djk Posted February 10, 2002 Share Posted February 10, 2002 The K57 is a 1-1/2" voice coil phenolic midrange driver, crossed at 600~700hz in various models and 6Khz to the tweeter.There are three K55 phenolic midrange drivers, all have 2" coils and were crossed at 400~700hz in various models.The K55V with the push button terminals is the most common, the K55V with solder lugs had a two port phase plug for better HF in the 4~6Khz range, the K55M was a ceramic magnet copy of the latter.There are a few K51V that mainly found their way into Cornwalls, these look to be a K55M made by the vendor that made the K55V.
