The R44CX has 6dB more output than the original RCA 44BX. It has the same museum-quality shell, but is distingued by a red and silver emblem, and comes with the same cable and accessories.

The AEA R44 series microphones all share the authentic sound, feel and look of the 1936-38 RCA 44BX. They combine the 1930s US sound with British engineering from RCA that reduces the mic's weight and hum sensitivity. The R44 series microphones are all hand-crafted replicas in detail, using parts that are made to be interchangeable with an original RCA 44, even featuring ribbon material originally manufactured for RCA. The R44C was designed to meet or exceed the output of an RCA 44 when it was new. The R44CX is a high-output version of the R44C especially designed for scoring and other applications demanding a wide dynamic range with the "classic 44" sound.
