Well this is a late response, but I too have a large room with 16' vaulted ceiling. I am going to purchase the compact over the LFM-1, so I will let you know how it works.

P.S. per Gonk he recommends the LFM-1 for our room size, but I suspect the compact will work fine for your music, and mine is mainly for movies since I have towers.
