Glenn, I just screwed a fold down leather luggage handle to the top of the woofer. I figured out where the center of gravity was and placed the handle over that spot. The woofer hangs down nice and straight and is a breeze to carry.
I plan to permanently mount the Z2200 control unit to the woofer ( I find no need to adjust anything while performing).
Also will replace the Satelite cables with heavier wire and phone plug ends, plus changing the jacks on the woofer to 1/4 inch phone plug types instead of the RCA jacks. These have not given me any trouble so far but have to be handled with more care than if they were phone plugs.
I will also change the plugs on the audio input cable to phone plugs so they will plug into the keyboard directly without using an adapter.
