That's what I love about eD, they're still a small enough outfit to cater to the individual. Check out their forums, they've got a dual 18" sub coming out very soon. The A7-900 I believe it's called. Somewhere in the neighborhood of 1000w RMS.
Here's a thread showcasing the size of the smaller A7-700 sub.http://www.icixsound.com/vb/showthread.php?t=31045
All I can say is, to hell with WAF! With subs like this, you can order a second empty enclosure and stick the ol' lady inside!
