Can you? Yes. Should you? Probably not if you have other alternatives. Even with isolating devices between the sub and the electronics, you probably have other places to put them that would not be as directly influenced by vibration.
Can I put receiver and CD player on top of my sub?
Is it ok to put my receiver, cd player, and dvd player on top of my subwoofer? It is a big sub (15" getting 200 watts), the width and depth of the cabinet are long enough to provide a solid base for the electronics. I'm just worried whether vibrations from the sub will damage my electronics. Assuming CDs and DVDs don't skip, is this safe? I would really like to do this because it would be space efficient for my bedrooom.
