JBL design. These speakers continue the longstanding tradition of precise studio monitor sound for which JBL is famous. You will enjoy the benefits of a 2' high- frequency compression driver, cast frame low-frequency transducers with vented pole pieces, and JBL’s proprietary Symmetrical Field Geometry. 4344MkII power handling. The utilizes a 2' compression driver with an Aquaplas-coated titanium dome. JBL has long chosen titanium as the material for its highest-quality high-frequency transducers and the 4344MkII is no exception.
Titanium possesses the essential requirements for a high-frequency transducer. First, titanium is extremely light, yet rigid.

For example, if the speakers are 8' apart, your listening position should be 8'–12' from each speaker. To widen the area in Position Front View which the best stereo image will be perceived, turn the speaker to face the primary listening position (Figure 2). Connecting the systems in this manner ensures that they will operate in phase; that is, they will work together rather than in opposition.
Connecting the speaker system out of phase will not cause damage but will adversely affect the speaker’s sound. Bi-Wiring 4344MkII’s outer connection panel and internal dividing network are designed so that separate sets of speaker cable can be attached to the low-frequency transducer and midrange/high-frequency transducer portions of the dividing network.
This is called bi-wiring. Bi-wiring can provide several sonic advantages and considerably more flexibility in power amplifier selection. As with conventional one-amplifier connections, make sure that all speaker cables are the same length. 4344MkII must be removed before bi-wiring. Loudspeakers in any of the.

It is necessary to use a high-quality active crossover module. Since each amplifier only drives a limited frequency range, this method allows the user to select amplifiers with the desired sonic character for low and high frequencies. The battery should be replaced approximately every three years. Consult your JBL dealer for specific recommendations.
If a problem occurs, make sure that all connections are properly made and clean.
