J have read and heard from people throwing around with the facts about EAW cabinets and drivers inside them. Personally j have seen (a peak only) a LA 400 sub bass cabinets and that’s it. Other side of the coin is that so far j have never seen or heard that someone have successfully cloned any of the EAW enclosures especially mid high and high. The company is more than conservative about giving away the facts about drivers used. Me j am just another mortal with a very tight budget dreaming that some day ill have the real product not the copy. In the mean time j am more than interested in EAW bass cabinets, j have collected almost everything j have a chance to put my hands on from the various sites and persons. If anyone have built something from EAW j am interested in building plans and techniques used. 
hi
ok here goes
eaw is tied up with rcf & uses rcf drivers
rcf is owned ( whole or part - i dont know ) by mackie
mackie uses rcf drivers in europe
eaw uses rcf drivers in usa
both uses standard rcf drivers and made to order rcf drivers in their various designs
i have found that the drivers chosen - designed or speacially ordered for a certain cabinet
are very very well matched - giving the best possible application of that driver to a cab design

The exact same question was asked on the EAW forum just a little while ago, and the person's head was promptly bit off by one of the forum regulars. An EAW representative then stopped by to say that EAW uses parts from over 20 different manufacturers, and that RCF drivers make up only 20 percent of their total production.
I have seen a picture of the older driver used in the LA400, the one that handles 500 watts, and it isn't al that crazy to look at. In terms of robustness, it's got a stamped steel frame and an accordion surround. The Eminence HL10 and Eminence Lab12 look much more robust. I'm currently working on a horn for the Eminence HL10, but horn design is really, really hard. Making matters worse is that, ironically, the HL-10 doesn't seem to really like to be horn loaded. It seems to like vented boxes a lot better, and so my work with the HL10 has been characterized by lots of trial and error.
