OK poultrygeist. It has been ages since I last posted. I kinda fell off the map after asking you for a considerable amount of help with my build based on your recommendations.
Anyway many moons ago I ordered the Eminence Betas and Alphas. then I got a way behind in my remodeling business and they just sat. Well any way I do not have a to do list, I have a get done list of projects started and never completed. I finally got this one done.
I took a slightly different route. I went to a concrete supply house and bought an 18" inch round concrete form tube. It is made of heavy cardboard. I made a plywood insert that I pushed in the middle of the tube then mounted my Alpha 15-A in that. I then cut a circle in a large plywood panel and pushed the whole thing into the panel. I then glued and screwed each to the other to make a somewhat uniform unit. I then mounted my Betas and tweet into the larger board.
I wired the Betas and Alphas in parallel to give me 4 ohm and hooked them to my class-d audio amp. I then bought a small Topping 30 wpc amp to drive the tweets.
Long story short. They sound awesome. Way beyond my expectation. You had told me they would replace my Maggies. There is no comparison. They are much better in clarity, dispersion, and expansiveness. I love to be enveloped in the sound. Further they are very clear and enjoyable at low volumes.
I love to have a glass of wine and close my eyes. I swear I can reach out and touch the instruments. Because they are so much clearer and defined it is easy to become even more critical. I also long for some Tangs but I am not sure I can justify the extra cost.

Anyway, thank you so very much.
I am lovin it!
