Re: 3.1 Suggestions for this room
Could go with 3 HTM-200's across the front. They are sealed so putting them inside the cabinet should not be an issue. They are also a small enough to fit underneath your TV. When used as a center there only 6.5 inches tall. Where would you be putting your sub? Could you put it next to or behind your couch? That would allow you to run the sub at an lower volume putting less strain on it.
