Thanks for inquiring I feel this works as a personal monitor but not to sure it would hold up for a Duo. For the price of this I'm sure you could get a nice wedge monitor that would benefit better to your needs. Hope this helps. And best of luck on your musical journey my friend.

Thanks for taking the time to write in. This is definitely not a match for the street cube. It's more of a monitor I believe. But if your just playing a small venues It would work for guitar and vocals. . However you'll need some kind of board to run it through if you wanted to run backing tracks it doesn't have an Aux input. And is not blue tooth compatible. That's why I use it with the boss ve8. Hope this is helpful. Thanks again and happy gigging.

@@ttaurus393 right there are no reviews that show someone playing with it with a small crowd. So I’m prone to wait until I can get S1. There is a model where you can store backing tracks and select them that interests me but not at the price of not being heard in small gatherings outdoors.

I agree the Bose s1 pro is the way to go it has Bluetooth 2 channels with independent eq a 3ed channel for backing tracks. And can play well to a small or medium venues. We'll worth the money. This product in this video is best for just a monitor. If your tight on money at the moment may I suggest zzsounds. Com this is a music company that let's you make payments on gear. It's called pay as you play. Hope this is helpful.
