FEATURES

JBL equipped these Club 4020 4″ coaxial speakers with UV-resistant polypropylene woofers for stellar performance even under the stickiest (or chilliest) environmental conditions — after all, your car door isn’t the most forgiving place to reside.

The speaker’s patented Plus One™ woofer structure extends the surface area of the cone to give you a better midbass experience than other speakers this size. And a PEI balanced dome tweeter expands the high-frequency range, so you’ll hear musical details that you never heard from your old speakers.

The Club 4020’s low-impedance design safely draws more power from your car stereo to give your music extra punch, but you’ll get even better results feeding them power from an outboard amp.
