Purchased several of these to use as on stage foldback for a Church. We were having problems as the room we use was very reverberant, so wanted to b able to lower the level of on stage sound. By having more smaller speakers, closer to the musicians we were able to achieve this. For the cost, they are perfect for what we required.
They mount well on either short or tall mic stands and can be angled to point at your ears nicely. Nice choice of inputs (XLR, Jack, RCA), and able to daisy chain them. Volume control on the back so individual can change the overall level of their mix, but not too obvious so as to have people constantly tinkering with them. As they are quite compact, they are not obtrusive on the stage.
They are quite heavy, so make sure the stand you put them on, if doing this, is not too flimsy, and that you make sure you do all the adjusters on the stand up tight, or you may find the speaker moving!
Overall, for what we wanted to achieve, these have done the job really well, and value wise are perfect. The quality of the product, and the quality of the sound from them is ideal for our situation.
