Five Channels for Immersive Surround Sound

The CS2300 II Home Theater Speaker System contains five total speakers: four 3-1/2-inch, two-way bookshelf speakers and one dual 3-1/2-inch, two-way center speaker. When paired with a surround-sound-enabled receiver, the speakers are capable of producing an expansive soundstage similar to what you would experience at a movie theater. Dialogue and sound effects are split up between the four bookshelf channels, producing the surround-sound effect. Meanwhile, the central channel handles dedicated dialogue tracks, adding further depth to the soundstage. The result is a dynamic, theatrical soundscape that truly immerses you in the movie.

The CS2300 II can also be paired with Boston's CS Sub10 II Down-Firing Subwoofer to create a complete home theater system that delivers across the entire frequency system.

Audio Technologies Deliver Stunning Performance

Each speaker in the CS2300 II is outfitted with Boston Acoustics' best audio technologies. The system incorporates Boston's Deep Channel Design: the polymer woofers are injected with graphite, allowing them to produce a more resonant bass sound without bottoming out. The Kortec tweeters feature a soft-dome design and have been treated with a stiffening agent to eliminate the high-frequency feedback that usually accompanies metal tweeters.

Together, the tweeters and woofers are able to reproduce frequencies ranging from 80 Hz to 25 KHz, ensuring faithful playback of your movie's audio track. In addition, the dynamic range is flawlessly balanced so that the front, rear, and center channels blend seamlessly together.

Smart Design Enhances Audio Experience

The CS2300 II also incorporates other smart audio-enhancing features. The speakers are equipped with five-way gold-plated binding posts, which ensure a secure and reliable wire connection. The gold plates also help preserve signal transfer, minimizing frequency losses and gaps. Additionally, the speakers feature MagnaGuard magnetic shielding, which helps prevent video interference when the speakers are placed close to your television screen.

Easy, Flexible Installation Options

The CS2300 II is designed for a quick and flexible installation. The speakers can be mounted on a wall or simply placed on a stand or on a shelf. Keyhole wall brackets are built into the speakers to ease wall-mounting. The speaker wires are extra pliable, allowing you to place the speakers wherever you choose.

Stylish Wooden Finish

The CS2300 II matches its exceptional audio quality with equally exceptional style. The speakers boast two finish options; each complements a variety of furniture styles. The speakers also feature a traditional box chassis, giving them a classic, balanced aesthetic.

The Goal of the Classic II Series

Boston's Classic II Series was designed to offer consumers an affordable solution without sacrificing sound quality. The series continues Boston's tradition of creating stylish, high-performance box speakers.

Boston Acoustics creates all of its speakers following the Play Smart approach to product design--sensible, useful, smart design features combined with contemporary styling. The Classic II series is no exception: each speaker in the series has been engineered using Boston's finest technologies to deliver outstanding performance.

The CS2300 II Home Theater Speaker System is backed by a five-year manufacturer's warranty.
