Ugliness and initial disappointment aside, I actually have to applaud Martin Logan becuase they are really trying something new with this speaker.
The easy path for them would have been to replicate the looks of the old CLS and just replace the panel with the new X-Stat panel. Low risk, instant accpetance, but nothing that improves or modifies the current designs.
But in this case they are trying something novel with the bass portion of the speaker (Well, even if they borrow from previous electrostatic designs, it is at least something new for ML). So regardless of the looks, I think it is cool that they are really trying to advance the state of the art by doing something different with the bass panels, and not just settling for the status quo.
I think getting the bass right is probably what lead to such a long development time. Listening will show if it was worth the wait.
