Enjoy clean, clear sound in an ultra-compact design with the Boston Acoustics A 23 bookshelf speakers. A pair of these mighty mites makes a great choice for setting up a high-quality desktop or bedroom music system. Or, create an entire compact home theater setup using five A 23 speakers in both the front and rear of your room. Just add the ASW250 or ASW650 powered subwoofer to complete your system.

Advanced drivers deliver the Boston sound you love
The A 23 features Boston's 1" Kortec® soft dome tweeter for clear, crystalline highs. The advanced ceramic/glass fiber polymer mid/woofer uses Boston's Deep Channel Design® to deliver more bass response per watt of amplifier power. The crossovers in all A Series speaker models incorporate low-loss capacitors and low-distortion cores for the inductors. It means you'll hear every note in your music with minimum distortion.

Thoughtful cabinet design
This speaker's cabinet design also features internal bracing to reduce resonances that can muddy the sound. Plus, as part of Boston's A Series of speakers, the A 23 features modern styling with a stunning high-gloss, scratch-resistant cabinet, a textured top panel for contrast, and attractive cloth grilles attached with magnetic fasteners.

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.

Better than my old Boston speakers

Written By desper-otto, Texas on Sunday, July 05, 2015

Crutchfield Customer Review (What's this?)

I was hesitant to buy speakers I hadn't auditioned, but Crutchfield's liberal return policy convinced me to give it a try. I had been using a 20-year-old SubSat7 as my desktop music system, and figured maybe things had improved in the past couple of decades. Honestly, these made the old speakers sound downright harsh! I paired these with my Velodyne sub and the sound is amazing.

Pros: Vocals are up front, but smooth. The stereo imaging is great. I couldn't be happier.

Cons: The bass is a little wimpy, but what do you expect from a small bookshelf speaker? Add a decent sub and it'll sound glorious.

Clean and precise, sounds great. you need a subwoofer to add the bass but they sound great with one!

Super Sound

Crutchfield Customer Review (What's this?)

I've always been a "Boston Acoustics" fan and the same is true here. The sound for the size of the A23s is amazing. The highs are crisp and clear while the bass response is equally as good.

Pros: Great sound for the size!...Highly recommend these speakers.

Cons: The protective film, while glad it was applied was a little tough to get off. Other than that, no problems.

Looks and sounds great

Crutchfield Customer Review (What's this?)

We are very happy with our A23 speakers.

Very smooth and powerful speaker

Written By Daren, Brandywine, MD on Monday, July 16, 2012

Crutchfield Customer Review (What's this?)

A very underrated speaker. Full and balanced without any of the upper-end harshness that i found on speakers that retain wonderful reviews in the AV mags. Suggest tweaking up the bass to get a little more of the lows, but it is an excellent speaker for near-field listening.

Pros: Great balance, rich sound at moderate listening levels. More bass than you would expect from a 3.5" woofer. strong Definition at the top end w/o sounding skreetchy.

Cons: It could be a little more defined at lower volume levels, but it is worth the trade-off for the better aspects of the speaker.

Driver Technology

A-Series Bookshelf: The Boston Acoustics A-Series bookshelf loudspeaker (A 23) incorporates high-quality components that produce the legendary Boston Sound. The A-Series bookshelf loudspeaker is ideally suited for use in a high-quality multichannel home theater or stereo music system.

2-Way Speaker System: The Boston Acoustics A-Series bookshelf loudspeaker features a two-way design that employs a single 3.5" woofer paired with a single 1.0" soft-dome tweeter.

1" Kortec Soft-Dome Tweeter: The Boston Acoustic A 23 features Boston's 1" Kortec soft-dome tweeter for crystalline high frequencies.

3.5" DCD Woofer: The Boston Acoustics A 23 bookshelf loudspeaker is fitted with a single 3.5" ceramic/glass fiber polymer woofer with Deep Channel Design (DCD) that allows for higher speed, reduced distortion, and improved sensitivity. As a result the A 23 delivers more bass response from less amplifier power.

Crossover Network: The crossover components in the A 23 incorporate low-loss film capacitors and low-distortion laminated silicon steel cores for the inductors in all critical areas. The tweeter and woofer are crossed over at 2,400 Hz.

Enclosure Design

Bass Reflex Enclosure: The Boston Acoustics A-Series bookshelf loudspeaker (A 23) features a bass reflex enclosure with a rear-firing acoustically tuned port for improved low frequency response and efficiency.

Scratch Resistant, Resonance Free Cabinet: The Boston Acoustics A 23 bookshelf loudspeaker features a high-gloss, scratch-resistant cabinet with a textured top and magnetic grille for a modern styling that will match most any decor. Vertical and horizontal internal bracings reduce cabinet resonances for enhanced audio quality.

Connections

Binding Posts: Gold-plated binding posts provide hook-up flexibility and the purest signal transfer. The binding posts will accept bare wire (up to 12-gauge), pin connectors, spade connectors, and banana plugs (single only).

Note: The binding posts are spaced to far apart to accommodate dual banana plugs.

Color-Coded: The speaker's binding posts are color-coded (red/black) for easy identification between positive and negative.

Mounting Options

Rubber Feet: The Boston Acoustics A-Series bookshelf loudspeaker (A 23) includes four self-adhesive rubber feet for safe and secure placement on a table-top, shelf, or, stand, other AV furniture. The rubber feet add 0.125" of height to the bookshelf speaker.

Wall Mounting: The A 23 bookshelf loudspeaker is fitted with a single keyhole slot to wall mount the speaker to a wall stud (mounting screw not supplied). Two self-adhesive rubber bumpers are included to attach to the rear of the speaker to prevent marring of your wall.
