Welcome to Samson Expedition—the portable audio system for the new millennium! This exceptionally
versatile system offers the perfect solution wherever you need portable, high-quality audio: as a main PA
system or as onstage monitors in clubs and performance halls; in houses of worship; as a sound system
for business presentations, mobile DJs at parties, or aerobics instruction; and for use in outdoor environ-
ments such as parks, beaches and flea markets. What’s more, every Expedition system comes with a
built-in telescoping handle and wheels, making it easy to take professional audio with you wherever you
go!
There are three different Samson Expedition systems detailed in this manual. All utilize the same light-
weight yet rugged two-way speaker enclosure that pairs a custom designed 12" woofer with a matched
1" compression driver. The Expedition EX10 is a passive 8-ohm enclosure that can be used with any
external power amplifier rated at up to 250 watts. The Expedition EX20 is a powered version that
includes a bi-amped power cell along with an active crossover, speaker protection circuitry and built-in
limiting. And the Expedition EX30 is designed as a total all-in-one portable PA system, adding a four-
channel stereo mixer—complete with digital effects—to the equation. In addition, a number of expansion
options are available, including a 500-watt active subwoofer (our EX500); a rechargeable Lead-Acid
GelCel battery pack; and a rear-panel mountable cassette recorder with pitch control. There's even a
prewired custom compartment that accommodates any of three different Samson wireless receivers!
