JBL speakers 500 watt four-way dual 9" floor-standing

Built for genuine entertainment enthusiasts, the L890 has a Polyplas™ woofer and FreeFlow™ port technology for extended, floor-rattling bass with low distortion. Kapton® voice coils and a HeatScape™ motor give you dynamic power handling. The Elliptical Oblate Spheroidal™ (EOS) Waveguide disperses sound, so pick any seat. It’s the best in the house.

Dual 8” PolyPlas™ cones for big bass response

Stiffer cones deliver more uniform pistonic motion for deeper, tighter bass and improved midranges. PolyPlas™ gives maximum impact JBL® audio. You’ll experience serious, feel-it-in-your-bones bass and true sound that does justice to the artist’s original performance.

JBL® HeatScape™ delivers great power handling

The HeatScape™ motor structure envelops the voice coil with a large ceramic magnet and steel frame that protects the voice coil by dissipating heat. This increases power handling and gives you extremely low levels of harmonic distortion.


Detailed high frequency sound reproduction

A thin, but rigid, 1” pure titanium-laminate dome tweeter delivers accurate high frequency response, even when the volume is cranked up. A Mylar® dome makes way for open, smooth spacious sound, and a seamless transition between the middle and high frequencies.

Sit-anywhere EOS™ Waveguide sound

Elliptical Oblate Spheroidal™ (EOS) Waveguides, originally developed for JBL® Pro LSR studio monitors, disperse clean, high frequency sound more precisely across a wider listening area. There’s no “sweet spot.” Sit wherever you want.

Proprietary SSP™ reduces noise and signal lose

By taking the shortest possible route from the input terminals to the transducers – simplifying and shortening the path – this proprietary crossover design means you hear everything your TV and music source can dish out

FreeFlow™ port technology extends bass response

Dual front-facing FreeFlow™ bass ports are acoustically matched to the woofer and move the air from the cabinet into the room. You get extended bass response with the lowest amount of distortion, adding power to your music and excitement to your movie soundtracks.

Accurate frequency response

From 28Hz to 40kHz, nothing is over- or underemphasized. You get a true, full sound range from deep bass tones to ultra-high frequencies.






Excellent audio output

With 115W of continuous power handling and 500W peak, the JBL® L890 has robust, muscular delivery. It uses technology derived directly from JBL® Professional studio monitors and gives your home theater audio the unparalleled spaciousness and definition it demands.
