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 L100T loudspeakers

JBL Speakers for Accurate Sound Reproduction

The accurate reproduction of sound requires different physical demands upon a loudspeaker. The deepest bass frequencies, especially at high volume levels, require the speaker cone to travel quite a distance in order to move the necessary amount of air. Conversely, high frequencies require a diaphragm that can move much more rapidly, over shorter distances. The choice of capacitors, resistors, inductors and the circuitry in speaker design is of critical importance to the  resulting sound.

In the "L" series, the same speakers that are auditioned by engineers and producers while recording - the speakers by which the quality of the sound is judged by the professionals throughout the recording process - are here for the home environment. The "L" series from JBL.

 

JBL's top-of-the-line three-way , floor standing system reproduces sound equivalent to first generation sources - compact discs, master tapes and high performance pressings, possessing a sensitivity of 91 dB at 1 Watt/1 meter, a continuous power rating of 200 Watts, and dynamic power rating of 800 Watts (peak IEC shaped noise). The L100T integrates a pure titanium high frequency trasducer (o35Ti), laminated high polymer cone mid-frequency trasducer, a 12-inch Aquaplas low frequency trasducer and High Spatial Identification Dividing Network to truly recreate the professional sound in the home.

 


Titanium High Frequency Transducers for The Clearest Sound Available

Polypropylene to provide The Smoothest Response

Aquaplas for Low Frequencies - a proven material with the pros

JBL's Unique SFG (Symmetrical Field Geometry) - to produce deep, powerful, and clear bass.

"L" Series with High Spatial Identification Dividing Networks

Integrity in Construction and Quality Internal / External Connections

Cabinetry - Aesthetic As Well As Acoustic Excellence

The "L" Series - bringing Professional Sound all the way home.
