Any idea what it is? What size exit? Never heard of that term before.
Looks like its high end really drops away at about 12kHz but still impressive

The 140 dB figure is measured at one watt on a plane wave tube. Mounted on an exponential horn, it would appear that around 105 dB SPL (for one watt input ?) is the appropriate measurement for comparision with other drivers.

Thanks, missed that on the data sheet. Wonder what axiperiodic means (other than "Big driver")?

Paper Session P6
Friday, October 30, 9:00 am — 12:30 pm (Room 1A08)
Paper Session: P6 - Transducers—Part 2: Loudspeakers
Chair:
Sean Olive, Harman International - Northridge, CA, USA

P6-6 Wideband Compression Driver Design. Part 2, Application to a High Power Compression Driver with a Novel Diaphragm Geometry—Mark Dodd, Celestion - Ipswich, Suffolk, UK
Performance limitations of high-power wide-bandwidth conventional and co-entrant compression drivers are briefly reviewed. An idealized co-entrant compression driver is modeled and acoustic performance limitations discussed. The beneficial effect of axisymmetry is illustrated using results from numerical models. Vibrational behavior of spherical-cap, conical, and bi-conical diaphragms are compared. Axiperiodic membrane geometries consisting of circular arrays of features are discussed. This discussion leads to the conclusion that, for a given feature size, annular axiperiodic diaphragms have vibrational properties mostly dependent on the width of the annulus rather than it's diameter. Numerically modeled and measured acoustic performance of a high-power wide-bandwidth compression driver using an annular axiperiodic membrane, with vibrational and acoustic modes optimized, is discussed.
