I don't think audiophiles ever considered 901's a high end speaker. J.Gordon Holt trashed them in his Stereophile review when they were introduced. I saw/heard them in two stores in the Santa Clara Valley in 1971---in the "best" room at Pacific Stereo (N. California's leading Hi-Fi chain in the late 60's/70's) in Mountain View, where you could compare them with the AR-3a and JBL L100 (which I did), and in an early true high-end shop, Sound Systems in Palo Alto, where I heard them against speakers from some new company named Infinity (which I also did).
In both stores the 901's sounded just as Gordon described them---a big amorphous blob of sound. Terrible, just terrible. The AR-3a was a pretty withdrawn, distant sounding speaker, yet considerably better than the Bose. The JBL L100 was the opposite of the AR, being very forward and brash. Still, not as bad sounding as the 901. At Sound Systems, even the $139 Infinity 1001 (the lowest priced model in Infinity's 1971 line up) was a far better speaker than the Bose. And Infinity's 2000A (at $299 each, close to the $500/pr Bose) absolutely mopped the floor with the Bose. Then there was the Infinity Servo-Static, at $2000 (which would also buy a brand new family sedan) not a fair comparison. But it did show me how good a speaker could sound. Being a young starving musician, I bought the 1001's, for about half the price of the 901's.
