The Studio 220 bookshelf speaker was built to speak the languages of both legacy sound and forward-thinking technology. Tested relentlessly in the world’s most advanced sound research lab – our own – as well as pitted against competitors in real world comparative listening studies, we’ve engineered this loudspeaker to go above and beyond. We incorporated a front-firing 4” PolyPlas midrange speaker and a rear-firing Slipstream bass port that envelop listeners in tight, accurate bass. We always could have stopped there – but that’s not the JBL way. We took other design cues from our work building the world’s most legendary recording studios, giving our Studio 220 the kind of performance sound normally found at cinemas and multiplexes: a 1” CMMD® Lite high-frequency driver that ensures low-distortion, and a High Definition Imaging (HDI) waveguide design that offers pinpoint sound imaging and studio-grade balance. Then we topped it off with seductive features like gloss black paneling, soft rounded edges, and your choice of either Black or Espresso wood-grain finish.
