I been using the 5" set for around 2 years now and they are still working great. Just bought this 3 piece set and set them up today..... I'm blown away. The hi's / mid's are clear as a bell and the bass from sub is slamming. Just dial in the filter on the back. Tested with Crystal Method, Strapping Young Lad, Oribital & my own music. The 5" set will stay too. The pictures only show one XLR / 1/4 combo jack input. There are 2 of those. See pic below.
For the price, I'm finding these to be worth it especially if you can get a used pair.
I'll probably pair them with an eq to get them a little closer to what I want but they do have bass and treble adjustments built in.
