Studio L890

Following the rich legacy of our audio expertise in recording studios and movie theaters, JBL engineers have introduced the Studio L series. The L890 floorstanding speakers in this series can handle up to 500 watts of power, and are equipped with a pair of 8-inch (200mm) PolyPlas woofers and a FreeFlow port (capable of reproducing powerful bass). They also feature a 4-inch (100mm) midrange driver (capable of reproducing clear and accurate vocal performances), a 1-inch (25mm) titanium membrane high-frequency (HF) tweeter (capable of reproducing crystal-clear highs), and a 3/4-inch (19mm) ultra-high frequency (UHF) Mylar driver (capable of reproducing highs up to 40kHz). The high-frequency drivers are also paired with our exclusive proprietary Elliptical Oblate Spheroidal (EOS) waveguides, which can evenly disperse sound throughout the entire home theater.
