Fits great on the ZLX, and also is a near perfect fit for the Yamaha DXR12, except of course there is only one side handle cutout to use to carry the DXR12.

Although it's not quite as perfect (the top handle on the QSC is a bit more recessed), they're still a great fit.

Excellent quality and good fit

Easy to put the cover on the speakers and perfect fit.
