Low Frequency Loudspeaker Model HLS46S-8

APPEARANCE

GENERAL DESCRIPTION

The HLS46S-8 is a 460 (18 in.) low-frequency loud-

speaker designed for professional applications in high

level sound reinforce ent environ ents where high

efficiency, supper low frequency range, and faithful

reproduction are required, such as studios, theaters,

concert halls, auditoriu s, discos, and in live sound

reinforce ent applications. The HLS46S-8 offers excep-

tionally high power handling capacity, ultra linearity in

supper low frequency range, and a unifor frequency

response fro 20 Hz to 3,000 Hz. A crossover frequency

of 1,000 Hz or lower is reco ended to obtain s ooth-

est overall syste response. The loudspeaker e ploys a

low- ass 100 (4 in.) dia eter voice coil of edge-

wound copper-clad alu inu ribbon on an alu inu

coil for , which operates in a flux density of 13,600

gauss. The voice coil is driven by a powerful ferrite

agnet, which is supported by a rugged diecast alu i-

nu fra e. The cone suspension is ade of exception-

ally high co pliance cloth surround, da ped.

FEATURES

1. S ooth, extended supper low frequency response

2. High power handling capacity : 600 watts continuous

pink noise (AES Standard)

3. High efficiency and ultra linearity in super low range

4. Low distortion

5. Voice coil of edgewound copper-clad alu inu

ribbon, with an alu inu coil for

6. Powerful ferrite agnet structure

7. Rigid diecast alu inu construction
