I'm using it at home in the basement with an Alesis DM10 Pro kit. It is also powering a Box PA M 12 Eco on the other side of the kit. I wanted it specifically because the DM10 is a pain to set up to output in mono, so two inputs were preferable, although, of course the line and mic inputs have different impedances. Will probably use this set up as stage monitors for the occasional gig that I do. They will be better suited to this than as monitors for the drum kit as it is not a fan of some of the more aggressive bass drum hits. Live the drum monitor will be a mono feed from the desk to a more powerful amp.
Pros: does what it says on the tin, decent quality of sound, effective tone controls, automatic standby available (kicks in after about an hour). Seems well enough built, it's quite heavy but easy enough to carry with the handle and using the top hat mount as another hand hold, so I don't see this as a negative thing. Has a top hat mount so you can use it as a PA speaker too.
Cons: not very loud as a drum monitor, it clips quite early on kick drum hits. Much better as a general full range system. The standby system is weird. It is automatic, operating after about an hour after the last input signal, so you get the impression that pressing the standby button does nothing. Why it could not be a simple standby switch is a little puzzling.
In conclusion it really is quite a bargain. Would be ideal with an extension speaker for a small venue monitor system, it's OK with my Alesis kit for practicing and I am please I bought it as it is versatile enough to be used as the basis of a small party PA system, stage or drum rehearsal monitor. Recommended.
