Ok I'm setting out to be very fair with this review. The radio station I work for has a couple of sets of these so I knew what I was getting before I ordered them.
Firstly the good:
The speakers (because that is what they are) are powered and are absolutely perfect as computer speakers or for connecting to a mobile phone, for use as AirPlay or similar via a receiver. They are reasonably priced and offer sound comparable to JBL Control One speakers without the outlay of an amp.
The sounds quality is not of monitor standard, so the name is misleading. However the sound quality is not bad, frankly you are getting what you pay for. The bass response of these speakers is adjustable officially by the bass knob. What you are actually getting is an adjustment of the low end of the midrange as the actual bass response is quite poor.
Lastly and most importantly, the RF shielding is shocking. Believe me you will know when your mobile phone is anywhere near these.
I paid £45 for these as an Amazon Warehouse item and I am happy enough, despite the shortcomings.
Mine are wall mounted using a pair of £15 brackets from Maplin which do well enough. Side clamp speaker brackets may not be suitable because of the curve of the lower portion of the speakers.
