Hi, I would like some advice about my home cinema setup. The room this is all going in is 4.7m deep by 5.3m wide by 2.2m high (25 sqm). Viewing distance is about 3.2m from the screen. I am planning to wall mount the TV, as well as wall mount left, right and centre speakers around the TV and mount the rear speakers in the rear ceiling corners. My current kit is as follows: Source HTPC (Asus Xonar HDAV 1.3 Slim soundcard and other high quality parts) TV Sony Bravia KDL 40W3000 Amp Onkyo TX-SR605 A/V receiver Speakers Monitor Audio Radius R270 standmount left and right speakers Monitor Audio Radius R270 standmount left and right speakers Monitor Audio Radius R225 centre speaker Monitor Audio Radius R45 rear speakers (just two) Monitor Audio Reference Silver Sub RSW12 Cables Subwoofer wired with QED MP-SW 10m lead Front, left and centre wired with QED-Silver XT Silver Anniversary cables Rears wired with QED original cable A massive list of questions I am going to be upgrading the TV soon, to something larger than 50". I'd like something reasonably future proof so 4K I guess, but I am not that interested in 3D. Any recommendations? I am not too concerned with upgrading the HTPC as I did that reasonably recently. It is a nice large HTPC box with good components and runs reasonably quietly and cooly, Windows 7 with a customised Media Browser setup. Nice soundcard and BlackGoldTV card. I am also planning to wall mount the amp and HTPC, so that only the fascias protrude into the room, through a dressed aperture in a stud wall. The units will be supported on shelving and the rear end of them will be in a large understairs cupboard to keep all of the cabling out of sight. Any issues with overheating? The front 100mm of the units will be sleeved in wood probably and I know the Onkyo runs hot, but surely it can keep itself nicely cool thanks to the rest of the air inlets being in a reasonably drafty cupboard (actually about 1 meter deep by 3 long. I have attached some sketch ups of this idea. It will cost me less than getting a ridiculously expensive AV media bench with vnetilation I figure. Once in the cupboard the units can make as much noise as they like and the wiring is not so much of a mess either. The cupboard will also house routers and switches and a NAS. My rear Monitor Audio R45 speakers always seemed a little anaemic to me. Okay I noticed them from time to time during better audio engineered movie scenes and they worked ok with all channel stereo, but I am guessing that the room I just moved this equipment into is a little large at 25 meters squared for them. I would prefer to wall mount the left and right channel speakers but right now I have floor standers. They always seemded okay to me, but again, are they a little smaller for a pretty big living room? If I wallmount speakers woudl it be a good idea to stick to the Monitor Audio Radius range? the 225 will go on the wall nicely already as the centre, but what stereo fronts to match it with? Should I be looking to match the Silver RSW12 Sub? I have to rerun cables through the ceiling and will probably have lengths left over from my last build that are too short. If I get new cables I am tempted to get something cheaper than the QED Silver Anniversary XT, something like the QED original cable. I just don't think that more expensive speaker cabling is really worth it. However the speaker cablng will be near LED spotlight cabling in the ceiling so maybe getting cabling with better shielding is worth it. I am planning to use babana plug face plates for the rear speakers to make things neater. Maybe that changes something? The Subwoofer I have was the most expensive bit of the kit back when I bought this setup circa 2009, so I probably don't need to upgrade there. It was always turned down a fair bit so as not to overly shake the floor (which it definitely can). I live in London and have neighbours everywhere and don't really need them complaining What to use on a wooden laminate floor for the feet though? Spikes or rubber feet of some kind? So which bits would you change in this kit? What about mounting the amp and HTPC in the wall like that? Anyone have experience of trying something similar? Are wall mounted speakers just for Bang and Olufsen types? Massive thanks for anyone willing to offer some advice.
