    I have a pair of DPL12 based subs (18x18x24, sealed) that I am very pleased with. I have played around with many, many positions and it has been very educational... thanks to all who have brought me this far (especially Jack G...).

    Now... I am debating turning these into downfiring subs. The cabinets are very nice and I am very leary of, say, putting in some threaded anchors and adding some 4" legs. Any suggestions for a non-intrusive way to make them down firing? I was thinking of building a frame and putting them into the frame... with worst case some form of shim or "stiction device" (tm) so they do not rock.. any better suggestions?

    FYI... I am aware the DPL12 is borderline for down-firing. I am willing to go ahead and try this anyway (I believe Adire said I would lose on the order of .25db.. and beyond that they did not see any problem with it).
