Description :
Similar to Avangarde Uno in design, this version of the JBL Summit L300 uses the same JBL drivers(136A, LE85, 077) as in the boxed version. The JBL Summit L300 is the home entertainment version of the 4333 studio monitor, and also one of the most successful loudspeaker designs JBL has produced for the recording industry. The JBL Summit L300 are impeccably styled, superb cabinet construction, and absolutely phenomenal driver quality. The 3-way speaker with extremely high-end components include a massive 15" JBL 136A woofer with 4 inch edge wound voice coil and an optimized alnico motor structure for ultra low distortion. The JBL LE85 midrange features a 1.75 diameter edge wound aluminum voice coil and an alnico motor structure. It fires through a cast aluminum exponential horn and wide dispersion lens assembly. The JBL 077 tweeter features a very efficient ring radiator design with an aluminum diaphragm which has been shown to be one of the most effective ways to achieve flat, extended frequency response beyond 20 kHz. The design of the high frequency driver matches the directivity of midrange horn beautifully which leads to a near-perfect transition between them. The speaker runs passive without the use of electricity at its woofer unit. The cabinets are finished in oiled black walnut, with black grill covers and smoked glass tops.

The JBL Summit L300 are robust sounding speakers producing sweet and effortless high end extension with a tactile quality and high resolution, and the midrange is smooth and realistic. The 136A and 136H 15" woofer variants deliver very strong and accurate bass with minimal wattage. The authoritative bass performance of the classic woofer still rivals the best modern designs. The JBL Summit L300 are dynamic sounding and all-around speakers with any type of music, particularly great on rock and jazz. Whether in its working dress at the studio, or a decorous expression for the home, the acoustical performance is identical: engineered to provide the mighty reserves of sound power, broad bandwidth and undistorted response. The quintessential 3-way speaker system will blow the listener away with its carefully blended combination of graceful and intimate detail and raw, chest pounding power.
