We bought this for use in a church installation. We wanted a complete PA system with a sub and this fitted the bill perfectly.
It was about the only one of these type of column speaker that allows you to separate the two 'tops' and mount them on stands / brackets for stereo sound - which it the primary reason for selecting it.
The sound quality is amazing and the spread and projection of the speakers is nothing short of remarkable. Even at 90 degrees to the tops there is still a lot of clarity in the output, although at extreme angles you do lose a bit of the top end but, if you have a speaker cab at right angles to the person listening to it there is something wrong with your set up!
The whole package is compact, reasonably lightweight and incredibly well built.
For a portable (or permanent) setup i would not hesitate to recommend this product.
