The JBL S310 is a 3-way, 10-inch floor-standing loudspeaker with medium-density fiberboard (MDF) enclosure and Elliptical Oblate Spheroidal (EOS) wave guide for wide, even sound dispersion. Technical specifications include a 40 to 20,000 Hz (+/- 3 dB) frequency response, 8 ohms nominal impedance, high 91 dB sensitivity, and 200-watt power handling. The 1-inch pure titanium tweeter and the 4-inch midrange transducer are mounted on a Linear Field Proximity (LFP) bezel that insures a seamless transition between the middle and high frequencies. The 10-inch PolyPlas (polymer-coated cellulose fiber) cone woofer is built on a cast-aluminum frame, which reduces distortion and increases power-handling capability.Magnetically shielded components allow distortion-free placement near video monitors. A high-temperature, oversized Kapton voice coil and HeatScape motor structure optimize this speaker for playing all types of movies and music. A low-diffraction IsoPower baffle directs the sound power into the room, reducing distortion caused by cabinet vibration. The computer-designed enclosure requires no bracing. The FreeFlow flared port increases bass response without adding unwanted port noise. JBL's S310 speaker is equipped with all-metal, five-way, gold-plated binding-post speaker terminals. This model comes in black ash and includes a two-year parts and labor warranty on the speaker enclosure and a five-year parts and labor warranty on the speaker driver and internal components.
