H-3 / H-3WP
The speaker shall be a two-way, sealed enclosure suitable for wall-mounting. The speaker shall
have an external appearance that is visually pleasing and blends well with surrounding building
architecture and fixtures. Speakers requiring visible external mounting brackets shall not be
acceptable. The loudspeaker shall utilize high quality components with Neodymium magnets for
high power handling. The high frequency component shall be a 1" dome tweeter and the low
frequency components shall be dual 4" cone woofers. The speaker shall be compatible with low
and high impedance speaker systems and shall include a built-in 70.7/100 V matching
transformer with the following selectable tap settings: 30 W, 15 W, 7.5 W, 3.75 W (70.7 V) and 30
W, 15 W, 7.5 W (100 V). The speaker shall also have selectable impedance settings of 8 ohms
and 16 ohms. The output sound pressure level at a distance of 1 m with 1 W of input power
applied shall be 89 dB SPL. The rated power handling (Continuous Program) shall be 150 W at 8
ohms and 30 W at 16 ohms or with matching transformer. The speaker shall have a frequency
response from 100 to 20k Hz. The speaker shall employ a high quality internal passive crossover
circuit with a crossover frequency of 4k Hz with optimized filter slopes of -12 dB per octave low
pass filter and -18 dB per octave high pass filter. The speaker shall include a removable terminal
block connector, screw terminal type, with loop-through terminations and accept AWG #14 - #24.
An internal protection circuit shall prevent damage to the high frequency component in an
overload condition. Once activated, the circuit shall reduce the input signal and reset
automatically after approximately ten seconds once overload condition is removed. The speaker
grille material shall be rolled steel plate (H-3) / stainless steel (H-3WP) with a paintable white
finish. The speaker enclosure shall be fire-resistant ABS resin with UL94:V-0 rating. Dimensions
shall be 11.6” x 12.5” x 5.1” (295 x 318 x 129 mm) and weight of 7.3 lbs. (3.3 kg).

The loudspeaker shall be TOA model H-3 / H-3WP.
The optional equalizer module shall be TOA model E-06R.
