Used them a lot. Sounds decent with some eq, you'll need two subs to keep up with one top.
Subs are very hot around 80, nothing below 50 hz.
Pretty good "throw" outside compared to similar sized tops.
Inputs and powercon are top/bottom, not good.
Used to have three subs on a dolly and two tops in a flight case for each side of the stage, roll in the subs, put on brakes and lift the tops on top.
Stock wheels from EV are bad, after a few years you'll have to replace them.
Don't stack anything on the subs grills. They bend easily.
On the plus side, I don't think we replaced a single driver or amp module in 5 years, even after some surprise showers during the summer.
