Belated congrats on the speakers Art. Harbeth is the brand that seems to carry the most weight these days in the world of audiophile speakers, you go to Harbeth when you want the best. Period (within reasonable price points).
I liked reading about the realism of them, that they sounded like you were hearing the instruments / music and not speaker.
Can you comment about vocals? Male, female, rock, etc. Also about their capabilities playing rock music. Vocal image and clarity. Are the vocals focused and right there with you?
From the outside in, without hearing them, their design seems to have the built-in BBC dip, that British sound that so many of their contemporaries have. When you cross an 8" driver to a tweeter with no midrange in between, you typically violate a fundamental rule of thumb for speaker design, that being the 1/2 rule, where the next driver up the frequency chain should be no smaller than 1/2 the diameter of the lower driver. You do this to avoid beaming, distortion and / or suckout.
While I am sure Harbeth has done their best to minimize or eliminate any of those concerns, do you hear a trace of any of the above when compared to well designed 3-way systems?
