Boston Acoustics CS23B Single 2-way black Classic series bookshelf speaker

It's right behind you . . .

Surround sound audio lets you experience all your favorite movies just as the characters do. If you're watching a spooky suspense movie, you hear the same creaky door opening behind you, the same rustle of leaves off screen. If action flicks are more to your liking, you hear bombs explode, shrapnel fly, and bullets zip by all around you. But in order to experience surround sound audio, you need a multi-channel speaker system. And to hear those eerie sounds or enveloping battlefield effects, you look to a system's rear-channel speakers. Combining a single 1.0" tweeter and single 3.5" woofer, the CS23 bookshelf speaker from Boston Acoustics serves up full, clear mid-range and high-frequency audio. Pair two of them up for powerful rear-channel audio or dynamic stereo listening.

Of drivers and ports

While a variety of design considerations are essential to producing a loudspeaker capable of delivering powerful yet clear audio, two stand out above the rest: a speaker's drivers and its cabinet. First, while the CS23 employs a 1.0" Kortec soft-dome tweeter to serve up crystalline high-frequency audio, it turns to a single 3.5" graphite-injected polymer woofer with Deep Channel Design technology to reproduce full bass and mid-range audio. Second, enhancing the reproduction of controlled, efficient bass audio, the CS23 sports a bass-reflex cabinet design. By freeing the movement of air behind the speaker's drivers, the acoustically tuned bass-reflex port not only allows for greater speaker efficiency but also achieves improved bass extension and performance.

MagnaGuard

All of the components in your home theater system use electricity. They use it for power and for audio and video signal transmission. Accordingly, they all emit some amount of electromagnetic radiation. Because speakers operate using large magnets and require large amounts of power to reproduce sound, their output of electromagnetic energy can potentially interfere with the signals being used by other components. Ensuring seamless integration in to your home A/V system, the folks at Boston Acoustics have designed the CS23 with MagnaGuard magnetic shielding, protecting other A/V components from electromagnetic interference.

Going for gold

Ensuring high-conductivity and low-corrosivity for high-performance, enduring audio reproduction, the Boston Acoustics CS23 speaker uses gold-plating on its five-way binding-post inputs.

The finishing touches — cables

Go one step further in your quest to reach the pinnacle of home audio. A high-performance floorstanding speaker like the CS23 can only help your home audio system reach its full potential if it is receiving a quality, high-integrity audio signal. Audio cables — chosen specifically for the needs of your system — deliver the ability to maximize your CS23's potential.
