JBL L88+ _Floorstanding speakers

Stand not include, but available with a fee.

Made in Los Angeles, California 🇺🇸

Early 1970s

Originally introduced as a more accessible version of the legendary JBL L100 Century, the L88+ hides a clever concept: it could be upgraded into a full L100 by adding the « M12 expander kit ». A smart move by JBL—offering flexibility and performance in one package.

The L88+ is a 2-way design, which actually brings a key advantage:

more coherence and smoother phase integration compared to typical 3-way systems.

The result is a punchy, direct, and highly musical sound.

Originally inspired by studio monitors, it delivers that West Coast signature: dynamic, lively, and forward.

Perfect for home listening with a true vintage studio vibe

Rare find today, especially in clean condition — a piece of JBL history that blends simplicity, upgrade potential, and iconic sound.
