Key findings
- The receiver powers 9 channels; the front pair moves to the external amp so all 11 are driven.
- Estimated output at the seat meets a cinematic listening target with headroom to spare.
- Two subwoofers smooth bass across more than one seat.
Recommendations
- Consider a brighter projector if the room won't be fully dark.
- Place subwoofers at the front midpoints of opposite walls for smoother bass.
