For sale, one pair of RCA MI-1428B field coil compression drivers.
If are aware of these, then you will be aware that these are some of the finest drivers available. These were refurbished and serviced by Steve Schell of Cogent a few years ago and fitted with custom made 8 Ohm (standard is 4 Ohm) Cogent carbon-fibre diaphragms.
Steve is a craftsman and even went as far as touching in the paint on the driver with a very close paint match. They have worked perfectly since the refurb and I am selling them due to a change in system direction.
One of the drivers has a slightly worn thread (you can see it in the photos), but works just fine. I mention it to ensure the description is as accurate as possible.
