    What sort of sound would you get if you brought a really good 10" sub made your own box for it, maybe mdf then paired that with a really good mono block amp?

    I'd say pretty good, depending on the driver.

    I have a pair of Adire Tempest 15" drivers in a 16^3 ft box driven by audiophile monoblocs which outperformed my Servo 15's in both sound quality and depth.

    I was looking at couple of the adire maelstrom, 15". in a 150 Litre sealed enclosure and a 1500W mosfet amp with LRC to give 112dB output and 109dB at 20Hz. All very achievable if not expensive.

    Mind you how much would that lot cost commercialy?:eek:

    Are there companies where you can buy subwoofer kits- everything is included- driver, amp, powersupply, crossover, cabinets- but I build it myself?

    ta. Had a look- seem OK, would like a really really good kit though, something to beat a £1000-£2000 retail sub.

    Had a good look at this before buying a Velodyne from eric. I used a search in google and got literally hundreds of hits. The sites tend to be mainly in US and Australia with the UK generally supporting subs in cars. There's everything from design of the cabinets and amps from scratch to kits to assemble yourself.

    There are a couple of good US forums covering DIY speakers of every size and description.

    All interesting stuff, so what about good car subs like JL Audio paired with a good amp.

    Will these really sound as good as a REL or M&K stuff?

    Yup, almost certainly, bass isn't the dark art that everyone thinks it is. Going low, and going loud are simply a matter of driver size and power in a good enclosure. That's all M&K and REL have on their side.

    Beating things like a Martin Logan Descent (Very overlooked sub, but if you see the price you'll understand why) or Velodyne HGS however is a different matter. Also the Paradigm Servo-15 is IMHO the budget king.

    But Velodyne HGS-10, 12 aren't that expensive.

    I mean, consider paying 500-600 for a awesome sub then £1000 for the amp, surely this would eat a pre-built sub for the money.

    If you can find a 1250W (RMS:eek:) amplifier, with output characteristics precisely matched to your driver of choice for under £1000 then tell me where, as I'd love one.

    I've got a lot of respect for DIY sub builders, as they offer a lot more for the money than REL or M&K, but there are engineering problems which most manufacturers won't admit to, if only because of the cost of solving them.

    Hi

    In DIY the possibilities are endless.
    The latest drivers available to the DIY-er are truly at the cutting edge of technology.
    The only limiting factor is the size of your wallet, but that's not saying you can't have a top performer without spending a shed load.


    QSC RMX 2450 750 Watts per side at 4ohms, 1500Watts bridged. £595
    QSC PLX 3402 1100 Watts per side at 4ohms, 2200Watts bridged. £1129
    Or try a search for a second hand Crown K2 or any other quality pro amp.

    Cheers
    Boris

    Thanks Boris, now all I need is the laser accelerometer and the DSP engine, and I'm set! Sadly these are going to cost big bucks:(

    (The above is serious, I have a world beating DIY sub in mind.)

    Boris,
    The accelerometer and DSP are off the shelf, they're just lab equipment. Expensive but buyable. It's the DSP code that's the hard part!
