Hello all - I have a room with a 60” TV above a fireplace mantel. From TV to back wall is 27’. From center viewing position, right wall (windows) is 6’ to right. There really is not left wall up to 7’ as it is an open concept that spills into a kitchen and hallway. From 7’ to 15’ the left wall is 6’ to left. The ceiling runs at a pitch from 7’ at the right to 15’ feet on the left - again from the viewing position. Basically, it is a long room with a high pitched ceiling. Adding a beam on the mantel (approximately 6’ from floor) made a big difference as compared to the TV speakers. Adding two Ones along back wall and a Sub(3) was nice but really not as big an impact as I was hoping. Downstairs, I have an 80” TV. From TV to back wall is 12’ and from side wall to side wall is about 27’. TV is situated on the right 13.5’ of the room. Drop ceiling height is 12.5’. I just installed an Arc with a Sub (3) and so far so good. Should I relocate the larger Arc to the larger room and the smaller Beam to the smaller room? I am thinking I should keep the Arc downstairs where it will perform better and keep the Beam upstairs and live with it until I purchase something more suitable for that size room, which may be neither a Beam nor an Arc nor any soundbar. The sound is good upstairs just not great or particularly impressive. Thanks everyone!
