Thanks for the kind words. Open baffle speakers really need full range drivers with Qts. around .5 and higher. A project like this is very inexpensive and could sound really good with even cheaper drivers like the $13 GSR 8 from Parts Express:

GRS 8FR-8 Full-Range 8" Speaker Pioneer Type B20FU20-51FW 292-430

With these 8 inch drivers plus two Alpha's at $65 each and two 80 hz crossovers at $17 each one could build this OB system for around $200 plus a sheet of plywood or MDF. If you buy the wood from Home Depot they'll make the cuts for free and the driver holes can be done with a simple jig saw.
