[sdiy] semi ot: loud speaker for synths

[Peter Grenader]

Czech, listen, I have Bob Diamond's email address (founder of Diamond Audio.
later with M&K, now with Cervin Vega). He can tell you the optimum cabinet
design if you want to do it yourself.  Contact me off list for that address.

Absolutely correct -18's are total overkill.  I think you've guys have seen
that I worked at M&K for three or so years.  Now remember - they invented
the dedicated powered sub (1973), so I assume they know something about how
they work.

They don't make anything larger than dual 12s, and the second one is in
push-pull formation - meaning you don't hear it, it's mounted FACING INTO
THE CABINET and is purposely out of phase with the other (this serves to
push and pull the audible driver from the inside.  A more efficient method
of what a port attempts to do).

You should be fine with 12s, even 10s if the amp isn't one of those $26
dollar Sanyo jobs that Genelec uses for their low end subs.  Those things
suck.
