    A new subwoofer project coming up very soon.

    Based around a 10" (or maybe 12" if we can fit it in, size and cost wise) driver this will be for Taz himself when my RTP-15 leaves him.

    It's designed to fit within his TV stand featured here.

    This will be the RTP-X.

    Look for more info and designs soon.

    The RTP-X will be using a Peerless XLS-10 driver, inside an enclosure of approximately 1 cubic foot, around 17/18 litres. This will be made from 22mm MDF, with a 30mm MDF front baffle.

    There will be some form of grill fitted to the front is required, and spikes or rubber feet will be fitted to the base, for use with Taz's stand or on a carpet.

    The amplification to be used has yet to be confirmed, but will most probably be a BKElec BSB 100/8, delivering 100w RMS into the 8ohm driver.

    Where's the best place for MDF exceeding the standard 18mm available at DIY stores?

    Small design change. Concerning the front baffle.

    The parts have all been cut as I type and they are undergoing the veneer process.

    So why the change? If it's going in Taz's TV stand the sides
    wouldn't show or would they? Just curious.

    To make it future proof... No one would want to buy it 2nd hand if it had edges of mdf showing against such a lovely veneer. And I may at some stage change my TV rack so it needs to look nice if it is ever on show.


    Mike: Sorry, no idea on buying MDF, builders merchants or your local furniture factory may be able to help.

    Fair point Taz. After all you and Retro seem to be churning these things out at a rate of knots
    Mike, look in yellow pages for timber merchants, that's where I got mine.

    Mike,

    Have a look here http://www.laver.co.uk/

    You can buy MDF sheets up to 60mm thick :)

    That would make a really rigid Sub cabinet :D

    They also do 8x5 sheets as well as the usual 8x4 size.

    Sure I have seen veneered MDF on there before, cannot find it now though.......


    Mark.

    Have you bought the driver and amp yet?

    BK are doing a package deal on the XLS10 and BSB200, which you might as well go for as it works out to only slightly more than if you buy a BSB100 separately: http://www.bkelec.com/diy/xls10.htm

    In a 1ft cu. enclosure the combo really performs!

    MuFu.

    Is the cab joined only with glue or have you used screws?
