Sounds like you will build a very fine home theater. The four π loudspeaker is perfectly suited to your purpose.
Many people build the center channel sealed. It allows the waveguide to be centered in the center speaker. Keep the right and left channels as shown in the plans, with the left speaker having the tweeter on the left, and the right on the right. This is a great setup, acoustically and aesthetically.
I've send plans via email. I suggest reading the material in the π Speakers FAQ. A general overview can be found in the document called "High-Fidelity Uniform-Directivity Loudspeakers." There is also plenty of other good information and construction tips contained in the FAQ.
