Released March, 2008
The Pros:Bass end is very tight, not at all muddy. Titanium-laminate tweeter offers some of the best high-ends available in this price range. Medium-Density Fiberboard construction is solid and durable.
The Cons:Quite large for shelf speakers (15 1/4" x 8 3/4" x 13"). Their weight (19.6lbs) makes mounting these on stands quite difficult. Metal tweeters and high frequency response make these speakers sound a tad too "bright" for some tastes.
The JBL ES30 is a 3-way bookshelf loudspeaker that sports a 6” proprietary PolyPlas shielded low-frequency subwoofer and one ¾” titanium-laminate tweeter mounted in Elliptical Oblate Spheriodal waveguides for improved high-frequency dispersion anywhere in the room.

The second bookshelf speaker in the JBL ES series, the ES30 is in fact an upgrade from the ES20. It sports a larger subwoofer (6” versus 5” and offers a wider frequency response (50Hz-40kHz versus 65Hz-40kHz), an improved sensitivity (88dB versus 86dB), and a superior crossover frequency (3300Hz versus 3000Hz). The JBL ES30, however, maintains the ES20’s ultra-high frequency (up to 40kHz), not to mention its super-elegant cabinet design with a slender profile built from a wood-like and textured high-quality vinyl. The JBL ES30 also comes equipped with a bass-reflex port for extended bass responses, EOS waveguides that evenly disperse high frequencies to deliver a more accurate imaging, a straight-line signal path crossover network that preserves clarity and detail, and cellulose-fiber cones reinforced with a Polmer coating for a “uniform pistonic motion” and results in no internal resonance and a more precise base. Available in either black, bleech, or cherry, the JBL ES30 is priced at $299.99, a $100 increase from the inferior 5” JBL ES20.

Wood grain and black finish options are a nice touch, make it easier to mesh in with a room's decor.
