Pros: clarity, imaging, expandable to 5.1
Cons: needs more low mids
I have experienced a nicely sized 'comfort zone' with these speakers.
There is a slightly larger horizontal comfort zone than with my Mackie HR824's.
I was using these speakers in the studio but I wouldn't recommend them for reference monitors because the low mids sounded too attenuated to my ears.
An application where the MediaDesk will shine however is in a a den or a small room. These speakers are great for smaller spaces and low-level listening because at lower volumes the lower mid attenuation is much less noticeable. (re Fletcher-Munson curve)
The system also allows for an upgrade to a 5.1 set-up, with additional active amps being placed in the subwoofer casing.
Overall Blue Sky did a pretty nice job on these and after hearing them I am more interested in hearing Blue Sky's TOTL System One which is currently used in some big name movie production studios.
