X2. I have 4’s from the early 80’s that had the speakers refreshed/updated about 8 years ago. I have a narrow very deep room (about 15 x 40 with a hallway and rooms opening off one side). Speakers are against the front 15 foot wall about 18 out from corner walls. Sounds the same anywhere unless you are seated on a sidewall less than 8 feet from a speaker. Even there, the tweeter from the opposite corner is directed more to your position. Great solution if you can’t set up a proper listening space in a living/family room.
They have me buying 70’s funk, Talking Heads, and Brian Eno, but Gillian Welch sounds just as good. On the Smithsonian Folkways Lucinda Williams “Happy Woman Blues”, you can hear the size of the room she is singing in, no matter where on the long couch or what chair I’m sitting in.
I haven’t had better speakers to compare them too, but doubt I ever will, other than someday maybe newer Ohm Walsh. PSA have unfortunately priced themselves out of my range against something I know works in my space.
