I'm planning on checking these out at CAF next weekend. I hope they sound good. I briefly owned a pair of the Spatial Audio Lab X5 speakers and they sucked. The AMT tweeter was brutal, it didn't blend well with the other drivers and constantly called attention to itself. I owned them for 2 or 3 months and I couldn't take it any longer, they had to go. I believe these are more akin to the Spatial Audio M5 Sapphire which I've never heard.
New speakers unveiled from Clayton Shaw - Caladan
As I understand it, Clayton developed these speakers after he parted with Spatial Audio. At a cost of ~$3K, which is astounding, and a beautify wood baffle, they look sensational. I heard the sound of them in the video below on my cans and was super-impressed. They go very low in response as well. I can't wait to hear more reviews of them as I am sure that they will be excellent performers for a really affordable price. You have lived until you have had OB speakers in your room, which is just my humble opinion.
