JBL Northridge E Series Bookshelf Loudspeakers (pair)

E30CH (Black/Cherry Wood)

You might notice the sleek design and warm cherry finish first, but only if the speakers are off. When the E30's are on, all you really notice is the sound. JBL uses pro-inspired technologies and proven, quality construction to bring their pro sound home.

Terrific Tweeter

These bookshelf speakers, like all Northridge E Series speakers, feature a titanium-laminate-dome tweeter, made from 75 percent titanium deposited on a lightweight substrate for high strength and rigidity along with excellent transient response, clarity, resolution and power-handling capability. Higher frequency sounds come through clean and clear, not distorted or "tinny". The tweeter operates in conjunction with JBL's redesigned Elliptical Oblate Spheroidal (EOS) waveguide, which directs sound toward the listening area and away from the side walls for a wider sound field, which means even greater imaging. The difference made by the improved EOS waveguide is most noticeable in even more realistic surround sound effects with your favorite movies, and music recorded in exciting new multi-channel formats. Hear what you've been missing with a set of E30CH speakers from JBL.

Wonderful Woofer

Lower quality speakers have trouble keeping up with high energy music and soundtracks, especially when there are big, sudden swings or changes (aka transients). An over worked speaker will "clip" sound it can't reproduce and if driven too hard, the cones will lose their shape causing distortion. As a result, you don't hear some of the sounds you should and what you do hear doesn't sound so good. The low frequency transducers in these E30CH Northridge Series E speakers utilize cones made from JBL's professionally proven PolyPlas polymer-coated-cellulose-fiber cone material, which combines the sonic neutrality of paper with the added rigidity of the PolyPlas treatment to dampen internal resonance and provide a smooth frequency response with faster transients. PolyPlas cones strike the perfect balance between having enough rigidity to hold their shape and enough flexibility to keep up with the music. That's why PolyPlas cones make such a huge difference. You hear all you should and it's all good. Strong, responsive PolyPlas transducers enable higher playback levels without distortion so even at maximum power, your E30CH speakers will sound great. Complementing the innovative cone technology, the low frequency driver also features JBL's HeatScape motor structure, which provides efficient heat dissipation for accurate driver performance even during high-volume playback. Keeping the drivers cool also helps prolong their life so you can get even more enjoyment from your JBL speakers.

All In One Great Package

The IsoPower baffle design used in Northridge series E speakers rigidly affixes the drivers to an extremely dense, non resonant baffle. This allows for maximum air movement and energy to be generated by the drivers, while minimizing energy loss. These E30CH bookshelf speakers feature high-strength, high-density enclosures that have been specially braced and damped for minimal internal vibration. These computer-designed, lock-mitred cabinets virtually eliminate distortion and their slim profile fits neatly into your decor.

Performance Packed Front to Back

Many modern speakers use what is known as a port to produce bigger sound from smaller speakers. But, just cutting an extra hole in the speaker does not a proper port make. JBL's FreeFlow Port Architecture utilizes a computer optimized flared aperture that is tuned to the woofer and cabinet for extended low-frequency response and improved efficiency. This lets the bass kick freely, without audible "port noise". Dual sets of sturdy gold plated, 5-way binding posts provide a secure connection and superior signal flow as well as enabling bi-amping or bi-wiring. From the baffles to the bass port, it all adds up to speakers that make the most of every watt you feed them, to provide a most satisfactory listening experience.

Straight-Line Signal Path

The drivers (transducers) in these E30CH bookshelf speakers are purpose-designed to match each other efficiently in frequency response so that little manipulation of the audio signal is required in the crossover network. This allows the use of a minimal number of high-quality electrical components in a shorter, simpler signal path. Because the signal undergoes very little processing in the crossover network, the clarity, detail and dynamics of the original content are preserved. The further you run, the less energy you have when you arrive at your destination. Audio signals are the same way. By simplifying and shortening the signal path, JBL engineers made sure that the signals traveling through your Northridge Series E speakers don't lose any of their power and realism along the way. The simplified design of JBL's signal path also produces more efficient and accurate separation of highs and lows. With the high and low frequencies isolated, the transducers in each E30CH speaker are able to do a superior job of reproducing all your audio. High to low and all points between, JBL speakers give you more of what you buy speakers for.

I recently purchased a pair of JBL 30CH speakers. I was very impressed by the quality of the speaker both in performance and craftmanship of the cabinet construction. This is a quality product. I recently remodeled our living room and used the 30CH pair and 2 JBL 80CH floor mounted speakers. It fills the room with beautiful sound. I purchased these for the intended use of listening to music. These speakers replaced a pair of Klipschhorns and I am very pleased with the change and the quality of sound from these JBL's. The service from Vann's is superior and I would not hesitate to purchase again from them.
