JBL E10

JBL E10 surround speaker. The speakers and covers are  in perfect condition and can be tested prior to purchase. Features The E10, a 2-way 4" bookshelf loudspeaker with high-impact molded enclosure, reproduces sound with unmatched clarity and power. The PolyPlas(polymer-coated cellulose fiber) cone woofer features traditional JBL engineering - the same technologies used in JBL's Professional equipment that can be found in stadiums, music halls and movie theaters around the world. Shielded components allow placement near video monitors. High-temperature, oversized Kapton voice coil and HeatScape motor structure allow these speakers to effortlessly play all types of movies and music. The FreeFlow flared port increases bass response without adding unwanted port noise. JBL's custom-designed drivers allow the use of simple, Straight-Line Signal Path (SSP) crossover networks with high-quality electrical components, minimizing processing that could degrade the signal. Titanium-Composite High Frequency Transducer Domes Light enough to accurately reproduce lighting-fast sounds like cymbal crashes, yet strong enough to eliminate distortion and ear fatigue in the critical high-midrange frequency band. Elliptical Oblate Spheroidal (EOS) Waveguides Enables speakers to evenly disperse high frequencies and create precise stereo imaging over a wide listening area - instead of in just a tiny "sweet spot" right in front of the speakers. PolyPlas Enhances the organic fiber structure of low-and midrange-frequency cones, without adding significant weight. The PolyPlas coating eliminates internal resonances and unifies pistonic motion. You hear tighter bass and improved midrange response. Heatscape Precision Motor Structure Protects low-frequency transducers from destructive thermal buildup, the number-one enemy of professional and home speaker systems. Heat is conducted away from the transducer's sensitive voice coil and dispersed. Freeflow Port Architecture Extends lo
