new to forum but old to world (73 yrs). Moving to new house and have opportunity to upgrade my audio system. Since I have some hi-f hearing loss I want to emphasize good dialogue and start with a very good center channel and build a 5.1 or 5.2 around that cc. Currently have 5.1 Def Tech Procinema with Yamaha Aventage 660 receiver and it does ok in a much smaller space than new home. 80/20 on movies and soft rock music. New listening area approx. 12x12 but in an open area 20x20 with 10 ft ceilings and numerous architectural features. Will keep current AVR. With Hsu center speakers, I like the tech, neod magnets, etc. Question is - can I benefit from the horn tweeters or not (remember the hi-f hearing problems) ??? Horns vs coax ??? And yes, I know, the coax costs more so it must be better, if so, why ???
