Looking into the Tekton options, in your size room, I would recommend the Lore as your main speakers, and the m-lore as the surround. I have a very large room (35' x 15' x 8') and I am using the m-lore as surround speakers and they are excellent. Add a sub (Tekton offers some) and you would have a killer HT system that would sound excellent with 2 channel as well.
7.1 SETUP
LOOKING FOR THE "BEST" SPEAKER PACKAGE MAINLY FOR HT USE. WILL BE USING BIG BOX RECEIVER BUT LIKELY WILL ADD GOOD AMP IN TIME AND USE RECEIVER AS PROCESSOR ONLY. BUDGET FOR SPEAKERS IS APPROX $5000 PLUS SUB BUT THAT'S NOT SET IN STONE. LOOKING AT APERION, ASCEND, ETC. INTERESTED IN USER SUGGESTIONS. ROOM IS RECTANGLE 20L X 13W X 9H. WILL USE FOR 2 CHANNEL AS WELL BUT ONLY WITH SONOS SO SUPER REVEALING ISN'T HUGE ISSUE. LOOKED INTO SALK AS WELL BUT PRICING ON THE WEBSITE IS TOUGH TO FIGURE. THX IN ADVANCE.
