I used a set of Model 32s on my repair bench in the 70s. They took more punishment from the wayward amps, turntables and tape decks that did all sorts of surprising things like oscillations, pumping, motorboating, blurps, snaps, etc. Those little speakers took it all and went right on. Quite hardy.
Sonically, they tended to compress quickly when fed with lots of power. That is, you could push them to a point and then they would just not get any louder. Mind you, by this time, they were getting loud. Yes, the woofers and small cabinets mean there's not a lot of deep bass but they were one of what I would consider a _real_ bookshelf speaker: small but with quality reproduction best for small jazz and quartet music and in a small room.
Cheers,
