If you also have a high ceiling, nothing will suit that size.
Try the clap test, if there's much of an echo you will struggle to get decent reproduction, whatever the equipment.
Ceilings are standard height (8' 0"ish). It is well carpeted and has a large(ish) 3 piece suite.
Never heard of the "clap test" but have tried it and there doesnt appear to be any echo.
