The theoretical problem is in the power response. A two-way with a 10" driver covering the midrange needs directivity control to have a reasonably uniform power response. I know the crossover point for the A-25XL was 1500 Hz, and I think the A25 might be higher but I'm not sure. That's about an octave above the point where 10" cones start becoming directional. The result is a dip in the upper midrange in the power response which gives the speaker a mellow and laid back character. The large-ish tweeter was also directional at the top of its range, so I would imagine it lacked energy in the top two octaves. I've not heard the original A25, only a Seas kit.
By late 1960s standards, it may have been a very fine speaker. But by modern standards, it's a stupid design and I don't know why people keep cloning it. Nostalgia I guess.
