PA261
Compact Two-Way Speaker System
The PA261 is an extremely versatile wide-dispersion,
low-profile, two-way loudspeaker system offering sub-
stantial power and value for a variety of professional
applications that include primary sound reinforcement
and supplementary fill for larger systems. Its sub-compact
size makes it ideal for low visibility column, side-wall
or under-balcony mounting. The high-frequency sec-
tion is a constant directivity horn loaded to a 1-inch
titanium diaphragm tweeter for smooth, wide dispersion.
The low-frequency transducers are two 6-inch carbon
fiber woofers suitable for difficult climatic environments.
The system includes a high-level crossover network
that features markedly lower (than conventional)
induction values in series with the woofer. We call
this innovation LICC (Low Impedance Compensated
Crossover). The benefit is delay reduction, reduced
phase shift and superior transient response. Dynamic
high-frequency driver protection is accomplished with
a fast-response filament resistor, chosen to comple-
ment the power curve of the driver.

Trapezoidal enclosure for array configurations
HF driver dynamic protection
The Mackie PA261 is a part of the VISION family of
loudspeaker products including full-range, cost-effective
two-way loudspeakers and complementary subwoofer
cabinets. These enclosures have a trapezoidal foot-
print for easy array configuration. All enclosures are
constructed using 19 mm void-free, birch plywood
and finished with a scratch-resistant black coating.
Transducer components are protected from the envi-
ronment by a heavy gauge metal grille. The VISION
products are eminently suited for fixed installation,
ready for suspension via built-in M10 inserts with
metal reinforcement and forged shoulder eyebolt hard-
ware. The PA261 also includes M8 inserts.

PA261Compact Two-Way Speaker System
Architects’ and Engineers’ Specifications
(continued Architects’ & Engineers’ Specs)
The two-way loudspeaker system shall be self-contained
and consist of the following components: (1) two 6-inch, low-
frequency drivers; (2) a high-frequency section consisting of
a 1-inch titanium dome tweeter; (3) a two-way crossover
network; (4) a vented enclosure.
The two low-frequency transducers shall be cone type loud-
speakers having cone diameters of at least 6 inches/152 mm.
They shall have voice coils of at least 3 inches/76 mm in
diameter and carbon fiber diaphragms. Together they shall
present a nominal impedance load of 4 ohms. Sensitivity
shall be at least 90 dB when measured at 1 m with an input
of 1 watt and the power rating shall be at least 200 watts
(AES), 800 watts peak.
The performance of the two-way loudspeaker system shall
be as follows: long-term power handling, at least 200 watts
rms; peak power handling, at least 800 watts; frequency
response, 60 Hz–15 kHz at –3 dB; maximum SPL, 119 dB
(anechoic–1m); sensitivity, 90 dB SPL (1W/1m anechoic);
–6 dB coverage, measured average 2 kHz–16 kHz, 100°
horizontal by 100° vertical. The two-way loudspeaker system
shall be a model PA261 manufactured by Mackie Designs.
The high-frequency section shall have a compression
driver with a titanium diaphragm of at least 1 inch/25 mm in
diameter. It shall present a constant-impedance load of 8 ohms.
It shall have a nominal coverage pattern of 100° horizontal by
100° vertical.
The system shall be crossed over by an internal, high-
level, passive network having a response of 12 dB/octave.
The nominal crossover frequency shall be 2.5 kHz. The low-
pass section of the network shall have minimum inductance
in series with the low-frequency drivers. A switch shall be
provided to disconnect the crossover network, but not the
high-frequency protection circuit, from the drivers to allow
bi-amp operation.
The enclosure shall be a vented design with an internal
volume of at least 0.83 cubic feet. The vent shall be tuned to
60 Hz. It shall be constructed using 0.75 inch/19 mm, void-
free birch plywood and finished with black, scratch-resistant
paint. It shall be trapezoidal shaped with 15° angled sides. A
full size, detachable, perforated steel grille, finished in black
scratch-resistant paint shall be provided. At least 9 reinforced
threaded metal sockets (M10, M8) for attaching mounting
hardware and three eye bolts shall also be provided. The
overall dimensions of the enclosure shall not exceed 24.0 in/
610 mm x 10.0 in/254 mm x 11.5 in/292 mm. Connections
to the loudspeaker shall be screw terminal connectors.
