    Do forum members do this sort of thing ?

    Chatting to a mate he thinks you'd get a good response by sticking the driver in the wall (although the occupants of the dining room may not appreciate it).

    Alternatively I could put driver in the fireplace. Not sure what it would sound like outside!. What's the biggest drive unit out there? I expect the ICE people have the biggest?

    Then just buy the most powerful old amplifier I can find on eBay. I'm only thinking of .1 channel here.

    Any thoughts?

    Hi Jim, as Ian says have a look in the DIY forum for some superb home built subs. There are some pretty serious bits of kit being built by these guys :thumbsup: I may even finish mine one day :rolleyes:

    Gary G - Thanks for that. I think I might join the cult.

    I don't have 'drywall' but I do have space below the floor boards and the boards have already been hacked about a bit when the central heating was put in, so maybe this beats the chimney (1 driver feels inadequate now I've seen those 4 driver systems).

    Off to DIY section now.

    The chimney may not be a good idea, depending on it's dimensions you may find that you get pipe resonance.

    Other forums that may be helpful:

    If you decide to want to do the job once and do it right then you need to check this out:

    http://www.adireaudio.com/TextPages/ParthenonPageFrameText.htm

    If you want something a little more reasonably priced then this should do the job:

    www.adireaudio.com/TextPages/TumultPageFrameText.htm

    The UK distributor used to be:

    Unfortunately Adire Audio no longer supply dealers, however as I only needed two of them for my sub I have a spare one, brand new and unused in it's box, email me if you're interested.

    So many options, and money is the only restriction. An underfloor Infinite Baffle would be quite labour intensive and is rather 'fixed'. Whereas an 8 foot sonotube would sit nicely in the corner of the room, and would presumably be sellable if I didn't want it anymore.

    GaryG - That tumult looks nice. Compared to the Tempest does the greater travel only show an advantage at higher SPLs ? (I'm new to subs). And go on then - PM me how much you want for the tumult.

    Off o read up on sonotubes now.

    I'm not sure if putting a driver into plasterboard walls would be a good idea! :eek:

    Second paragraph, first post is fairly general. It was the first thought since my house doesn't have any internal brick walls. More to clarify for any casual readers and is an interesting thought in it's own right, just using the house as a giant resonant cabinet!

    Here's some info on Sonotubes:

    No, the Tumult is better at all volumes, with lower distortion and much better sound quality. However, you need to factor in the cost of a powerful decent quality amp to take advantage of the Tumult, along with a low pass crossover.

    I have to be sensible with budget, so I think a Tempest will do me. Although I've just spotted the 18" Maelstrom ($300). I'm in the US in a couple of weeks so might have to find room for one of those in my suitcase on the way home.

    I think it will first be driven by my soon to be retired AV amp (old pioneer vsa730 2x90W direct stereo)

    Hi all

    Here's one I made earlier.

    Actually I borrowed this image from another forum to indicate exactly how big some subs really are. I think this is actually the Velodyne 1812.
