I've tried a few of these portable AC-powered portable PA/monitor/music speakers with built-in amplifiers and near as I can tell, this is the best one in it's price-range/class.QUALITY: Right out of the box it looks nice. There's something about the fit & finish, and the layout of the controls, the design of the enclosure, even the packaging that communicates good quality. Everything is crisp. The lettering, the definition of the angles of the enclosure, everything is nice and clean and feels high quality. LOOKS: The front of the speaker has a very nice, back-illuminated logo.ENCLOSURE: The speaker has a handle built-into the design of the enclosure on the top to carry the speaker by, but the speaker vents on the sides (or top & bottom if using the speaker horizontally) are also handles. Horizontally is how I will primarily be orienting the speaker, and when set on a flat surface the speaker's face is angled up slightly, the same angle as a floor monitor. Perfect. The control panel, which is on the rear of the speaker, is well laid out. The speaker is fairly heavy. I attribute this to good quality internals, big magnets on the speakers, lots of heavy capacitors, etc., rather than the manufacturer just adding weight-plates to make it feel heavy & substantial.SOUND & POWER: The sound is average, typical for speakers of this type. It includes bass & treble controls, along with the standard volume and pre-amp gain controls, and they work quite well. The manufacturer advertises 100 watts RMS. I think that figure is optimistic. During testing the most I could get it to pull at peak was about 70 watts. That translates to somewhere near 35 watts of output. There is an LED indicator on the control panel on the rear which illuminates if the amplifier detects clipping (distortion caused by overloading the amplifier components). It never lit while I was using it. My power figure estimate is based on this being a class AB amp (why they didn't go with a class D I can only guess) and average Class AB amp efficiency is ~ 50%. The manufacturer claims 102db @ 1watt/1meter. That is a pretty efficient rating (it's a rating of the speaker, not the amplifier). I was able to get the speaker to put abut 110db @ 1w/1m. Maybe it could do more with the right audio sourceCONCLUSION: This speaker is much better, I figure twice as good, as the similar speaker from it's nearest rival, a firm whose name rhymes with mile. For the money it seems like quite a piece of hardware. When you consider the cost of portable Bluetooth speakers (this speaker supports Bluetooth, SD card, RCA line in, 3.5mm line in, USB, XLR, & 1/4" inputs. It even has an FM radio.), this is a lot of speaker with a lot of capabilities. Considering it has a 10" woofer with separate tweeter and the various functions (albeit without battery power), this is quite a lot of hardware for the money. This speaker comes with a remote control and supports XLR line-level output.Good looks, good quality, good performance, good sound, good feature set, and easy to use, this speaker is a smart choice.
