Reviews

Extremely happy with them
I use this a as field monitor for my high school marching band and for a crazy loud bluetooth speaker in class. The sound is great, considerably better than I expected for the cost. Bluetooth has worked great for marching rehearsals and using a metronome in class. Not sure what the battery life is like. I've used it all the way through a hs football game without issue. That's about 3 hours of use. I also use it as a stand alone speaker for keyboards in concerts and other indoor events. I have read several reviews on other pages griping about it randomly turning off. I'm pretty certain that's probably in it's design to save battery life. It does do that after a few minutes if it's not in use. When it's in use it's never turn off on me. I'm considering getting one for my man cave which is about 800 square feet. I think it will raise the roof on that thing. If you are thinking about getting a battery powered sound system definitely consider this on.

Great Speakers for Portability & Venues Without Electric Available - Impressive Battery Life & Sound a++
I have never owned a pair of Alto Speakers Before... I will say they are pretty cool / Versatile and sound pretty good for battery powered speakers. I get roughly 5 1/2 hours full volume battery life cranking music through them / House/ Freestyle / Rock ect.
If I am using them as a PA System just using mics I get roughly 6 1/2 Hours full volume. They are very easy to use with the bluetooth and sound pretty good, no complaints.

I also purchased a Mackie pro-fx battery powered mixer which allows me to be totally versatile at powerless venues or locations...

Amazing!
These speakers were exactly what we were looking for. As a church who has many outdoor activities throughout the year, we wanted speakers that were lightweight, easy to connect (wired and bluetooth), battery powered, and had enough power to pump music and use a microphone when we needed to make announcements. The batteries have exceeded our expectations. We ran them for three hours during two separate events and the batteries barely drained. I highly recommend these speakers to anyone!
