System Features
The Samson Expedition system uses state-of-the art
technology to bring a revolutionary new degree of
flexibility and portability to professional audio. Its
main features include:
• A built-in telescoping handle and locking wheels
that make it easier than ever before to transport
your audio system.
• All Expedition enclosures are lightweight and
compact yet exceptionally durable and
roadworthy. Injection-molded with Polypropylene,
they feature substantial internal bracing to support
a nearly 1/2" thick side wall construction, making
them strong and rigid enough to allow maximum
energy to be delivered to the sound output.
In addition, a steel grill and scuff-resistant
textured finish makes for a rugged speaker
enclosure that will deliver dependable
performance in even the most demanding
environments.
• The low frequency section includes a custom
designed Kevlar-impregnated 12" low frequency
driver with a 2.5" Kapton Former voice coil and
50 ounce barium ferrite magnet for accurate and
super-tight bass response.
• A high frequency section that delivers clear,
sweet top end thanks to its 1" compression driver
with a specially designed phenolic diaphragm,
along with a phasing plug for linear response and
an elliptical wave guide horn design that reduces
nearly all sonic diffraction.
• A tilt position that allows the Expedition to be used
as an onstage wedge monitor.
• Integral 1 3/8" pole-mount receptacle and convenient fly points allow the
Expedition to be pole-mounted or “flown” using standard PA hardware.
• The EX10 is a passive cabinet that can be used with any power amplifier
rated at up to 250 watts into 8 ohms. It requires no power and provides
dual Speakon™ and 1/4" connectors that allow multiple EX10s to be
daisy-chained where extended coverage is required.
• The EX20 contains dual power amplifiers and an active crossover.
Operating in a biamped configuration, one power amp drives the low
frequency section with 150 watts of power and the other drives the high
frequency section with 50 watts of power. The active crossover uses an
advanced Linkwist-Riley constant phase filter that provides a steep rolloff of
24 dB per octave to reduce sonic distortion at the crossover frequencies.
Dual balanced XLR connectors allow daisy-chaining of multiple Expedition
enclosures, and a switchable limiter circuit assures a clean output even
when you’re pushing the EX20 to maximum levels. In addition, there are
three stages of speaker protection, including relay switching for power on
and off.
