Product Description

Amazon.com Product 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.

5.0 out of 5 stars Superb sounding speaker., September 22, 2002

This review is from: JBL S312 II 3-Way Floorstanding Speaker with 12" Woofer (Black Maple) (Electronics)

Many people, unfortunately, make the mistake -- often encouraged by a sales person -- of spending more money for electronic components than for speakers. But the most important components for determining the sound of an audio system are the speakers. And in the world of superb-sounding speakers JBL currently is the king. The S312 II is a great speaker with clean, sweet highs, natural-sounding midrange and clean, deep bass. There is no speaker at this price which sounds as good. If you feel that you must have a lower price, I recommend the JBL S310 II which drops the woofer size from 12" to 10" But either way, if you want great sound, get JBL speakers -- preferable the S series.

5.0 out of 5 stars Phenomenal Speakers for this price piont..., January 9, 2004

This review is from: JBL S312 II 3-Way Floorstanding Speaker with 12" Woofer (Black Maple) (Electronics)

The clarity and definition of the sound from these speakers is favorable over most anything at this price piont. You may even be able to find these for a little less if you search around online. The build and construction is top notch and each speakers comes in at around 50lbs. I do suggest that you purchase a separate sub in order to get that room shaking base you'd want in a quality home theater. The base is adequate for basic easy listening but doesn't catch the awe-inspiring "thump" that you'd want in some of your favorite action movie soundtracks. But pair these up with an effective sub and you're in for pure audio enjoyment. If you're looking to eliminate the sub option, you might want to look at getting the S412 with a 200-watt powered woofer section.

These are by far the best speakers for the money. I paid $450 for the pair delivered and they sound incredible. I have the all JBL Studio series speakers running through an Onkyo 701 home theater receiver -- what a combinaton. They sound great for both movies and music! I highly recommend these speakers.
