What I like: very lightweight and sturdy, good control of the sound through onboard tone controls, combo jacks. I bought two along with a Mackie mixer for a low-volume Americana combo. That was years ago and I still use them. BUT....
What I don't like at all: The speaker distorts when set at more than half its volume range -- an ugly distortion. In its useable range it's still loud enough for an outdoors show for 50 people, with a trio of electric guitar and mic'd percussion plus vocals, but you are quite limited instead of liberated by the gear. I hoped the problem would go away when the speakers broke in, and I was wrong. If I had it to do over, I would buy better branded speakers, despite the fact that the better ones weigh more.
Update: after years of trying to work with these speakers, I opened one up yesterday to chase down the rattle. I found several loose screws (poor quality control), tightened them and removed a couple that bizarrely served no function. Ran the speaker with the cab open, and realized the problem came from the woofer. It's really garbage -- small magnet, WAY too small for the power rating. It could not handle the line out signals from my amps without distorting in an ugly way. I put in a quality 8OHM woofer I had lying around, and it transformed the device: more power, clarity and tone. I'll replace the woofer on the other one too. If you go this path, be careful to install a woofer with a relatively low profile, because there's not much room in there. I reaffirm: The better path would be to buy a brand that doesn't require surgery in the first place. The replacement was not complicated, but it was certainly tedious.
