Architect’s and Engineer’s Specifications
The two way high/low speaker system shall be a TOA SR-F1A, and the
sub-woofer system shall be a TOA SR-L1A, or approved equivalents. The
system shall be vented bass-reflex enclosures intended for portable system
applications, made of APITON plywood with FRP (fiber reinforced plastic)
system shall be vented bass-reflex enclosures intended for portable system
applications, made of APITON plywood with FRP (fiber reinforced plastic)
finish and a punched metal front grille. Input connections shall be via a
Neutrik NL4MPR connector.
The SR-F1A shall combine a low-frequency 30cm (12”) diameter/98dB
sensitivity cone speaker and a compression-driver equipped high-
frequency CD horn with 60° horizontal by 40° vertical dispersion and 110dB
sensitivity. Its power handling capacity shall be 120W RMS continuous pink
noise, band-limited to 50Hz-1kHz (low frequency), and 80W RMS
continuous pink noise, band-limited to 1 kHz-20kHz (high frequency).
The SR-F1A shall combine a low-frequency 30cm (12”) diameter/98dB
sensitivity cone speaker and a compression-driver equipped high-
frequency CD horn with 60° horizontal by 40° vertical dispersion and 110dB
sensitivity. Its power handling capacity shall be 120W RMS continuous pink
noise, band-limited to 50Hz-1kHz (low frequency), and 80W RMS
continuous pink noise, band-limited to 1 kHz-20kHz (high frequency).
The speaker shall weigh 38kg (83.8lbs.) and have dimensions of 390(W) x
619(H) x 362(D)mm [15.4” x 24.4” x 14.3"].
The sub-woofer system SR-L1A system shall have two 38cm (15”) diameter
cone speakers and 96dB sensitivity. Frequency response shall be 35Hz-
619(H) x 362(D)mm [15.4” x 24.4” x 14.3"].
The sub-woofer system SR-L1A system shall have two 38cm (15”) diameter
cone speakers and 96dB sensitivity. Frequency response shall be 35Hz-
1kHz. Its power handling capacity shall be 300W RMS continuous pink
noise, band-limited to 40Hz-1kHz. The speaker system shall weigh 81 kg
(176.8lbs.), and have dimensions of 829(W) x 629(H) x 602(D)mm [32.6” x
24.8” x 23.7”].
The electronic control unit for the SR-F1A and SR-L1A shall be the AC-F1
and AC-L1 respectively. When the AC-F1 is used, the frequency response
of the SR-F1A shall be 70Hz-20kHz, with a crossover frequency of 1kHz.
The AC-L1 shall provide the 125Hz crossover frequency for the SR-L1A.
Both electronic control units shall provide a crossover network with horn
equalization, component time offset correction, phase correction, an active
clipping limiter, and a crossover switch used when the SR-F1A is ceiling-
mounted.
