    I just received my SVS and noticed one oddity. Of course I put in Toy Story 2 because I've heard plenty about the low bass frequencies in the beginning(it's all true!).
    The oddity is this: When using the chapter skip function on the DVD remote to skip past the opening trailers, each one produced a low-volume thump from the sub. Several other DVD's did the same. These 'thumps', if you can call them that, were low in volume, and not too low in frequency( I would guess 50-100 Hz).
    I never had this in my previous subs(Hsu VTF-2 and Velo).
    Any explanation would be appreciated. Thanks.

    I would think that this would ultimatly be traced back to the DVD player.
    When you skip a track, the digital stream drops out for a split second....sort of like a layer change, and alot of DVD players (I guess it could actually be the reciever) transfer this drop out as an audible signal (or the receiver amplifies it that way).
    Anyhow, I'd think it's caused by that. The receiver is passing this drop out on to the sub, so you get a pop.
    As for why the SVS does this and your other subs didn't.....I guess no amps are created equal?
    Any other explanations out there?

    James,
    First, congrats on your fine purchase. I just got my 20-39PC about a month ago....
    Just to let you know, the quickest way to get the best help on an SVS question, is to send tech support an e-mail. They will promptly return an answer to you and work diligently on a fix...if there is indeed a challenge.
    That said, what kind of gear are you using (receiver, pre/pro/amp combo, and interconnects)? have you calibrated the sub and speakers yet?
    I know it sounds redundant to ask, but I've found as many others have that the SVS needs much less of a boost from the receiver as other subs. i.e. my Klipsch KSW-15 calibrated correctly on the receiver...the channel level was +5-6db. The 20-39's level is -4-5db.
    That would be a good place to start if you haven't already. Then I'd check that sub cord. If you have a bad connection, this could be the cause.
    But again, send an e-mail to Ron and Tom....they'll get going on a fix for your sub.
    Jeremy

    James,
    Off topic.....which Velo did you replace with the SVS and how significant is the difference between the two. I realize that about 99.9% of the comparisons come out in favor of the SVS but I haven't heard a lot of comaparisons made specifically to Velodyne by people who owned a Velodyne.
    BTW, I have a Velo CT-120 which is an excellent performer, IMO, but of course all the SVS hysteria [​IMG] has me very curious....thanks for any info you can provide.
    Vin

    The Velodyne VA-8110X was the one I had, but the direct SVS replacement was the Hsu VTF-2, which replaced the Velodyne.
    The SVS would walk all over the Velodyne in an A-B comparison (it should, as the Velo has an 8" active, 10" passive), but the upgrade from the Hsu was more incremental in nature. Any disc with REALLY low bass shows up the superiority of the SVS over the Hsu, but with anything over 30 Hz or so the differences are more subtle, but definitely there.
    I would also say that the SVS has more punch at lower volume levels. Overall, it is a more satisfying experience to watch movies with the SVS. At the bone crunching levels I prefer, there is a sense of ease with the SVS.
    I've only had the SVS for several days, so I'll post more of my impressions as they are gathered.
