Oldears, I had no real choice in our 1500 ft2 place in New Mexico mountains. It is 10 x 13 x 8 and must also on occasion serve as a bedroom. Fortunately, I discovered the Zilplex cups. I still remember listening to Diana Krall's 'A Case of You' without them. It was okay but obvious that I was in a small room. Then I put the eleven Zilplexes up where the instruction said. When I resumed playing, I was shocked to hear myself at her concert! I had the eerie sense that were I to stand and walk forward five feet I would fall out of my listening room.
This is not to say, of course, that the irregularity of many rooms means they can be made easy to work room with the Zilplexes, but neither will spending more money on your system.
