Hi guys, Im planning on a 5.1 setup initially and possibly expanding to 5.1.2 in the near future. I have been all over the place from SVS prime 5.1, Klipsch reference theater pack (I know, small entry level sub-optimal speakers), but to avoid needing to upgrade in some years, I was looking into Klipsch Reference Premiere line for my small/medium master bedroom (see picture) (5 m x 3.1m x H 3m aprox.). two options stand between RP-6000f/RP 8000f Tower speakers,, and RP-600M speakers, as my FR and FR, both with a RP-504C/404C center channel (primary interest is movies). Taking into account room size, will the tower speakers be overkill, or do they offer enough mid-bass to justify going over the 600M bookshelves. Also, can I go with 4 bookshelf and a center channel for a 5.1 or should rear speakers be smaller. Both these options will pair with a Sub (possible Rel HT/1205 sub or klipsch SPL-100). Thanks in advance. Im open to alternatives best suited for room size, and top-of-the-line sound quality.
