SP400C
The SP400C is a complete two-way bass-reex
ush-mount loudspeaker assembly designed for xed
installations into typical ceiling plenum spaces. Employ-
ing a unique HF waveguide design based on our HR824
studio monitors, the SP400C delivers superior dis-
persion and pattern control over conventional coaxial
designs. The waveguide integrates the HF driver with a
6.5" LF driver optimized for smooth frequency response
and seamless transition through the crossover point.
The result is extraordinary acoustic performance not
generally associated with a commercial ceiling speaker
in this price range.
The SP400C is supplied fully assembled, complete
with a sealed zinc-coated steel backcan and cam-style
installation clamps. The metal enclosure includes a
recessed Euroblock input connector with detachable
mating plug, concealed behind a hinged metal cover
plate. A welded tab is provided for seismic restraint. Two
steel T-Bar support channels are provided to facilitate
installation to a standard tile ceiling. Also supplied is a
steel split C-ring, which serves to disperse the clamping
pressure of the mounting cams.
The SP400C is supplied with an integral 70/100V
line transformer rated to a maximum of 30 watts. Power
is adjustable by means of a recessed rotary switch on
the front bezel, and allows selection of 30, 15, 7.5 and
3.7 watt taps. A second recessed rotary switch is pro-
vided to engage a 16-Ohm tap for use with low-imped-
ance ampliers, or a 150 Hz high-pass lter, allowing
the SP400C to be used as either a full-range speaker for
stand-alone applications or as a satellite speaker when
used with the SP800S subwoofer.
The speaker assembly is shipped with a detachable
plastic cover tted over the transducers inside the
bezel. This protective cover protects the drivers from
damage during installation and also serves as a paint
cover, allowing convenient spray painting to match
interior décor. A powder-coated perforated steel grille
is supplied, and easily installed once the desired
Tap Selector and Full-Range/High-Pass switches have
been set.
The entire assembly is fully tested at the time of
manufacture and is warranted to be free from defects
in materials and workmanship for a period of ve years
from the date of purchase. The speaker is designed for
use in ceiling plenum spaces and meets UL 1480 and
UL 2034 regulations governing signaling devices and
plenum applications.

Mackie Designs continually engages in research related to product improvement. New material, pro-
duction methods, and design renements are introduced into existing products without notice as a
routine expression of that philosophy. For this reason, any current Mackie Designs product may differ
in some respect from its published description, but will always equal or exceed the original design
specications unless otherwise stated. ©2002 Mackie Designs Inc. All rights Reserved. Mackie and

The two-way, full-range loudspeaker system
shall incorporate one 6.5-inch low-frequency (LF)
transducer and a 1-inch, damped soft-dome high-
frequency (HF) transducer. The HF driver shall be
mounted on an exponential waveguide providing
high-frequency pattern control beyond 10 kHz. The
LF and HF drivers shall be mounted in a vented,
combination injection-molded bezel and steel enclo-
sure tuned for optimum low-frequency response.
The system shall have a nominal coverage pat-
tern of 110° at 8 kHz and 130° at 1 kHz. System
frequency response shall vary no more than ±3 dB
from 89 Hz to 20 kHz measured on-axis.
The speaker system shall be used in 70-volt
or 100-volt distributed audio systems in full-range
or high-pass mode. A front-mounted rotary switch
allows use of the speaker system in applications
where it is desirable to use the device above 150 Hz
only. A third mode of operation shall allow for use
of the system in full-range mode in low-impedance
applications.
The speaker system shall be designed for use
in either acoustic ceilings or drywall-based walls
or ceilings with the use of the included mounting
hardware or additional accessories. The front of
the loudspeaker shall be covered with a powder-
coated, weather-resistant perforated steel grille.
The assembly shall be UL and CE certied (UL1480
and UL2043).
The two-way full-range loudspeaker system shall
be a Mackie Designs SP400C.
