JBL Club 4020 4" 2-way Speakers

This Club Series speaker's low profile allows it to fit in more vehicles.

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.

A match for any system

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.

Grilles are not included; the factory grilles should be suitable for most applications.

Product Research

Features

Plus One+ Woofer Cones: Each speaker uses a cone larger than other speakers of the same size. This is accomplished by using a unique basket design and hi-roll surround. The Plus One+ design offers greater bass output and an increase in efficiency.

Tweeter: Each speaker has a PEI (Poly-Ether-Imide) balanced dome tweeter. PEI is a polymer film that produces a wide soundstage for superior imaging.

High-Output Design: The 3Ω voice coil design compensates for the high in-line resistance of small gauge factory wiring, extracting more power from factory (or aftermarket) receivers. This results in clearer, richer sound for the listener.
