The Control 1TM is a high performance
personal monitor loudspeaker.
Incorporating a 5¼" (135 mm) low
frequency loudspeaker, 3/4” (19 mm)
high frequency radiator and high
performance dividing network, the
Control 1 provides full-range, low
distortion reproduction in a variety
Compact and durable, the Control 1
performs equally well in recording
studios, mobile audio video control
rooms and broadcast studios. It is also
highly suitable for foreground and.
background music use in restaurants,
discotheques, and audio-visual
HF and LF transducers are magnetically
shielded, permitting the
Control 1 to be used in close proximity
to video monitors. Well balanced
sound and exceptional power
handling make the Control 1 ideal for
any installation requiring professional
control monitor performance from a
Control 1 mounting versatility is
enhanced by a complete line of

Control 1 Miniature Loudspeaker System
Wall/ceiling mounting brackets are available for permanent
attachment to any rigid surface. A clamp mounting
system is available for semi-permanent attachment to a
wide variety of structures.
Additionally, mounting adaptors are available to interface
the Control 1 system to other menu systems now in
use as well as photographic tripods or microphone stands.
The loudspeaker system shall consist of a 135 mm (5¼ in) lowfrequency
transducer, 19 mm (¾ in) dome high-frequency transducer,
and frequency dividing network installed in a ported enclosure. The
magnetic assemblies shall use ferrite magnets, with integral shielding
of the external magnetic field. The low frequency voice coil shall be
25 mm (1 in) in diameter. The frequency dividing network shall have a
crossover frequency of 6 kHz and shall utilize polypropylene bypass
capacitors to reduce hysteresis effects on the signal.
Performance specifications of a typical production unit shall be as
follows: measured sensitivity (SPL at 1 m (3.3 ft) with 2.0 V input,
swept from 500 Hz to 2.5 kHz) shall be at least 87 dB SPL. Frequency
response shall be within plus or minus 3 dB from 120 Hz to 20 kHz.
Usable frequency response shall extend downward to 70 Hz. Nominal
impedance shall be 4 ohms, Rated power capacity shall be at least 150
watts continuous pink noise, based on a test signal of filtered random
noise conforming to international standard IEC 268-5 (pink noise with
12 dB/octave rolloff below 40 Hz and above 5 kHz with a peak-toaverage
ratio of 6 dB), two hours duration.
The entire enclosure shall be manufactured of molded polypropylene
structural foam. Optional mounting brackets shall be available
for positioning of the loudspeaker at various angles for both temporary
and permanent installations, Overall dimensions shall be no
greater than 235 mm (9¼ in) by 159 mm (6¼ in) by 143 mm (5 5/8 in)
deep. Finish shall be black or white, with metal grille and rubber end
