My parents retirement home burnt to the ground following a lightning strike (what an ordeal) and they are now in the late stages of rebuilding. My mother loves music and wants my help in designing a new complete system for her home. To that end, I need some help on speakers. Here are some of the constraints for selection: 1. The room the system will be in is huge with 20' ceilings. 2. She is not an audiophile, but loves fullness of sound. I don't believe she could distinguish the difference between a Polk and a Diva/Paradigm. 3. Her budget for speakers alone is around $1,000. 4. She will use the system for a combination of music and home theater. A little more music than theater. What speaker system would the experts here suggest for such a limited budget and such a large room?
