Jbl Stage 2 L240B White 2-way, 4.5″ Woofer, 1″ Aluminum Tweeter Bookshelf/surround Loudspeaker (white)

JBL Stage 240B Bookshelf Speakers (Pair) – White

This listing is the white finish variant of the JBL Stage 240B, the smallest bookshelf loudspeaker in the Stage 2 series. Everything under the finish is the standard 240B: a two-way design with a 4.5-inch polycellulose ribbed cone woofer and a 1-inch anodised aluminium dome tweeter in JBL’s next-generation HDI waveguide, in a compact bass-reflex cabinet. The white finish suits lighter interiors — pale walls, Scandinavian-style rooms, white media units — where a dark cabinet would stand out. The pair works as the main speakers of a compact stereo system, as a desktop pair, or as surround speakers in a Stage 2 home theatre.

• Wall brackets and mounting screws included in the box

Drivers and waveguide

The woofer’s polycellulose cone is a pulp-based material with added ingredients for rigidity, and its ribbed profile stiffens the cone further, helping it stay controlled through the midrange where voices and most instruments live. The tweeter is an anodised aluminium dome, a material JBL uses across the Stage 2 range for its combination of extension and low distortion. It fires through the patented HDI (High-Definition Imaging) waveguide, whose geometry — derived from JBL’s professional studio monitors — controls how high frequencies spread into the room. In practice that means a stable stereo image and consistent tonal balance across the seating area, not just in one narrow sweet spot, and dialogue that stays clear when the pair is used with a centre channel in a film system.

Performance and amplifier matching

JBL specifies a frequency response of 53 Hz to 25 kHz (plus or minus 6 dB), so the 240B pair covers the full music range with usable bass for its size, and a subwoofer can be added where deeper film effects are wanted. The crossover hands over between woofer and tweeter at 1.4 kHz. Sensitivity is 85 dB at 1 m with 2.83 V input and nominal impedance is 6 ohms; recommended amplifier power is 20 to 125 W, which covers most stereo amplifiers and AV receivers on the market. The rear-firing tuned port extends the low-frequency output from the compact cabinet, and the supplied foam plugs let you tame the bass if the speakers must sit close to a wall or in a corner.

Placement and the white finish

At 272 x 175 x 217 mm per speaker and 4.6 kg each, the 240B fits on shelves, sideboards, speaker stands and desktops. JBL includes wall brackets and mounting screws, so the pair can also be wall-mounted as surrounds, and anti-slip pads are supplied for shelf use. The white finish carries through the cabinet and trim, with grilles that attach magnetically for a clean front with no visible fixings. Because the finish is the only difference from the standard 240B, this pair mixes freely with other Stage 2 models — a Stage 245C centre, Stage 240H height speakers or a Stage subwoofer — where a system is built up over time.

Using the pair

As stereo mains, the 240B pair suits bedrooms, studies, small living rooms and near-field desktop setups, driven by a stereo amplifier or a receiver. In a home theatre it takes surround or surround-back duty, where its compact size and wall-mount option are practical advantages. These are passive speakers, so an amplifier or AV receiver is required; there is no built-in amplification or wireless input.

Clear, even coverage from a small cabinet, in a finish that disappears into light interiors — the white Stage 240B is the compact entry point to the Stage 2 range for rooms where looks matter as much as sound.
