The Good:
* Lets you repurpose a speaker cabinet into standalone vocal PA for gallery-sized spaces.
* Makes for a clever vocal practice setup -- two mics, line-in for your backing track, speaker out so you can hear it all, and line-out for your recorder.
* It's a very quiet amplifier (as inexpensive PA's go), and sounds at least as good as the speaker I mounted it inside (a Bag End S15X).
* It's handy being able to drive a second external speaker.

Things to be aware of:
* No phantom power for your condenser mics
* It adds 15 lbs to your speaker weight!
* You'll need 3 1/2" depth clearance inside your cabinet
* You'll want to color or change the main volume knob, so you don't confuse it with the others.

I've installed this amp into a Fender speaker cabinet with an 8 ohm impedance and it works quite well. Adding another 8 ohm speaker as a slave works for awhile and then the unit goes into protect mode.
The only way you know this is if the unit just stops working. As mentioned by others, there is no indicator to tell the operator the unit has shut down.
Turning it off and then back on re sets until the next event.
It seems the unit is not suitable for two 8 ohm speakers even though the instructions say it will work.

It looks like the factory is now trying it's best to decrease the amount of air leaks in the amp. They must actually read the reviews...

All and all, a good value.
Installation is easy even for a non wood working talent like myself.

purchased for monitors. our wedges are 2-way, 15", ported.

Amp quality seems very good. knobs are tight but smooth, and shaped to prevent crushing the electronics if bumped. larger components are glued to the boards to combat vibration. aluminum plate is nearly 1/4" thick, very solid.

Installation is easy, but mounting flush requires some woodwork. Wish the plate was flanged for easy flushmount, which you really need with this kind of gear. I used angle-iron to make a shield, since my cab was too small for a woodworking-flush-mount-special.

Sound quality is very good into a ~6 ohm speaker. clear highs, good lows. doesn't get that warm.

NEEDS A LAMP TO ALERT OF PROTECT MODE. Ours quits immediately when adding a slave speaker. I can only assume it doesn't like a 3 ohm load. sorta picky for a 4 ohm rated amp. Hard to troubleshoot when it goes into protect mode.

I'll pay $120 for a few more, but not the listed $150.
