Speaker blending in symmetric stage setups

[physics]

The player's own instrument will seem very loud and clear at the focal point of the multiple sources, yet he can easily hear the rest of the band.

Great, thanks for clarifying! I own and have read both the mentioned books, but that point was still not clear to me as evidenced in my previous post. Now that it is, I'm further motivated to finish up the guitar wedge setup. Will report back after it's complete and been used for some gigs.

Thanks!

P.S. Tangentially, now that I've experienced the Triangle of Tone, and soon the Triangle of Power, I'm wondering how I can capture that experience in a recording so that listeners in headphones or with another stereo replay setup can enjoy it too. Time to learn about surround sound I suppose.
