About the Changeling 115
The James Romeyn / AudioKinesis Changeling 115 is a high-sensitivity, 15-inch bass loudspeaker cabinet designed by AudioKinesis and sold through James Romeyn Music and Audio. It combines a custom 4-ohm Kappalite-based woofer with front- and rear-firing midrange output, allowing the cabinet to produce a more spacious, acoustic-style presentation than a conventional forward-firing bass cabinet. User controls provide several voicing options for room and stage conditions, including selectable port loading, high-frequency voicing, upper-mid character, and reduced rear-mid output. The manufacturer describes the cabinet as offering three ported alignments plus one sealed configuration, with the rear pair of midrange cones switchable to a 7 dB lower level. Published information does not provide complete driver-by-driver electrical data, distortion figures, maximum SPL, crossover details, or a precise full-range frequency-response curve beyond the stated low-frequency point.
