like they were not really breaking a sweat at these substancial levels. We used the big metal ball drop scene from Fight Club for the real world shootout. Both subs running at the same time, one in each front coner of the theater we hit an amazing 117db with an around reference level running on the system even recalibrated for the dual subs. The SVS hit 109db to 110db by itself, the Velodyne hit around 108db to 109db on the same scene, same volume level by itself. The Velodyne seemed to actually have a tad more impact during some parts of some audition scenes, we both agreed with this. The SVS just stays nice and flat and silky smooth if you can actually say such a thing about a giant power house sub that is rocking your world with bass. Both subs were extremely impressive by themselves, and pure sub heaven running together, I have to admit I have really come full circle on the dual sub debate, and once again find myself liking duals more in general over any single sub solution. While the test didn't make me an SVS convert especially given the budget difference, the SVS did show why it is still a way bargain in the Subs that can actually reproduce 16hz arena, the Velodyne sure showed why it is still king in the under $600 arena as well. It was fun, the SVS sub was giant compared to the Velodyne sub in physical size. But what a fun way to spend a Sunday morning. And Todd you have a really beautiful theater there. If you haven't posted pics of your theater on here, you sure should, others would love to see it.
