Product Description

Amazon.com Product Description

The JBL S312 is a 3-way, 12-inch floor-standing single loudspeaker with medium-density fiberboard (MDF) enclosure and Elliptical Oblate Spheroidal (EOS) wave guide. Technical specifications include a balanced and nearly full-range (35 to 20,000 Hz) frequency response, 8 ohms nominal impedance, 92 dB sensitivity, and 250-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 12-inch PolyPlas (polymer-coated cellulose fiber) cone woofer is built on a cast aluminum frame, which reduces distortion and increases power-handling capability.

Shielded components allow distortion-free placement near video monitors. A high-temperature, oversized Kapton voice coil and HeatScape motor structure allow these speakers to play all types of movies and music. A low-diffraction IsoPower baffle directs the sound power into the room, reducing any distortion caused by cabinet vibration. The computer-designed enclosure requires no bracing. The FreeFlow flared port increases bass response without adding unwanted port noise. As is true with all JBL Studio Series loudspeakers, the JBL S312 speakers are 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.

5.0 out of 5 stars Loud & Clean, April 1, 2002

This review is from: JBL S312 3-way Floorstanding Speaker (Pair of Speakers, Black Ash) (Electronics)

If you love music loud and clean, you need to audition these. I have listened to many speakers in my time and, in my opinion, you would be hardpressed to find a better performer for the money. I listen to a variety of types of music and I'm never disappointed in these speakers. Played through a 50wpc tube amp and coupled with a PSW 12 sub, the sound is so good that I hear things on my CD's I haven't heard before. And my old speakers are on the famous Stereophile Recommended Components list. I did notice that a bookshelf speaker in this Studio Series is already recommended by Stereophile as well, so that should be an indication that this is a serious speaker. Do not confuse this series with some others in the JBL line. The Studio Series is for real.

5.0 out of 5 stars JBL is back, December 29, 2000

This review is from: JBL S312 3-way Floorstanding Speaker (Pair of Speakers, Black Ash) (Electronics)

This is JBL's first offering worth purchasing since my old L100's. Buy a pair ... and put them up against anything in the .... You also get plenty of lows without purchasing a sub. They really perform after about 40 hours of break in. Reverse one of the leads, face the pair together, throw a blanket over them and give them a couple to three days.

These speakers are perfect, great looks, great sound,they are heavy though(70lbs), but what can you expect. They are worth every cent, they can play very loud while staying clear. They are beautiful.
