I'm moving to new house and get to upgrade my home theater. I'm 73 and have some high frequency hearing loss (typically display the subtitles). We use our HT for 80% movies and 20% soft rock music. I want to start the new system with a very good center channel speaker for dialogue and then build a 5.2 system around that center channel. Listening area will be about 12 x 12 but open to around 20 x 20, hard floors. Existing 5.1 is Def Tech in smaller listening area and it does a fair job, I'm looking for upgrade plus handle the added volume space. Any recommendations on cc to start with ?
