Speaker upgrade around 100k retail

AudioMachina makes an active array that is unlike anything I have ever heard. External amplifiers of a completely unique design make this system completely unlike any system in existence. Only speaker to correctly handle amplitude vs. time (key to this are the amps I believe). Mounts in corners and significantly reduces the need for room treatments. 

Ascendo out of Germany makes a Model M speaker that was superb in its earlier iterations and has no doubt been improved. Rockports are always excellent.

A problem you face with large high end dynamic designs is the physical size of the cabinet. I always void mirror image designs with a woofer and midrange which is above a center tweeter/tweeters. Lansche is always a contender. 

Simple fact is that a crossover is a real problem and this component intrinsically limits any design which uses one. 

Yes you are correct, the Lansch speakers I have liked were the smaller models that were not mirror imaged (for want of a better term). 

Only heard the Alsyvox once at a show but they were very very impressive.
