Pro700Mk2 to me was everything wrong with ATs older sound in the opposite direction. Instead of the overly sharp older peaky house sound. These was the complete opposite in that they were too dark and lacked any real detail. It was ATs attempt at Bass heavy monitor. No offense but I hated that can..Dark, slow bass signature is one thing but too much bass with mids and highs that float on the bass with little definition is not my idea of a good bass can.
The WS99 will give you some extras with your bass. These will be somewhat tame compared to the Pro700MK2s sheer quantity of bass.. But will be very satisfactory in a new direction. Hows about some quality fast bass for once.. Hows about some nicely detailed highs and very nice deep mids where most of your music comes from. See this is the area that most bass cans just can't get it right but the WS99 shines here in spades. To me this is a bass can done right.. You can do more than just bass heavy music on these. Not so much on the ProMK2s..The Pro700MK2 remain the only can that I returned from AT ever..The WS99 is on a completely different level over the MK2s in over all quality of sound including the bass.
Where the WS99 will lack in quantity vs MK2s, it will make up for it in letting you actually hear what your music should sound like. If your curious about getting these. These are what the ProMk2s should have been. Give them a try it will surprise you just how much better the WS99 will sound for all your music..Dynamics such as speed, clarity, detail, and depth. can described the sound on the WS99.. ProMK2? I don't think so.
