Offering exceptional sound at an affordable price, the Boston Acoustics CS 260 II Dual 6-1/2-Inch Floorstanding Two-Way Speaker is an ideal addition to your home theater or music system. This impressive floorstanding speaker was engineered with high-grade components to ensure stunning audio reproduction across a wide range of frequencies. A Kortec soft-dome tweeter offers crisp, high frequencies, while graphite-injected woofers deliver more bass response from less amplifier power.

Floorstanding Speaker Provides Immersive Sound

With the CS 260 II Floorstanding Speaker, you can enjoy your favorite media in richly detailed stereo sound. The speaker features a tower-style rectangular cabinet engineered for optimal acoustics. Pair it with other speakers from the Classic II series to create an expansive, cinematic soundstage.

Audio Technologies Deliver Stunning Performance

The CS 260 II is outfitted with Boston Acoustics' best audio technologies. The speaker incorporates Boston's Deep Channel Design: the polymer woofers are injected with graphite, allowing it to produce a more resonant bass sound without bottoming out. The 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 sound and music.

Smart Design Enhances Audio Experience

The CS 260 II also incorporates other smart audio-enhancing features. The speaker wires 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 speaker features MagnaGuard magnetic shielding, which helps prevent video interference when it is placed close to your screen.

Easy, Flexible Installation Options

The CS 260 II is designed for a quick and flexible installation. The speaker's wide base allows it to stand upright on the floor, and its slender cabinet takes up minimal space. The speaker's wires are extra pliable, allowing you to place it wherever you choose.

Stylish Wooden Finish

The CS 260 II matches its exceptional audio quality with equally exceptional style. The speaker boasts two finish options; each complements a variety of furniture styles. It also features a traditional box cabinet, giving it a classic, balanced aesthetic.

The Goal of the Classic II Series

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