I've had them for a week and only have about 8 hours on them. They are a masterpiece of audio art and function. Heavy at 110 lbs each, once I got them into position, first listen was a real delight. Coming from a mint pair of Klipsch Chorus II's, they deliver with serious authority. The bottom is where the KC's were lacking.
The Luceras dig down to 32hz (KC's 39hz), with a tightness, chest thumping slam I so need to experience to feel satisfied with my system.
The mids and highs are very dynamic, airy, with great timbre and depth.
Overall, very natural with great presence. And they're not ever broken in yet!
I would post an image or two, but not as easy as some forums.
Greg is easy to work with, and he really knows how to build killer speakers, done right.
