Fair enough. I couldn't work this curiosity out in my mind and ended up messing with a bucket and the tub -- flowing it over a dampened side helps some but really limits effectiveness since you want the waves, so maybe an oversized dump bucket to keep high flow? I would think dampening all sides will help a little but not much. Quiet will be a good challenge for someone leaving ATS
in a living space, not dedicated room, I'm guessing. JProx and Green -- I'm interested in what you guys come up with, though I doubt I'm building one.
Anyway, just a thought. Cool pics, ashdavid.
