Rated 5 out of 5 by from Top quality product.These speakers were installed in a set of 30 year old 380 se cerwin vegas as the midrange,they have made the vegas sing again.The 6MD38 mids are well worth the money.

Rated 5 out of 5 by from Very clear sound excellent dynamicsI researched by specs before purchase, and used them in a 3 way sealed cabinet. 700 Hz /5.6 kHz crossover with CAT 378 and acoustically isolated ST385-8. I'm blown away by the clear and loud sound, amazing dynamics and stereo image. The other speakers from the cabinet must match the 96 dB SPL of these.
