Description

The L100 Classic is a three-way passive loudspeaker built around a 12-inch pure-pulp cone woofer in a bass-reflex cabinet with a front-firing tuned port. A 5.25-inch polymer-coated pure-pulp midrange driver and a 1-inch titanium dome tweeter behind an acoustic lens waveguide handle the upper range, with crossover points at 450 Hz and 3.5 kHz.

The styling follows the original 1970 L100: a satin walnut veneer cabinet and a Quadrex foam grille offered in black, burnt orange or dark blue. Separate attenuators for the mid and high frequencies let the listener trim the balance to the room.

The speaker connects to an external amplifier and is rated at 4 ohms with 90 dB sensitivity. It is sold singly, so a stereo setup needs two. JS-120 floor stands, sold separately, raise and tilt the cabinet.
