[26 x 22 x 15"] I used this, as well as the Samson Concert 288 wireless microphone system, for an all day event with about 100 people under a large tent. I was able to connect a PC audio (with video going to a large flat screen TV), two wireless mics, an XLR input from a solo musician's system and Bluetooth connected to my cellphone to play music. I could easily switch between inputs and adjust tone. The sound output was good, with the sturdy speaker stands elevating the speakers above all heads. The system is very portable, with the amp/mixer snapping into the side of one speaker and a small storage space in the other speaker for power and speaker cables. The two speakers slide together for easy transport, except the comprehensive instructions did not tell me how to get them apart. They are shipped with thin cardboard between them so you have to keep hitting them to slide them apart. After the first time they are separated and the cardboard removed, they slide together easier.
My only concern is that the amp/mixer locks into the side of one of the speakers, leaving all of the face exposed. It would be better if there were some sort of panel to cover and protect all of those controls and inputs.

[15V] I purchased this system to use when doing vocal shows at small halls. I tested it out at my place and found it to be very easy to use, powerful enough with some interesting features to enhance the sound. Not very light at 50 pounds or so, but it packs easily and should transport with a hand truck without difficulty.

[15V] I have no sound board skills and I figured out everything. Great sound and so simple.

[15V] Gigs have never been so easy. Set up and tear down is a snap. Sound is better than expected.

[46 lb] Works great so far, easy set up.

[15V] We got this system to replace a Fender portable 150 Watt PA. The new Fenders lack controls. This thing has more inputs, much better controls and the sound is outstanding. The people watching on our internet broadcast noted immediately that the sound was much crisper and clear. The speakers are heavy but really good sound.

[15V] This system is compact but it packs a lot of power. It has incredible sound and the controls are easy to use and master. I was especially impressed with its Bluetooth capability. I’m able to connect my PC laptop or iPhone which gives me the ability to play any accompaniment music that I want

[15V] A great all in one PA system. Provides ample sound amplification to fill a large gymnasium sized location with ease. Lightweight for easy transport of both speakers and the mixer by one person, in one trip. A great variety of different types of input sources and easy, full control over each source in the mix.

The only "negative," which isn't even really a negative, is the cooling fan in the mixer/power source that runs while in operation. It could be considered a negative in that you can hear it operating if the room is quiet while you're not playing anything, so you'll want to keep it away from any potential microphones that may be recording the sound of the audience, for example. But it's a positive in that the unit won't overheat when operated for hours at a time. So not really a negative.

Highest recommendation for an easy to transport, powerful PA solution!

[15V] I use this is a school setting - cafeteria, professional development sessions, etc. The handheld wireless mic is awesome - clear, great sound, volume level never an issue. The Bluetooth has come in handy on many occasions for connecting laptops and smartphones. I bought stands to go along with this set - totally worth it and truly completes the set. I am fully satisfied and would buy this again.

[46 lb] I generally play with one other person through this, but occasionally we get guests who either sing or need to plug an instrument in. This can accommodate all of us and we use the BT400 not the 600. We use a Mackie thump speaker out of the subwoofer port which helps with fullness of the sound, not that it's bad to begin with. The only amp we used to bring along with our old PA was the bass amp but don't even need that anymore. Awesome sounding, portable and all the basic functionality you would need for a two or three person crew. The portability is awesome, we only use when when we play out as we have a dinosaur Peavy PA for practice that stays where it is. I use this Yamaha as speakers for my computer if I know we have a lot of time between gigs. Awesome for just playing music or trying karaoke at home too. If you're going to be playing a passive instrument through channels 5-8, you're going to want a booster.
