Harbeth P3ESR Anniversary edition. Worth the Upgrade?

What do you mean tweeter and driver spaced so far apart? What do you mean uncommon design decision? I use mine with a sub with great results!

Hi Yogi, distance between drivers is what I mean. Most 2 way designs have the woofer and tweeter closer to each other in physical proximity, presumably to create something closer to point source sound for coherence and imaging. 

Where are you crossing them over with the sub(s). Thanks! 

I high pass the sub at 80 hz to the Harbeths. I have tried running the Harbeths full range without using the high pass but they sound much better when I use a high pass filter!

I set my P3esr 40th up in my main system (temporarily set aside SHL 5+ 40th). I dialed in my REL Strata III at around 80 hz as did Yogiboy. Sounded great. The P3 was easier to integrate with the sub than the SHL 5+.

Wow- very nice valinar...Why do I feel this thread is going to cost me money (-: My second system consists of the following. Room is just over 11 feet square, but I have an 8 ft opening in back of my listening position.
