Hello friends My current set up AVR - Yamaha A870 LR - B&W 603s C- B&W HTM 6 Surrounds- BOSE 301 Series V ( yep Bose - currently sounds good but hopefully moving to B&W 607 ) Sub - No Sub and will not be having one due to some restrictions I have ONLY one POLK Center CS 10 and was wondering whether a.I can connect the Single Polk Center to One of the Atmos Terminals ( Front presence High). The other remains unconnected b. Place them on the ground or on a pedestal Facing upward ( dont laugh now :) . It looks amazingly silly for the polk to sit there and Look Up) c. Turn the Atmos Level to Max I wanted to check whether it would impact either my avr or any of the other speakers. Thank you in advance. Rajesh
