A 15-inch woofer gives walnut veneer and sculpted foam a considerably larger canvas. The JBL L150 Classic becomes the flagship of the Classic Series, bringing its familiar 1970s styling to a three-way floorstanding design.

The cabinet pairs natural walnut veneer with a magnetically attached black Quadrex grille. Its front baffle slopes backward to aim the drivers toward the listening position, giving the enclosure a purposeful profile. At 36.8 inches tall, 18.5 inches wide, 21.2 inches deep, and 114.6 pounds per speaker, this is furniture-scale hi-fi with a substantial footprint.

Behind the grille, a 15-inch Pure Pulp Differential Drive woofer handles bass, joined by a 6.5-inch polymer-coated pulp midrange and a 28mm titanium dome tweeter. The tweeter sits in a waveguide with an acoustic lens; crossover points at 310 Hz and 1.8 kHz divide the work among the three drivers.

That familiar JBL loudspeaker vocabulary comes with useful adjustments. Stepped high- and low-frequency controls let the tonal balance change with the room. Rated bass extension reaches 33 Hz, or 30.5 Hz with the low-frequency control at +2 dB. These are specified limits, rather than listening impressions.

Dual gold-plated binding posts and separate high- and low-frequency crossover sections support bi-wiring or bi-amplification. Nominal impedance is 4 ohms, with recommended amplifier power of 25–250 watts RMS.

The L150 Classic is priced at $9,999 per pair.
