I've just purchased a set of Q Acoustics 2000I series 5.1 speakers. This is for a cellar and therefore I'm not sure I can install wall brackets due to damp proof lining. I've been looking into speaker stands however I'm thinking of using an old oak beam I have to create two tall stands and one mini stand for the front speakers. Acoustically are there any reasons why this wouldn't be a good idea? They would be heavy & solid. Would I be best to put rubber bases (halved tennis balls), metal spiked feet, or leave flat on carpet? For info: my cellar has an arched roof and is approx 4m by 4m in size. Has anyone else had experience with cellars and installing fixtures on the wall.
