Used in a small venue for all audio needs these active speakers have proven their ability to deliver believable choral and organ music alongside meeting the need for PA and disco. The install is permanent on brackets rated well above the weight on these. Listeners all comment how the clarity is maintained from low to very high volume with no need to adjust levels. Very pleased. Pros: huge vale for money, fantastic versatilty, relatively small size, great protection circuitry, good connection versatility, great sound dispersion angles horizontal and vertical so listeners up close dont feel it is too loud and furthest people say loud enough. Cons: Heavy but not too heavy, No way to fit protection to corners of what are plastic cabinets... not a big worry as they feel rugged and we have them fixed in place most of the time. No way to lock out settings from being played with - would be nice to be able to protect the levels once set either behind a cover or a key switch to keep public fingers from playing. Overall a great buy with no major drawbacks and will recommend to clients again.
