OVERVIEW
SAFETY NOTE
It is important that loudspeaker systems are used in a safe manner. Please take some time to
review the following points concerning safe use of XE Series loudspeakers:
•
Professional loudspeakers are capable of producing extremely high sound levels and should
be used with care.
•
Hearing loss is cumulative, and can result if people are exposed to levels above 90 dB SPL
for a long period.
•
Never stand close to loudspeakers driven at high level.
COAXIAL DIFFERENTIAL DISPERSION
®
TECHNOLOGY
XE Series monitors feature Martin Audio’s unique, patented Coaxial Differential Dispersion®
technology. The design augments the ‘point-source’ benefits of coaxial drivers with the
consistency of coverage which Coaxial Differential Dispersion® technology can deliver.
Non-coaxial systems can suffer from uneven frequency response in the crossover region because
of interference between the LF and HF sections; this causes off-axis variations, undesirable in a
stage monitoring environment. In contrast, coaxial systems aim to sum LF and HF contributions
at all positions off-axis, and over a range of distances from the loudspeaker.
A disadvantage of conventional coaxial devices can be HF beaming, where the HF dispersion
reduces at higher frequencies. This is primarily because the HF energy emerges through a
narrow tube in the pole-piece of the magnet system. Coaxial Differential Dispersion® drivers
overcome this by the use of a static waveguide that merges seamlessly with the unique cone
shape — maintaining the dispersion pattern even at very high frequencies.
A Coaxial Differential Dispersion® horn has a trapezoidal dispersion pattern in both vertical and
horizontal planes which covers the target area more evenly than a system with a conventional,
fixed-dispersion type horn. A conventional horn tends to produce an imperfect coverage pattern
which misses out some areas — particularly side areas close to the loudspeaker.
In contrast, a Coaxial Differential Dispersion® system as implemented in the XE Series produces
a near rectangular coverage pattern at head height. The consistency of frequency response and
SPL thus achieved throughout the target area is exceptional, and furthermore the area itself
is more extensive than with conventional monitors, allowing the performer a great deal more
flexibility of movement while remaining in the sound field.
