LOW FREQUENCY LOUDSPEAKER
DESCRIPTION
The HLS46UL-8 is an 18" low-frequency loudspeaker
designed for professional applications in high level sound
reinforcement environments where high efficiency, super-low-
frequency range, and faithful reproduction are required,
such as studios, theaters, concert halls, auditoriums, discos,
and in live sound reinforcement applications.
The 46UL offers exceptionally high power handling capacity,
ultra-linearity in the super-low-frequency range, and a uni-
form frequency response from 20 Hz to 500 Hz. A crossover
frequency of 500 Hz or lower is recommended to obtain
smoothest overall system response. The loudspeaker em-
ploys a low-mass 4" (100 mm) diameter voice coil of edge-
wound copper ribbon on an aluminum coil form, which
operates in a flux density of 13,600 gauss. The voice coil is
driven by powerful double ferrite magnets, which are sup-
ported by a rugged diecast aluminum frame. The cone sus-
pension is made of exceptionally high compliance cloth
surround, damped.
