Cogent field coil compression drivers

I have for sale a pair of the fabulous, world-class Cogent DS field coil compression drivers. These are, according to many horn experts, the best midrange compression drivers ever built by man. I certainly concur. A pair of them was at the heart of the finest audio system I ever heard, at Condition: 8/10 Very Good. This section looks at the three primary parts that go into constructing the Cogent True-to-life compression field coil drivers. This phasing plug is from their Cogent DS midrange / high frequency driver. The radial slits are cut to great accuracy with a wire EDM machine, a difficult and expensive process. The Cogent horns use field coil compression drivers patterned after the famous RCA drivers. The high frequency horn is a conical design from The Acoustic Horn company. For the lower frequencies a 10 foot J horn with an exponential flair is used.

There is a big thing (tempest in a tea cup) right now with people from LA to Germany and Japan taking Altec and JBL large and medium format vintage compression drivers and hot rodding them as field coils. Several things are cogent (pun intended) to this driver transformation- the actual structure of the permanent magnet driver and whether it can properly be converted to a field coil motor given its pole piece and the room within the casework for an adequate FC motor.
