Bessel Array
(White Paper) |
An improved Bessel array of electromagnetic
transducers, in which the Bessel coefficients (phase and/or magnitude)
are applied only in the useful high frequency range, where off-axis
interference patterns between the outputs of respective transducers
cause undesirable acoustics results. |

Single-Sided Bessel Array
(White Paper) |
An improved Bessel
Array of most commonly 5, 7, or 9 transducers. The Bessel coefficients
are applied only in a high frequency range in which off-axis
interference patterns between the outputs of the transducers are
meaningful. In lower frequencies, the transducers are driven more like a
simple line array, for improved bass output. |

Chamber-Loaded Augmented Passive Radiator |
A loudspeakers in which an electromagnetic transducer
drivers a chamber-loaded augmented passive radiator (APR). The
loudspeakers uses a bandpass enclosure such that the transducer produces
sound pressure directly into a listening space, and the APR produces
sound pressure into the listening space via an acoustic coupler through
a chamber which loads the large diaphragm of the APR. |

Compound-Driven Augmented Passive Radiator |
A loudspeaker in which a compound driver drives an
augmented passive radiator (APR). Either the compound driver and/or the
APR may be coupled to the enclosure in a high-pass configuration such
that is produces sound pressure directly into a listening space via an
acoustically coupled loading chamber. |

Loudspeaker Enclosure with Damping Material Laminated Within Internal Shearing Brace |
A loudspeaker cabinet with a laminated internal brace which reduces vibration, flexure, and expansion. These are damped by shearing forces applied to the damping layer as the rigid layers move in opposite parallel directions. |
