The
MacPherson M10P is a full-bandwidth, multi-application loudspeaker that
excels in both audio quality and application flexibility. The very
compact multi-angled cabinet design allows the M10P to be used as a
low-profile floor monitor or “wedge.” The M10P 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
M10P 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 M10P is designed expressly for
use in single-cabinet point-source applications, including stereo and
split point-source configurations. The M10P’s wide dispersion and
cabinet geometry is optimized for applications other than narrow
point-source horizontal arrays.
Field
experience has proven the M10P’s value. One user apologetically
described the M10P 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 M10P’s successful design.
Major
strengths of the M10P 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 floor “wedge” and
utility applications. When stand-mounted the M10P offers a pleasant
alternative to larger, sight-line-impacting cabinets. It’s important to
note that the M10P is not intended for overhead suspension applications.
That’s a role filled by its companion product the M10PF.
The
M10P’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 M10P 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 M10P? A consistently positive reaction to the audio
quality both during controlled (demo) listening and actual use.
Inside
and out, the M10P 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 M10P’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 M10P’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 M10P’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
M10P’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 M10P is also not designed for applications where extreme
SPL levels are required. For example, for rock n’ roll applications the
M10P would not be applicable as a drum monitor. Does the M10P go “loud”?
Certainly. But it’s not a high-power design in the absolute sense.
Again, the M10P works great for its intended applications!
