I feel the JBL A130 is one example. Very good above 55hrz, quite low in distortion (and subjectively I though sound excellent) and on sale a pair of complete speakers costs less than 1/2 of one bare purifi woofer. I'd say if you are going to use a sub/subs then the purifi is really hard to value. Though compression is not measured here.Sure, maybe it's not, but it's got a flat response and THD below 5% from 40Hz upwards at 86dBSPL, in a small package. Can you point to other speaker measurements that cause you to say it's not special?
The A130 can be Eq'd to a 6+ harman score with 8+ using a sub as well.
(not saying I am not impressed with this speaker - I am, just not as sure about the woofers due to price)
