Green Mountain Audio has been producing fine loudspeakers out of Colorado for some time now. Over the past several years I have been lucky enough to test drive the Eos HD in my system.
The Eos HD is a 2 way time coherent* monitor which employs a 1st order crossover design. This is achieved when the tweeter and mid range speaker driver move in unison or synchronously. Being made of a composite marble material helps dampen cabinet resonances while also allowing the designer to shape the cabinet in more acoustical appropriate ways. Bottom line: The Eos HD produces music with excellent imaging/localization and a transparency that is truly amazing.
*The best comparison I can give to experiencing time-coherent speakers is listening to a DAC (digital to analog converter) with extremely low jitter through headphones such as the Sennheiser HD-600. Since most headphones have one driver per channel, time coherence is built into the design. While a good pair of headphones and a DAC can reproduce digital music with great results, the experience is very different from sound produced over loudspeakers.
Note: I was able to hear the Lindemann BL-10 at T.H.E. show last year and was very impressed with the sound of this 2 way speaker (employs a simple crossover design for minimum phase). I have not had extensive listening sessions with the Lindemann, but hope to review it in full in the future.
