I have not built it, but here is a link to a promising project. It is not super high efficient because the crossover point is used to compensate for the Eminence Alpha 15 in an open baffle, but it is probably about as efficient as you are going to get with a reasonable size. There is a more efficient design on that site with to 15" woofers and a Lowther (http://www.quarter-wave.com/Project10/Project10.html), but it is pretty big an a lot more expensive.

Do you guys suggest to build to pairs and stacked them -- one sit on top (upside down) of the other speaker like a d'appolito speaker array? Or just double everything based on the same drawings made it like stacking 2 speakers but in single cabinet
