I am looking to up grade my HT system which currently utilizes a Yamaha RX V592. I am thinking of going to the Yamaha RX-V1400 and also updating my DVD from a Toshiba SD-1600 to a Denon DVD 1600. My question concerns my speaker set up. Currently my fron speakers are Klipsch 1W-150 in-wall speakers for my front speakers and and Klipsch KSB1.1s for my rear speakers. If I go to the Yamaha RX-V1400 I will need to add two new surround speakers. Due to the set up of the room where I have my HT, I need to figure where to place these two new speakers. Has anyone put the surround speakers in the ceiling? Is this an option? Any suggestions as to what speakers to consider if this is an option? Thanks!
