Description:
JBL's Studio Series S312 II is a three-way, full-range floorstanding loudspeaker capable of delivering clear, dynamic sound for both music and movies. It's sold as a single speaker. Buy two for stereo uses or pick up five or merely three for use in surround-sound applications--only three if you'll be using two other speakers to serve as the left/right front or surrounds. If your TV is on a high shelf or mounted on the wall, as would a flat-panel set, you can simply position the "center channel" speaker beneath it. Be aware that you don't need a television to enjoy multichannel surround sound: the SACD, DVD-Audio, and DTS-CD formats all make ample use of full-range center-channel speakers, providing you have the space and the inclination to set up speakers for 5- or 5.1-channel music listening. Use a powered subwoofer for the .1 low-frequency effects channel, or configure your surround receiver to fold the .1 signal into the audio feeding the other speakers--with the S312 II's 35 Hz bass rating, you'll have plenty of bass even without a subwoofer. The speaker's Elliptical Oblate Spheroidal (EOS) waveguide imbues sound with unparalleled spaciousness and definition. The pure-titanium tweeter and the midrange transducer are mounted on a Linear Field Proximity (LFP) bezel that ensures a seamless transition between the middle and high frequencies. The PolyPlas (polymer-coated cellulose fiber) cone woofer features traditional JBL engineering--the same technologies used in JBL's Professional equipment, which is found in stadiums, music halls, and movie theaters around the world. Shielded components allow speaker placement near video monitors. A high-temperature-capable, oversize Kapton voice coil and a HeatScape motor structure allow this speaker to play all types of movies and music with ease, no matter how dynamic the content. The unit's woofers are built on cast-aluminum frames, which reduce distortion and increase its power-handling ability. A low-diffraction IsoPower baffle directs the sound power into the room, reducing distortion from cabinet vibration. The speaker's lock-mitred, computer-designed enclosure requires no internal bracing. Its flared, FreeFlow port increases bass response without adding unwanted port noise (sometimes heard as "chuffing" when you really crank your tunes). JBL's custom-designed drivers allow the use of simple, Straight-Line Signal Path (SSP) crossover networks with high-quality electrical components that minimize processing that could degrade the signal. Finally, JBL has outfitted the S312 II with all-metal, gold-plated, five-way binding-post speaker terminals for secure and flexible hookups, from bare wire to banana-plug jacks. What's in the Box
