Richard,My house is a 34 foot diameter 3/4 sphere geodesic. The widest part of the house is 6 foot above the main floor level. Each facet is a triangle roughly 7 foot on a side. The first side reflections, which are minimal because of the distance, get reflected up and not toward you. The maximum ceiling height is a bit over 21 feet. I run mine with the listening position about in the middle. The dome section is basically one great room. The only enclosed area is the bathroom.
I've been in bigger domes where the speakers were placed about 4 foot from the wall with the listening position about in the center. This is pretty close to what you get from a bandshell.
There are hot spots where the volume is higher than in other areas, especially if you are near the back wall and in the spot where several of the facets are focused. Similar to the sidewise first reflection points, any backwall echo is directed up and not back at you. Sound hitting the next tier of facets is directed down so it hits the floor behind you instead of coming to you.
In the northwest the Tacoma Dome is one of the better places to hear music. We stopped going to Seatle for live amplified shows unless the show is in the Tacoma Dome. You get reasonably good sound at most all of the seats. You have to be in the last few rows to get any kind of backslap at all.Please don't confuse the sound you are getting from a concrete structure with the sound you are getting from things being round. The Tacoma Dome is a plywood dome and sounds good. The King Dome was concrete and was possibly the worst sound on the planet. Someone here posted about using echoses in a storage tank as part of the composition. Casals used to practice in an old cistern because he liked the sound. His cistern was rock and so the inner walls diffused reflection instead of focusing them like a true circle would.
If the wall behind you is dead, or far away and multi-faceted, or non-existent (like a band shell) then a partial sphere can sound just fine.
