Features

2-Way Driver Design: The Stage 240B bookshelf loudspeaker employs a 2-way driver design that features 1" anodized aluminum dome tweeter with JBL's High-Definition Imaging (HDI) waveguide, plus a 4.5" Polycellulose ribbed cone woofer with rubber surround for lngendary JBL sound.

• 1" Anodized Aluminum Tweeter with HDI Waveguide: The Stage 240B features a 1" anodized aluminum dome tweeter that is coupled to JBL's High-Definition Imaging (HDI) waveguide for a smooth and natural high frequency repose. Through intense research of previous waveguide designs, JBL developed a new complex HDI waveguide geometry that improves directivity and reduces diffraction for better performance both on and off axis. The Stage 2 HDI waveguide is coupled to an anodized aluminum dome tweeter to enhance efficiency and dynamics. This new design offers a neutral frequency response both on and off axis.
• 4.5" Polycellulose Ribbed Cone Woofer: The JBL Stage 240B houses a single 4.5" Polycellulose ribbed cone woofer with rubber surround. This pure pulp cone has a proprietary mix of other materials added to it along with a ribbed design to improve its rigidity, so it can produce produce deep, accurate, room filling bass.

Precision Crossover Network: Premium components are used to construct the 2-way crossover in the JBL Stage 240B speaker. The high frequency section features air core inductors and mylar capacitors that reduce distortion and improve sonic performance, while the low frequency section includes laminate core inductors and electrolytic capacitors. These premium materials can handle more power and transmit energy faster elevating system performance.

Bass Reflex MDF Cabinet: The JBL Stage 240B bookshelf loudspeaker features a bass reflex (ported) MDF cabinet with wood-grain vinyl finish. The rear-firing flared port features a new flared design to reduce the velocity of the air when exiting the speaker cabinet, eliminating any "chuffing" or coloration of output. Foam plugs are included to close off the bass port to reduce bass output if its too boomy when positioned next to a corner or wall. The foam plugs should also be used when wall-mounting the speaker to avoid unwanted distortion of sound.

Magnetic Attached Grille: The included cloth grille attaches magnetically to the front baffle of the JBL Stage 240B bookshelf loudspeaker.

5-Way Binding Post Terminals: The JBL Stage 240B is outfitted with a set of 5-way binding post terminals that will accept barre wire (up to 12AWG), pin-connectors, spade-lugs, or banana plugs (single or dual).

Mounting & Placement Options: The JBL Stage 240B bookshelf speaker can simply be mounted on a stand, shelf, or tabletop. Rubber feet are provided to provide a non-slip surface. The rubber feet add approximately 0.125" to the overall height of speaker. The Stage 240B can also be wall-mounted using the included bracket and hardware, or using an optional wall-mount bracket in combination with the speaker's rear-mounted 1/4"-20 threaded insert. The Stage 240B can be used in stereo music applications, or as front and rear speakers in a home theater setup.

• Stereo or Front Channels: For the best results, place a pair of JBL Stage 240B speakers 6' to 10' apart and angle the speakers toward the main listening position for improved stereo imaging. The speakers should form and equilateral triangle with the main listening position. The speakers will produce the most accurate soundstage when the angle between the main listening position and the speakers is between 40 and 60 degrees.
• Surround Channels: When using the Stage 240B as surround speakers, mount them on the side walls slightly behind the main listening position, facing each other. When using Stage 240B as surround back speakers, mount them on the rear wall directly behind the main listening position, facing forward. Ideally, the Stage 240B should be mounted 5' to 6' above the floor when used as a surround speaker.

Stage 2 Series: The Stage 2 Series from JBL delivers exceptional audio performance for today's music and movie enthusiasts. The Stage 2 Series consists of two floorstanding loudspeakers (280F / 260F), two bookshelf loudspeakers (250B / 240B), center-channel speaker (245C), and a multi-purpose height/surround speaker (240H), plus two powered subwoofers (220P / 200P) - all sold separately.
