PROFESSIONAL SOUND SYSTEM
COMPRESSION DRIVER
HFD-260-8/16
DESCRIPTION
HFD-260-8/16
TOA's High-Frequency Compression Driver Models
HFD-260-8/16, in 8 ohms and 16 ohms versions, are
designed for use with in high level sound systems of
highest quality
such
as theaters,
auditoriums, churches, etc. It may be used with TOA's
LE series constant directivity horns and will provide a
high degree of efficiency and smooth frequency
response from 500 Hz to 18,000 Hz. The voice coil of
this driver is a 72mm (2.83") diameter, edged-wound
copper-clad aluminium ribbon coupled to a 50 micron
hard duralumin diaphragm. The diaphragm voice coil
assembly can be replaced in the field without assembly
uses self-aligning dowels for perfect centering in the
voice coil gap, which has a flux density of 22,000 gauss
generated by a 3.22 kg (7 Ibs.) ferrite magnet. A
machined phasing plug with three acoustic slots serves
as the pole piece and is utilized to provide the proper
phase relationship between the sound emanating from
the center and that coming from the edge of the
diaphragm/voice coil assembly.
FEATURES
1. Smooth frequency response
2. A flux density of 22,000 gause generated by a 3.22 kg (7 Ibs.) ferrite magnet (HFD-260-8/16)
3. High efficiency (SPL : 111 dB/W/m for HFD-260-8/16 and 110 dB/W/m for HFD-220-8/16)
4. Very high power capacity : 50 watts continuous pink noise (500~20,000Hz) for HFD-260-8/16
5. 49 mm (2 in.) dia. throat
6. Voice coil of edge-wound copper-clad aluminum ribbon
7. 50-micron duralumin diaphragm
8. Field replaceable diaphragm

uses self-aligning dowels for perfect centering in the
voice coil gap, which has a flux density of 19,000 gauss
generated by a 1.1 kg (2.4 Ibs.) ferrite magnet. A
machined phasing plug with two acoustic slots serves as
the pole piece and is utilized to provide the proper
phase relationship between the sound emanating from
the center and that coming from the edge of the
diaphragm/voice coil assembly.
