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 L-222 (1980)

The JBL L222 loudspeakers systems offers extended frequency response, great dynamic range, outstanding musical detail, and exceptionally good stereo imaging.

Innovative and advanced engineering gives the L222 its exciting sound. JBL engineers created a design that aligns the acoustic centers of the individual loudspeaker elements while retaining the ideal flat baffle panel. Thus, all frequencies maintain the same time relationship to each other as they had when they were recorded, giving music the "presence" and immediacy of a live performance.

The combination of a 355 mm (14 ") woofer and large passive rediator gives the L222 awesome, deep bass. The specific tuning of the passive rediator adds warmth and presence to the mid-bass region, producing a dramatic and powerful effect at high volumes and an exceptionally pleasing sound, retaining full musical detail, at low listening levels.

Bold Visual Style

A tall, slim wedge the enclosure is a product of the JBL tradition of fine craftsmanship and attention to detail, a tradition extending back to the origins of the audio industry.

The L222 appears almost two dimensional an exciting presence, yet not visually overpowering. Its columnar array places the transducers, as nearly as possible at ear level, where they perform to fullest advantage. At the same time, the amount of floor space required is minimal.

Made of extensively braced 19 mm (¾") compressed wood (acoustically superior to solid wood) the enclosure features a veneer of American black walnut, hand rubbed with an oil/wax preparation to a lustrus finish.

Power Capacity

JBL products are unique in combining high efficiency with high power capacity. The L222 produces sound at comfortable listening levels when driven by as little as 10 watts continuous sine wave, but for the best performance we recommend a more powerful amplifier. The L222 can be used with amplifiers rated up to 400 watts continuous sine wave per channel.
