Boston's compact RS 230 bookshelf speaker fits just about anywhere. Place a pair on a shelf or tabletop, and team them up with a matching subwoofer and for crisp, full stereo sound. Or mount up to seven of these speakers around your room using their keyhole slots, for home theater sound that immerses you in the action on your TV screen.

Smart tweeter technology for accurate high-frequency detail
Boston's new 1" Extended Wide Bandwidth tweeter lets this speaker really sing with silky, clear highs. Its unusual, dimpled design stabilizes the linear motion of the tweeter for significantly lower distortion, while improving dispersion, power handling, and clarity.

Multi-composite woofers, plus advanced cabinet design
The RS 230 also features a 3-1/2" woofer and an acoustically tuned port. This high-tech multi-composite woofer produces smooth, detailed midrange and solid midbass with minimal distortion. The smooth front baffle sports a shallow grille with magnetic attachments, a design that virtually eliminates diffraction, for a spacious soundstage and accurate imaging.

Why choose bookshelf speakers?

Bookshelf speakers may be small in size, but they can deliver surprisingly big sound. Some ultra-compact models even fit on a desktop. Most are right at home in tight spaces like shelves, so they're usually good choices for your home theater's rear channels. For the best performance, try placing bookshelf speakers on solid speaker stands to help the sound really "open up." If you want full bass impact, add a powered subwoofer and enjoy punchy sound that's as deeply satisfying as that of floor-standing speakers.

I purchased these speakers with the rs223 for a center and they fill the room with crystal
clear sound by themselves but if you want to feel the music and or movie they must be
paired with a good sub. but what can you expect from a speaker this tinny

Driver Technology

Tightly Spaced Driver Placement: The Boston Acoustic RS 230 bookshelf loudspeaker utilizes tightly spaced driver placement, to allow the speaker to deliver near-point-source sonic coherence, wide dispersion, and accurate imaging.

Smart Tweeter Technology: The Boston Acoustic RS 230 bookshelf loudspeaker's 1.0" EWB (Extended Wide Bandwidth) tweeter features special central diaphragm termination (creating a dimple) and a rear-venting chamber to provide stabilized linear motion, lower distortion, improved dispersion, higher power handling, and increased clarity.

Multi-Composite Woofer Cone: The Boston Acoustic RS 230 bookshelf loudspeaker incorporates a 3.5" Fiber Ceramic Copolymer Material (FCCM) Woofer cone made from a composite of fiber and ceramic materials impregnated in a proprietary copolymer. By combining these multi-composite cones with Boston's Deep Channel Design (DCD), the woofer produces a smooth response over the entire operating range. Deep Channel Design (DCD) provides more bass from less amplifier power.

Enclosure Design

Bass Reflex Enclosure: The Boston Acoustic RS 230 bookshelf loudspeaker features a bass-reflex cabinet with a rear-firing port for added efficiency and bass response. The enclosure features an elegant, scratch resistant high-gloss black lacquer finish.

Super Linear Plane (SLP) Baffle: The Boston Acoustic RS 230 bookshelf speaker features a Super Linear Plane (SLP) Baffle which offers a smooth surface baffle with invisible hardware. The Super Linear Plane Baffle has the ability to nearly eliminate acoustic diffraction.

Magnetic Grille: The Boston Acoustic RS 230 uses a super-shallow grille with an invisible magnetic attachment to create an almost entirely seamless alignment with the baffle plane to significantly reduce sonic barriers. The magnetic super-shallow grille minimizes acoustical interference for an improved soundstage.


Binding Posts: The Boston Acoustic RS 230 is equipped with gold-plated binding posts on the back of the speaker. The binding posts will accept bare-wire, pin-connectors, and single banana-connectors.

Mounting Options

Mounting: The Boston Acoustic RS 230 can sit comfortably on a shelf, stand, or tabletop using the supplied rubber feet. The RS 230 also features a rear-mounted keyhole slot, so you can easily wall-mount the speaker using a single dry-wall screw (not supplied). In addition, the Boston Acoustic bookshelf loudspeaker features a rear-mounted 1/4"-20 threaded insert for using an optional articulating wall-mount bracket (sold separately).

Video Shielded: The Boston Acoustic RS 230 offers MagnaGuard video shielding so you can safely place the speaker next to your television without distortion or interference.
