JBL Synthesis L100 Classic 3-Way Bookshelf Loudspeaker Overview

JBL’s classic L100 bookshelf speakers sported sculpted foam grilles in neon-bright colors – and could they ever rock out. (Audio aficionados should still recognize the speaker as the one featured in Maxell’s iconic “blown-away” ads.) As bold and bright in acoustics as appearance, they were in-your-face loud and clear, with the kind of sound that sent college kids to the moon – Keith Moon, most likely. JBL Synthesis, being as nostalgic as the rest of us, is bringing back the L100 Classic, updated for a new generation of music fans. In true retro style – including the Quadrex foam grille in choice of orange, blue or black – the L100 Classic is a three-way system with a big 12-inch white (!) woofer, 5-inch polymer-coated pulp midrange and 1-inch titanium dome tweeter with soft surround. The bass pumps prodigiously through the front port, and the highs go wide via the tweeter’s geometric waveguide. Efficient enough to be driven by a 25-watt amp and sturdy enough to handle 200, the new L100 again lets you tune mids and highs to your taste with front-panel knobs. The next best thing to jumping into a DeLorean and firing up the flux capacitor, the JBL L100 Classic is ready to rock you back to the future. Read our take on the new JBL L100s here.

Updated sound

Technology has advanced since the heyday of the originals in the ‘70s, so JBL has freshened the engineering in the three-way L100 Classics. The new 1-inch dome tweeter has a titanium diaphragm – unheard of back in the day – and throws the highs wide through a geometric waveguide. The 5-inch midrange is polymer-coated pulp, and the 12-inch woofer – sizable for a “bookshelf” speaker – is pure white. And, like the original, the enclosure design is bass-reflex, which means a port in front augments the low end for extra oomph.

Twist and shout

Retained from the original are the two front-panel controls so you can turn up, or down, the midrange and highs to suit your tastes – and, indeed, your hearing acuity might well be different these days, after all those decades of heavy metal head banging. Just saying.

Original style

The woofer, as in the original, is bright white, and the front baffle is matte black. So for extra drama, you could always remove the foam grille and show off your cones to friends. But the Quadrex foam grilles speak loudly, even when the speakers are silent. Available in your choice of burnt orange, blue or black, the sculpted shape seems to reach out to the listener and say, “Crank me up. Please.”

Finish it off

Even though the L100s are categorized as “bookshelf speakers,” you might rightly conclude that at nearly 120 pounds a pair, they seem a bit weighty for much modern shelving. That’s why JBL is also offering accessory floor stands, angling the speakers up to best sonic effect. But for the full retro feel, might we recommend you instead procure some cinder blocks and plywood planks for a sturdily stacked, and wholly appropriate, setup.
