i have a customer that bought an Arc Sound bar. They are replacing their previous sonos sound bar. It is set into a solid wood beam. 6” x 12” x 72” wide with a 48” wide cutout in it. I believe the new arc is 45” long. This would leave 1-1/2” on either side of the arc for space. Will the sound work properly coming out the side and bouncing off of the wood that close. if i made the space wider would that be adequate? other considerations were to bore a hole the size of the speaker through the end of the beam so the sound could travel though (12’) the sides. or one other would be to disconnect the speaker at the end of the arc and mount it to the end of the beam. There is a finished speaker cloth grill in front of this when done.
