JBL 4307
10” (250mm) 3-way Control Monitor
The JBL® 4307, a home version of the monitor loudspeakers favored by recording studios, is compact yet powerful. This full-range, three-way speaker is small – just 21-1/2 inches (545 millimeters) high, 12-7/8 inches (328 millimeters) wide and 11-3/4 inches (300 millimeters) deep, and weighing just 36.8 pounds (16.7 kilograms) – but it re-creates music with the power, dynamics and accuracy that the JBL brand has delivered to audio virtuosos for over 50 years.
The system’s 1-1/2-inch (38-millimeter) tweeter features a tangential ring diaphragm mounted on a cast-aluminum horn for reproduction of accurate high frequencies up to 45kHz. A 5-inch (125-millimeter), polymer-coated, pure-pulp midrange speaker delivers dynamic performance in reproducing the human voice, even at high playback volumes. And a pure-pulp, 10-inch (250-millimeter) cone woofer offers natural-sounding, undistorted low tones.
Built-in level 1.5kHz and 6.5kHz attenuators let you to adjust the midrange and high-frequency performance to match your personal tastes. The recommended amplifier power is 150 watts, with a resultant frequency response of 45Hz – 45kHz (–6 decibels) and sensitivity (at 2.83 volts / 1 meter) of 91 decibels. And with a walnut-lacquer finish and blue grille, the 4307 looks as great as it sounds.
