Here is my current HT configuration. 55 inch Panasonic plasma and three B&W CCM 818 in-ceiling speakers for LCR and B&W CCM 684 in-ceiling for the surrounds.
My wife loves the in-ceiling as no speakers are showing. However, the sound image is less than optimal. For HT it is not too bad, but for two channel listening you really have to be on the ground to enjoy the music.
My plan now would be to place the B&W 805D on stands and place the HTM4 on the AV cabinet below the TV. If placing the HTM4 on the AV cabinet significantly diminishes the sound quality, I could just place on a stand and move the AV cabinet elsewhere in the room.
I will need to move the two chairs that are currently to the left and right of the TV as they would impede the new bookshelf speakers.
A couple of questions:
1. Should I keep the L and R in-ceiling speakers that are adjacent to the TV as front heights or wides. Alternatively, I could use the speakers in my kitchen in a separate zone.
2. Should I move the C in-ceiling speaker that is above the TV and move to be a surround back speaker. I was only thinking of having one surround back speaker due to the small size of the room.
3. I currently have an Onkyo TX SR 805 AV receiver. It has 140 watts per channel and Audyssey MultiEQ XT room correction. Based on my room configuration would I significantly benefit from Audyssey XT-32 or additional features on a more current AV receiver or PrePro.
I welcome any other suggestions you may have on my set-up.
