I am looking to improve my current set up, illustrated in the photo attached.\nI have Onkyo TX -NR609 amp. B&W HTM 7 central speaker. B&W ASW700 sub, Klipsch R-100SW, couple of B&W 703, couple of B&W FPM 4 at the back behind the sofa. The ASW 700 is awaiting repair , hence the Klipsch, and one of the 703's is awaiting a new tweeter......so no hurry. I have had the B&W 's from new, about twenty years, the ONKYO is about six years old\nTo improve the set up a local audio company has suggested replacing the Onkyo with an Atmos Amp , adding a couple of height speakers in the ceiling above the seating area, moving the central speaker up (will have to be replaced as its too big for the recess at the top) adding some acoustic material to all recesses holding speakers, and adding another rug.....as the room is very hard.\nAside from the addition of the acoustic material and the rug, I want to make no aesthetic changes or move the 703's.\nI have an estimate from them to add B&W central and height signature speakers and an integra amp. With installation $6000+. Needless to say I won't be going for that option, however good it may be. We only watch TV on this set up, mainly through apple tv and digital satellite.\nI guess my questions are.\n\nDo I need to move that central speaker higher\nWill the height speakers make a worthwhile difference\nIs there any need to pay big money for the b&w and integra stuff for this type of use\/set up\n\nAny suggestions\/advice would be appreciated.
