I just couldn't confront the cost of buying Acoustic Panels so I made these at the weekend - I'm really pleased with them :-)\r\n\r\n[img]http://www.markholterman.pwp.blueyonder.co.uk/1208715062.jpg[/img]\r\n[img]http://www.markholterman.pwp.blueyonder.co.uk/1208715093.jpg[/img]\r\n[img]http://www.markholterman.pwp.blueyonder.co.uk/1208715128.jpg[/img]\r\n\r\nAs for construction; I'm not exactly sure what the stuffing is as I got it quite a long time ago from Wickes (I think), It's pink and claimed to have 'acoustic absorbency' properties at the time - also it is a bit more 'fluffy' than glass fibre and doesn't itch (which is nice).\r\n\r\nThe panels are made from pine frames (wood from B&Q) 70mmX20mm section, metal corner brackets - glued and screwed together. Used a router to chamfer all the edges and put a big rounded chamfer on the inside edge. The backs are made from perforated hardboard and they are spaced a small amount from the wall on felt pads. The covering is a heavy, unbleached cotton (I think) that I got from John Lewis' (no expense spared). The long thin one (behind the sofa) also has a centre brace but the other two didn't need it. They are positioned at the points of first reflection and behind the listener.\r\n\r\nI think I might well make another one for between the speakers so I might take some pics during construction this time if people are interested.\r\n\r\nThey have a really strange quality to them - if you hold one up to one side of your head you can kind of 'hear' that the sound is being absorbed on that side - very strange feeling - like holding a pillow or cushion up, but more so.
