[013] Title: Phase Plug Modeling and Analysis: Circumferential Versus Radial Types
Author: Clifford A. Henricksen

Abstract: Mechanical modeling of a simple phase plug yields an electrical-mobility equivalent circuit; a single-frequency notch filter. This applies directly to "normal" circumferential-slit configurations. The analysis is then applied to a radial-slit phase plug,

Abstract: Mechanical modeling of a simple two-dimensional phase plug and diaphragm yields an electrical mobility equivalent circuit; a two-pole, low-pass filter. At higher frequencies, this analysis becomes incomplete, and a model presented by Merhaut (1975) is us

Abstract: The war of the phasing plugs still rages after more than 25 years. Compression driver phasing plugs have vacillated between annular rings, salt shakers, teardrops, and now radial slots again. When Bob Smith provided simple design criteria for
[016] Title: The Dual Coil Inductively Coupled Loudspeaker System Performance Optimization and the Application of an Acoustic Phase Correction Plug
Author: Boaz Elieli

Abstract: Analysis of the dual coil inductively coupled loudspeaker system using an electrical equivalent circuit is presented, and some of the practical design aspects relating to the system optimization are discussed. The application of an acoustic phase correct
[017] Title: Ultimate Performance of Wide-Range High-Frequency Compression Drivers
Author: Clifford A. Henricksen
Publication: AES-J, Vol. 24, No. 8, Pg. 639 (1976)
Publication: AES-P, No.1126, Cnv. 54, (May-1976)

Abstract: Performance equations are developed from an electric mobility model of a typical electromagnetic compression driver. The analysis is independent of impedance and relates ultimate performance to material, air, and phase-plug variables.
[018] Title: An Investigation of the Air Chamber of Horn Type Loudspeakers
Author: Bob H. Smith
Publication: ASA-J, Vol. 25, No. 2, Pg. 305-312, Mar-1953
URL: none
Abstract: The front air chamber design is treated as a boundary value problem which yields a solution of the wave equation for the general case in which the horn throat enters the air chamber in a circumferentially symmetrical manner.
[019] Title: Tweeter Design Considerations
Author: George W. Sioles
Publication: AES-J, Vol. 4 No. 3 (Jul-1956)
