Hello, Setting up my first ever HT and we have almost decided on 1 x 300 IW LCR 6 as the center channel and 2 x 300 IW 6 as the Left & Right channels. TV is at the center of a 12 feet wide wall. This entire wall has a hard plywood paneling. There is an air gap (cavity) of 4 inches between the front surface of this paneling and the front of the brick plastered wall behind it. So there is quite a huge volume of air involved here.\n\nThese LCR's are not fully sealed from behind and are partially open and will be inserted into this air gap. My concerns are:\n\n1) Can I simply install these as it is (open to air)?\n2) Will there be any push pull kind of effect when all the 3 are moving the same air in the cavity?\n3) Do I need to make a sealed and dampened enclosure behind each of these?\n4) Would this large air gap have any bad effect on the sound?\n\nThank you. God bless. Stay safe. Mike.
