Samurai – Natural Sound's Samurai "is a 94dB efficient three-way loudspeaker capable of producing explosive dynamics, lifelike timbres and life-sized holographic images. The minimum recommended power is 8 watts and benign mainly resistive 6-ohm impedance ensures amplifiers won't struggle. The driver compliment is a 23cm tall air-motion transformer working in a proprietary horn; a 12" midrange with a lightweight paper cone; and an 18" woofer working in a bass-reflex arrangement tuned to 25Hz. Crossover points are at 200 and 2'500Hz, bandwidth is 25 to 20'000Hz."
