INTRODUCTION
Congratulations on choosing JBL J Series Loudspeakers. Their highly accurate, uncolored and balanced sound character will greatly increase your enjoyment of recorded music and movies. JBL speakers are built with careful attention to detail, using only the highest quality materials. They will provide many years of excellent performance. The J Series is the result of combining traditional JBL Signature Sound performance values with elegant contemporary appearance. Maximum Cone Surface Area: The J Series transducers have been designed to maximize the cone surface area, a technology that allows for shorter excursion of the driver without sacrificing critical air movement. Maximum Efficiency: Larger air movement coupled with shorter coil movement allows the J transducers to be very efficient. See specifications. Maximum Transducer Control: Reduces distortion by tightening the control of driver excursion and increasing driver linearity. Smooth, Accurate, Extended Response: The J Series transducers, computer-optimized dividing networks, and bass reflex cabinets combine to give clear, crisp, accurate, JBL Signature Sound.

between them, at the listening position, is between 40 and 60 degrees (see Fig. 1). For example, if your listening position is 8 to 12 feet (2.5m to 4m) from each speaker, the two systems should be about 8 feet (2.5m) apart. Placing the loudspeakers in corners or against a wall will result in the strongest (not necessarily the most accurate) bass. Except for the J50, all J Series speakers have their ports in the front so you can place the rear of the speaker up against a wall. In the case of the J50, do not place the speaker closer than 3 inches (75mm) to the wall behind it if possible. For the best stereo imaging, we recommend that the systems be placed so that the high frequency transducers are positioned approximately at ear level of a seated listener. Every room is different and there are different tastes, so don�t hesitate to experiment on your own.

PLACEMENT
Bookshelf Models: For the best stereo reproduction, the two loudspeaker systems should be an equal distance from your listening position and separated so that the angle

Tower Models: The Tower models cabinet height and driver placement allow for speaker placement directly on the floor. For the best stereo reproduction, the two loudspeaker systems should be an equal distance from your listening position and separated so that the angle between
