A crossover might be used between center driver and surrounding ring to make a sort of virtual concentric/coaxial driver.

Wavelengths at bass frequencies are measured in feet. Two bass drivers in a speaker act like a single point source. Tweeter frequency wavelengths are measured in millimeters. Hard to get most...

Divide what then, exactly?

"Cost you've invested" is the price, unless you are the manufacturer. Cost is the manufacturers side. Price is the consumers side. What you invest is the price. ...

Your post confuses cost and price. You talk about stripping out cost of this, cost of that. But then when you divide by 2 or 7 or 9 you are talking about dividing price by that much. You have no...

Why do people continue to believe that products in a niche market have prices that are directly related to cost?

The "analysis" in the OP is irrelevant.

4 ft separation on the back wall is fine if you are doing 7+ channels and will have side surround speakers on side walls too.

Do you think the performer wants you to hear his performance or the creation of the recording engineer? I think a valid question at least.

Yeah, and listeners determined that Edison's phonograph sounded as good as the real thing. Sometimes what we "determine" is limited by what is available and practical. Things progress. Just sayin.
