    I am planning on building a "Home-made" SVS with an Shiva Mk III and a 250 Watt amp from parts express. I'd buy the SVS, but im short on cash, and what ill spend making this sub is still streching my small budget. I've been readin up here these past few days and still wonder what an SVS looks like inside. Are all the ports the same lenght? How much polyfill(if any) does it have? If anyone has taken apart their SVS and would like to share their findings I would be most grateful. Pictures would be awesome. Thanks in advance.

    What you're looking to make is a tube sub...these were around long before there was an SVS. Check out the "Sonotube project links" at the top of the page for many details on construction.

    Heck, you can even try buying one of the original SVS 12" drivers off someone who's upgraded to the new driver (look in the Hardware For Sale area on a regular basis) if you wanted to duplicate the older SVS models.

    As Patrick mentioned this would be the cheapest route no doubt. The first original SVS drivers come up for sale pretty often. Cost normaly runs around 45 to 55.00 plus shipping.
    I bought 2 at 45.00 per driver and 2 at 50.00 per driver plus shipping. This was last year.

    You could then just clone the size you want of the original powered single 4" flared port SVS.
    I did this with one of my SVS drivers (2039) and it looks and sounds great.

    Wall lining:
    The "originals" had 1-1/2" egg style acoustic foam on the inside walls.
    This has changed with the newer models. I used the 1-1/2" egg foam.

    The used SVS driver should certainly be cheaper than buying a new Shiva for what ever type project you go after.

    Regards

    Deepak,

    I have a pair of original SVS drivers that I'm looking to ship out. They work really well and I've enjoyed having them. But recently...well, it's time for me to move on. Feel free to email me if you're interested. [​IMG]

    Regards,

    Hey Dan,
    Will you please email me at [email protected] I tried sending you an email about your SVS original drivers, but it was returned to me saying that there was a failure in the delivery.

    Where did you get this info from?

    Reason why I thought they always used R-13 fibergalss insulation from the start.
    Anyway here are some pics of SVS subs.

    This is one the original "first powered" 2039's from SVS. I probley got the wrong model #! The 2039 part (is definitly right).
    A close friend has it. It's got a single port, has a SVS built in amp, and has grey egg crate foam on the inside wall.

    Alright guys, im almost done with my sonosub, but I have two more questions. When stuffing the sub with polyfill, should I fill it completely so it would be 1 lbs. of polyfill per 1 ft^2 of space, or just the sides? And the second, what amp should I buy? I was thiking of the Rythmik Audio one thats gotten soem talk lately, but im still unsure about which one. Thanks.
