Vision Series
Compact Two-Way Speaker System
PA261

The PA261 is an extremely versatile wide-dispersion,
low-pro le, two-way loudspeaker system offering sub-
stantial power and value for a variety of professional
applications that include primary sound reinforcement
and supplementary  ll 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
 ber woofers suitable for dif cult 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 bene t is delay reduction, reduced
phase shift and superior transient response. Dynamic
high-frequency driver protection is accomplished with
a fast-response  lament resistor, chosen to comple-
ment the power curve of the driver.

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 con guration. All enclosures are
constructed using 19 mm void-free, birch plywood
and  nished 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  xed installation,
ready for suspension via built-in M10 inserts with
metal reinforcement and forged shoulder eyebolt hard-
ware. The PA261 also includes M8 inserts.

This Mackie product is covered by an exclusive, one-
time, NO FAULT repair policy in addition to a  ve year
limited warranty.

Architects’ and Engineers’ Speci cations
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  ber 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 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  nished with black, scratch-resistant
paint. It shall be trapezoidal shaped with 15° angled sides. A
full size, detachable, perforated steel grille,  nished 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.
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.
