Harbeth P3ESR Anniversary edition. Worth the Upgrade?

Definitely reaching the laws of diminishing marginal returns. A $600 upgrade for a ~5% improvement. No doubt these will be collectible though and hold their value.

Does anyone know what the crossover point is? I’m guessing it’s pretty high with that .75 tweeter. 

Also, why is the tweeter and driver spaced so far apart? I’m sure there is good reason, its just an uncommon design decision. 

I rarely hear of folks using these with subs. The sealed box would be easier to blend vs a ported design. 

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!
