I think both are very good speakers, so depende na lang sa taste, budget, and maybe aesthetics. I own the Titus FS in a similarly-sized room, and am very happy with it for both music and movies. To help you decide, I think you can audition the Titus Monumental sa shop ni sir Anthony; just message him through Facebook. The Monumental and Titus FS sound similar to me; mas may bass extension lang ng konti ang Monumental.
