JBL ES20BK Brings home the legendary JBL concert sound JBL ES20BK Delivers powerful, accurate audio performance Cleaner Sound with Higher Highs
With UHF drivers capable of 40kHz, ES Series speakers deliver high-end nuances you probably have never before experienced in recorded audio. The JBL ES Series uses cellulose-fiber cones reinforced with a polymer coating for uniform pistonic motion; this eliminates internal resonances, without increasing cone mass. That means tighter, more precise bass and midrange reproduction.
Better Imaging with Greater Accuracy
Originally developed for JBL Professional LSR studio monitors, proprietary waveguides evenly disperse high frequencies, delivering more precise imaging over a wider listening area. The extremely thin yet extremely rigid titanium laminate dome ensures accurate, undistorted high frequency response, even at realistic (meaning loud) listening levels.
Hear What You've Been Missing with the JBL ES Series
HDTV and the new HD-DVD and Blu-ray Disc formats deliver video images that are up to six times sharper than the best the 20th century had to offer. But these extraordinary new pictures are meant to be experienced with up to 7.1 channels of high-quality sound (which actually improves most people's perception of the picture itself). With the versatile new ES Series, high-definition video meets high-definition audio, and a new era of high-impact home entertainment comes of age.
For advanced, sit-anywhere 5.1- and 7.1- channel home theater systems, as well as good-old-fashioned, best-seat-in-the-house music systems, the ES Series offers a variety of bookshelf, wall-mount and floorstanding loudspeakers, and bring-down-the-house powered subwoofers. With innovative technologies derived directly from JBL Professional equipment, the ES Series delivers powerful, accurate audio performance in systems that are built to play loud and long. And with two finishes to choose from--black and cherry--they're designed to look good anywhere, with a style that equals their substance.

This review is from: JBL ES20BK 5.25-Inch 3-Way Bookshelf Speaker (Pair, Black) (Electronics)
wound up buying these for a space limited environment that didn't allow a 5.1 + setup. vocals and overall sound are excellent, there are no high points around 1khz as i had found in other speakers and there is no wom-wom mid bass which i also found in two other pairs i tried. overall this is a very balanced little speaker that would be something i would like to compare to an nht zero or klipsch b2. as others have stated, low end is lacking, however, i expected this. 5" drivers do not produce solid lows. the nice thing is that it rolls off smoothly and you do not get the wom-wom bass that many bookshelf speakers produce under power and lower bass notes.
