The
MacPherson M10PF is a full-bandwidth, multi-application loudspeaker that
excels in both audio quality and application flexibility. The primary
application for the M10PF is in overhead suspension applications.
Multiple threaded attachment points allow a variety of installations to
be accommodated. The very compact multi-angled cabinet design also
allows the M10PF to be used as a low-profile floor monitor or “wedge.”
The M10PF can also be stand mounted with the addition of an optional
pole-mount adapter. The 2-way design incorporates a sophisticated
crossover network, allowing a single amplifier channel to produce high
SPL with minimum frequency and phase anomalies. The internal components
include a 10-inch woofer and a 1-inch high-frequency compression driver
coupled to a constant-directivity horn. The high-frequency response
pattern is 60-degrees in both the horizontal and vertical axes.
The M10PF can be
effectively used for a wide variety of live and playback sound
reinforcement applications. These include corporate A/V, houses of
worship, theater, and theme parks. The M10PF is designed expressly for
use in single-cabinet point-source applications, including stereo and
split point-source configurations. The M10PF’s wide dispersion and
cabinet geometry is optimized for applications other than narrow
point-source horizontal arrays.
A
total of twelve threaded attachment (“rigging”) points allow the M10PF
to be used in numerous permanent and portable applications. An optional
“yoke” mounting bracket allows an M10PF to be supported horizontally.
The clean-lined powder-coated aluminum bracket offers two mounting
profiles. The normal mounting profile allows the cabinet to be adjusted
over a 360-degree range. The “tight” profile was provided for
height-limited (“tight hang”) applications, e.g., attaching M10PF
cabinets to a trade-show-related lighting truss. Two of the M10PF’s
attachment points are provided for attachment of an optional “pole cup”
mounting adapter. When used in floor monitor applications the M10PF’s
integral thermoplastic “skid plates” protect the cabinet’s finish.
Field experience has
proven the M10PF’s value. One user apologetically described the M10PF in
non-technical but real-world terms: “it’s really cute, and sounds
great!” While possibly not an endorsement that an engineer would
appreciate, it does confirm the M10PF’s successful design.
Major strengths of the
M10PF include its compact overall size and excellent audio quality. By
utilizing a high-performance 10-inch woofer the enclosure’s dimensions
could be scaled without compromising the desired audio quality. The
enclosure’s size and carefully designed proportions are such that it can
serve unobtrusively in many integrated overhead sound-lighting
applications, as well as finding use in floor “wedge” and various
utility situations. If the overhead suspension capabilities of the M10PF
are not required, please refer to the companion M10P.
The
M10PF’s audio performance is well behaved in both the frequency and
phase domains, resulting in superb voice and music reproduction. An
additional benefit is that unwanted interactions between loudspeakers
and live microphones are minimized. This can increase a system’s
gain-before-feedback performance. The M10PF also exhibits a carefully
controlled off-axis power response. This can reduce unwanted room
interactions, resulting in improved intelligibility and vocal clarity.
Carefully implemented bracing inside the enclosure minimizes the
generation of unwanted vibrations. Internal damping materials were
carefully selected for optimal performance. What’s the result when human
beings listen to the M10PF? A consistently positive reaction to the
audio quality both during controlled (demo) listening and actual use.
Inside and out, the
M10PF is a fully professional-grade product. The enclosure is made of
hardwood plywood, providing durability as well as minimal audio
resonance. The textured epoxy paint finish provides a rugged yet elegant
appearance. The M10PF’s low profile was designed to minimize obstruction
of sight lines. An integral handle provides assistance during
transportation and set up. Two NL4 connectors are located in a recessed
area of the cabinet, offering both aesthetic and functional benefits.
When describing a
product it’s important to point out its limitations as well as its
strengths. While the M10PF’s overall audio quality is very good, its
compact size and design criteria serve to limit its performance in the
low-frequency (sub-100 Hz) range. The M10PF’s design goal was for smooth
phase-coherent audio response, rather than extending the low end with
“tricks” such as aggressive filters or sub-optimal port-tuning. The
M10PF’s low-frequency performance should not pose a problem for the
intended applications. However in other cases, such as in front-of-house
applications, external subwoofers would generally be required. In
addition, the M10PF is also not designed for applications where extreme
SPL levels are required. For example, for rock n’ roll applications the
M10PF would not be applicable as a drum monitor. Does the M10PF go
“loud”? Certainly. But it’s not a high-power design in the absolute
sense. Again, the M10PF works great for its intended applications!
