and of course I had to lookup some of my non-JBL speakers.

quotes:

ADS L1290

After only a brief exposure to the ADS L1290's in our listening room, however, we had no doubt of their superior sound quality. The subsequent validation of this judgment by our test instruments was a reassuring demonstration that sometimes speakers measure the way they sound!

The L1290 has an unusually flat and smooth response over the full audio range and a half octave beyond, excellent dispersion in the forward hemisphere, and bass distortion lower than that of any common program source except a digital tape or disc. It is a genuinely fine speaker that is representative of the current state of the art in dynamic speaker-system design.

OHM Walsh's:

The Walsh was a very fine-performing unit. Its sound was surprisingly neutral, to the point that we were hardly aware we were listening to speakers, and this is one of the greatest compliments one could pay to a loudspeaker.
