I found the audiokarma econowave project, and located your site after reading.

It seems your designs are well tested and driver mated, which I value highly.

First, I bought the JBL horn lenses for the econowave project...can I use those?

Second, I can't afford JBL's right now, so, how big of an improvement is the Omega 15 over the Delta 12LF? It's double the volume, and double the price...double the performance? or not.

Plans would be great. Any help deciding?
