I have no problem with replacing the sub(s)...any suggestions? I'm no expert but what I cant work out is how just two ceiling atmos, the towers and centre will provide an immersive feel. Surely effective directional ceiling backs and surrounds can't detract from the experience? We curently have a blank canvas as the space is being completely renovated, decorators are not taking any preference. The living room is a about 40m² (5.5x7), with just a couple of pillars to the dining 17m² and kitchen 20m²...We are a good 3.5 m from the towers and maybe 3m to the centre speaker. Its a pretty minimal space, with a lot of hard surfaces, no carpets, drapes etc...so its bassy. I am up for anything and I know I won't get better advice than here, so everything is welcome.
