These will move some air and require little to no eq

Magnetar,

I can't believe you're scaling back.  You were my hero with those
high performance OB's.
I'd scoop up all 4 in a heartbeat if it wouldn't cost a fortune to get
them down here.

Too bad E-V no longer makes their 30" woofers. WOOF WOOF!

[Russell Dawkins]

well Fostex apparently still makes a 31.5" one (for a price!)

... and this strange site has a link to an 18" wooden bass driver intended to be used without crossover to 3k where it is handed over to a tweeter! That would make an interesting OB.

I'm kinda changing directions - still open baffle but a line array instead of the WMTMW.

The array I'm building is a lot of work! I am using fifty drivers a channel. Between
cutting all the driver holes and wiring I'm hoping it is better then the WMTMW's... If
I stayed with the 21's  in the array it would be too wide to watch my TV... The arrays
with 50 drivers are the same footprint as the WMTMW's but more sensitive and have a
much wider range mid(s).

These are pretty darn sweet drivers. The way I had them mounted they didn't need any
eq on the bottom.
