These are great, I've been using them for years.
They are more than loud enough to hear over a rock band,
They stack nicely in the car
They can be positioned horizontally, vertically, or on their ends, as the situation requires.
There is no signal lost on pass-through.
Most importantly, the cable access and controls are hidden from the feet of the audience, unlike many monitors. This is really important in pubs.
They are a bit awkward to carry, that's the only downside.
