Mackie srm-450 constant annoying hum (buzzing) even with no input plugged in
I've tried ground lifting, but it did'nt help. Is this normal for these speakers? All of mine do it. I used to have a very quiet, clean key rig. Is this why they came out with V2? Are they quiet? Is there a mod that can be done to these to resolve this? Thanks in advance for any help!

Mix, try this...Get everything in your audio system together.get a coupla power strips. Power up both speakers on that strip with no inputs, just the speakers. gotta hum(60hz)? ground-lift the strip and see if it stops. add one peice of the puzzle at a time until you find your buzz generator, if you're a mobile DJ, doing gigs in 'God Knows Where' you would be well advised to buy a "Power Conditioner" that will level out spikes and dips in the voltage servicing your gear.
