As binners says, get a proper 5.1 surround set-up, the sub can be hidden away behind the telly, or the sofa, which is where mine is, and the little satellite speakers go up on the wall, where they are hardly noticeable. If you can spend a bit, then KEF or B&W do some beauties. If you’re replacing a quality pair of big boxes, then good quality speakers will give you good music repro as well, which is how my system is set up. If you’re not bothered about 5.1, then 3.1 would probably do, but a good surround really can make a difference when watching TV; you’d be surprised how often proper surround adds atmosphere to TV programmes, not just to movies, people talking behind you, doors slamming, cars and other vehicles moving behind, etc.
