What is stereo?




There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

JBL L80T loudspeakers

Engineering Expertise

There are basically two ways for a company to build a loudspeaker system. The most common method is to buy the component parts from mass suppliers and assemble them, accepting the inevitable compromises which result from using off-the-shelf components.

JBL has a better way. For nearly forty years JBL has designed and built the entire system, form the initial computer calculations to the finished product. All variables are controlled so design goals never have to be compromised. Better engineering is the JBL approach to better sound. At JBL engineering takes many forms; Component design, testing of materials, manufacturing techniques and electronics. JBL always seeks new and better materials and subjects them to thorough examinations, including detailed vibrational analysis and magnetic measurements. A fully equipped tool and die shop is maintained to enable JBL to manufacture equipment with tolerances as close as two ten thousandths of an inch. JBL measures and analyses tone bursts, impulse response and phase response with the use of state-of-the-art. Time-display spectometry, Fourier analysis, and other advanced techniques. For the most accurate measurements conceivable, JBL employs a wide variety of specially calibrated condenser microphones, in addition to testing in their own anechoic chamber. Human ears still remain JBL's most sensitive measuring instrument. Every design is subjected to extensive critical listening by a panel which includes audiophiles, recording engineers and musicians, throughout a product's development.

 

The JBL L80T , a three-way floor standing system, yields unparalleled sound reproduction with its combination of a pure titanium high frequency transducer (O35Ti), laminated high polymer cone mid-frequency transducer, 10-inch Aquaplas low frequency transducer and High Spatial Identification Dividing Network. The L80T has a sensitivity of 90 dB a 1 Watt/1 meter, a continuous power rating of 150 Watts, and a  dynamic power rating of 600 Watts (peak IEC shaped noise). With its extended frequency response, ability to deliver original dynamic range and the re-creation of the full sound stage, the L80T sets the stage at home.
