I listened to 901s extensively in the 70s and 80s (mostly discos but some friend's houses, too.) They had no bass and very shelved down highs. The two discos that used them had supertweeters and subwoofers also and used the Boses pretty much for midrange. When I've heard them at houses they've always sounded shouty and veiled at the same time. Phasey, too.
I'd go to your local Guitar Center and check out some pro speakers, both studio and reinforcement types.
