Having had these for a couple of weeks now we are very impressed. Easy to set up - 5 mins, and easy to use. Sound and clarity is superb, everything we have come to expect from Turbosound gear - we also run a large Flexarray system too. Gain calibration is a little confusing as 0db is not 0db. Bluetooth set up is easy and quick, like the linking feature which handles stereo well. Two separate channels on the back of the sub with links out to connect to additional speakers if needed. Remote control app for iPad/iPhones is good for accessing all features, would like to see the app show values though Pro's - great price, great sound although some EQ is required as the mid-Hi's are quite pronounced, also needs a little sub boost for balance but this will depend on where you position them. Cons - you definitely need to purchase transport bags for the tops as would get scruffy in time without. The tops only connect with 4 short metal lugs, would have been better to have some means to lock them together. If you are looking for a great sounding, very portable, easy to set up system for acoustic / solo / DJ work then look no further these are excellent. Highly recommended.
