hi all, please don't bash me... I know I should know all this.. I also know that there have been some threads about such questions in the past, but just help me out here I've moved to a new house, where I've got finally my own practice/music room: 4,30m long x 3,25m wide x 2,42 m high. I've got lightly furnished walls, some shelves writing desk and the usual stuff in there, but no special acoustic dampening measures. What would be the standing wave frequency in there and how far should I place the cab from the wall to avoid booming. I've got a decent hifi in there to act as band substitute. Any tips on what to put on the walls ? The floor is carpeted btw., walls are hollow core bricks with gypsum board cladding, which is prone to vibration. Any recommendations ? Thanks guys.
