Have picked out the Ultimate which includes the ARC, Subwofer, and 2 ERA 300s. I have 3 questions:
- Do I Need, Should I get, 2 additional ERA 300s for the front of the room or will the ARC suffice? Is that overkill?
- Because of 11 or 12 foot ceiling should I get adjustable stands versus fixed for the two rear ERA 300s?
- I just purchased a Yamaha RX-A4A how will the Sonos system connect up to it?
