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.
