Will this cause a problem? I am ripping up my lounge right now to install my new kit properly (may put pics up sooon actually - its been a bit of a mission and one that forum members may benefit from). I have channels chased into the walls to house the cable for my new Orb satellites (which sound great BTW). Problem is, a radiator is being moved from under the window to a vertical type up the wall - great - creates more space and will look very cool ... but... it will bring it pretty close to the proposed site of one of the rears, which are metal cased, and I was wondering whether exposure to heat is a major no no. Dependant on the radiator placement the speaker could be as close as 6 inches from the edge of the radiator. Feedback much appreciated.
