Hi, I'm slowly building a system (of sorts) but money is extremely tight presently. I currently have: Onkyo CR515 running through a pair of Aego-T speakers Old LG3350 DVD player (ultimately to be swapped for an HDMI based model) Sky HD Box Samsung LE37R87BDX LCD I'm looking at getting either an Onkyo TX SR505E or SR605E in the near future to hook that all into and allow me to get surround sound set up. (I've been donated a pair of old Wharfedale Diamond speakers - can't see a number reference on them, sorry - that I intend to use for surrounds). I have enclosed a diagram of the room layout with red 'S's for where I propose to put the Wharfedales - due to space constraints one will have to go on a windowsill and the other on a shelf in a dvd rack. The room is 11 feet (window side) by 14 and a half feet (wall with TV on). The exisitng speakers are placed as close as I can get to be equidistant either side of the TV and around head height of someone sitting on the sofa (it's actually an L shaped one but Visio doesn't have one of those in it's toolbox). I'd be very grateful if someone would take a look and offer some suggestions: 1. Is it worth adding the surround speakers in the current locations? (if not - where else would you suggest - if wall mounting is better I do have wall mounts for the Aego-T's but would prefer to keep those as the fronts as I suspect they'll be better than the Wharfedales) 2. Is it likley to cause any major issues combining the two sets of speakers? (Bearing in mind that I will probably add a centre speaker from Wharfedale at some point too to sit below the TV - really no room or money for a sub!) 3. Will a centre speaker be worth buying - will it improve things noticeably? The Onkyo amps seem well received so unless anyone has other suggestions for that area I'll leave it there - many thanks if you've stayed with it this long! Cheers, Jason.
