    Since I've seen a few used SVS drivers come up on the market I was wondering how does the old SVS PC driver compare to say the Shiva?

    Does SVS provide the TS parameters to build a DIY sub with the old driver?

    Anyone with info that could help me out, it would be greatly appreciated!

    Thanks,
    Troy

    I built my DIY with an old SVS driver, and in the discussions around it I discovered that people generally used / recommended the Shiva's TS paramaters. "Comfortably close" is how it was described.

    I don't know how far off they need to be before they are considered a different animal.

    My sub is an 88l vented, from Adire's plans for the Shiva, and I get very good results down into the low 20's. It sounds better sealed, however. The difference is noticeable mostly in music, and the diff is subtle. I don't know if it's due to using a driver other than a Shiva in a Shiva alignment or the diff between sealed and vented.

    I bought that second driver with the intent of making 2 sealed boxes.

    Good Luck!

    Thanks for the info Colin!

    I'm not sure what I'll do. My little apartment doesn't have room for my little Polk sub let alone an EBS shiva or SVS, so we'll see what the wife says...

    Thanks again!

    But for the price of a used SVS driver ($40-$50), the performance is mighty nice!

    That matches the parameters stored in my WINisd file.

    I just rec'd that pipe organ CD offered on the Sound and Vision forum, shook the house just fine. Not bad for what is considered the least capable driver SVS has ever offered.

    Simulated next to the Shiva, they match almost perfectly, but the SVS has a smaller Vas, 130 vs 150l.

    Thanks for the info guys!

    So would the design for the EBS Shiva work well with the SVS driver?

    Thanks,
    Troy

    Yep - very well.
    Almost identical, the Shiva actually shows a higher port velocity.

    My software may be old, etc., but the 2 drivers follow nearly the same curve.

    No reason not to try it. 142.5l box, 17.25" x 4" port.
