re: the pic
If fountek ribbon, $118.
24 x $118 = $2832
I don't know what midwoofers they are, but even if you assume they are cheap
at $30 each, = > $1000
At least $4k for parts.
/hehe
If you can sacrifice maybe 5 - 15% in SQ, then make a Dayton/PT2 array
like this one and run it active;

Driver cost is;
16 PT2 tweeters = $400
16 Dayton 6" midwoofers = $432
Driver cost = $832 {cheaper than $4k + }
Get two proamps and digital crossover and it's ownage.
Plan B, save $400 and use cone treated NSB's ported instead of Dayton, works very nice because
the tweeters are really the secret weapon.
Basically, PT2 SQ is marginally less than those $118 ribbons, 5-15% less on average, but PT2 is a more robust tweeter and can
take major torture without frying.
After months of my line array punishment, I finally blew PT2 fuses after cranking Slayer into major clipping.
I heard stories when people blew the precious 'fountek' ribbon on system turn on transients, you know
those little pops..
