I have a pair of Alesis Mk2 Active monitor speakers, currently positioned on a window sill wired into each other and into the matster out of the Mixer. I've never had monitor speakers before and just want to know if I have them setup properly?? and whether having them on a window sil with glass behind them is gonna make a difference to the sound. Is there any Do's & Don'ts for speaker setup?? help a bruva out here.
