Legendary sound.
JBL® loudspeakers have been the overwhelming choice of music and movie professionals for more than 60 years, prized for their power, accuracy and dynamic range. Chances are, many of your favorite songs and movie soundtracks were mixed and mastered on JBL studio monitors, the industry benchmark for the playback of recorded sound. But you don’t have to be a professional to bring the signature JBL sound home. We build exceptional home entertainment systems that incorporate many of the same advanced technologies, materials and manufacturing techniques originally developed for our professional systems.

Most valuable player.
The Studio 120c system is an ideal choice for the center-channel speaker in a multichannel home theater system—delivering the exceptional clarity, realism and bass response that a great center speaker must. Voice-matched to other speakers in the Studio 1 Series (Studio 130, Studio 180 and Studio 190), the 120c renders the dialogue, music and effects of even the most challenging movie soundtracks with confidence and style. The rigid, heavily braced enclosure includes a rear-facing bass port for extended low-frequency response. The enclosure itself, available in a silver-tinted black or cherry vinyl finish, incorporates the distinctive JBL Weave design for a dynamic, one-of-a-kind look.

Advanced technologies and materials.
The Studio 120c system features dual 4-inch (100mm) low-frequency drivers with stiff, lightweight PolyPlas™ cones and rubber surrounds that dissipate heat and minimize compression and distortion, even at high listening levels. A CMMD® Lite tweeter dome with a proprietary Bi-Radial® waveguide eliminates unwanted resonances and distributes clear, distinct high-frequency sound over a wider listening area, greatly expanding your room’s "sweet spot." All drivers are magnetically shielded for placement near video monitors, a must for any speaker in a home theater system.

A cinematic experience at home.
Team the Studio 120c speaker with any combination of floorstanding or bookshelf systems in the Studio 1 Series to create the ideal multichannel home theater system for your listening space. You’ll enjoy the sharper, richer high-definition (HD) sound and precise 360-degree imaging that today’s most exciting movies demand.
