Our take on the Boston Acoustics A 25

by Kristen Schaub
Boston Acoustics

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.

Jazz up your sound system with Boston's A 25 bookshelf speaker. This little dynamo boasts clear, musical sound that'll add excitement to your movies and music. Use a pair in a stereo music system, or create a compact home theater system using a pair of A 25 speakers in both the front and rear of your room. Just add the A 225C center channel and either the ASW250 or ASW650 powered subwoofer to complete your system.

Advanced drivers deliver the Boston sound you love
The A 25 features Boston's 1" Kortec® soft dome tweeter for clear, crystalline highs. The advanced ceramic/glass fiber polymer 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 vertical and horizontal internal bracings to reduce unwanted resonance that can muddy the sound. Plus, as part of Boston's A Series of speakers, the A 25 features modern styling with a stunning high-gloss, scratch-resistant cabinet, a textured top panel for contrast, and a convenient magnetic grille.

Driver Technology

A-Series Bookshelf: The Boston Acoustics A-Series bookshelf loudspeaker (A 25) 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 5.25" woofer paired with a single 1.0" soft-dome tweeter.

1" Kortec Soft-Dome Tweeter: The Boston Acoustic A 25 features Boston's 1" Kortec soft-dome tweeter for crystalline high frequencies.

5.25" DCD Woofer: The Boston Acoustics A 25 bookshelf loudspeaker is fitted with a single 5.25" 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 25 delivers more bass response from less amplifier power.

Crossover Network: The crossover components in the A 25 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 25) 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 25 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 25) 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 25 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.

Note: The optional PinPoint heavy duty side-grip wall-mounting bracket (121AM40B, sold separately) can also be used to wall mount the speakers.

full, balanced sound.

Written By audioadventurer, westville,nj on Tuesday, June 17, 2014
Crutchfield Customer Review (What's this?)
 
I believe that a good stereo sound comes from the matching or the frequency responses of the speakers and amp. I combined the Boston A25 with the Yamaha S-A300 integrated amp, also from Crutchfield. The resulting sound was full and lively and well balanced. In short, a pleasure to experience.
Pros:
well balanced, full, lively, more bass than I would expect from a speaker of its size.
Cons:

Great Speakers

Written By Sam, Crofton, MD on Monday, December 30, 2013
Crutchfield Customer Review (What's this?)
 
I tried out Bose and smaller Klipsch speakers to replace my old Boston Acoustic book shelf speakers, but neither of them can touch these speakers. Great sound at a great price. The only reason I am not giving them a five star rating is that they aren't the top of the line models and can't meet the level of quality.

Attractive and effective.

Written By mingus, Illinois on Saturday, December 14, 2013
Crutchfield Customer Review (What's this?)
 
Good value for money typical of Boston Acoustic. These replaced some very old Bostons, they sound far crisper and look much better. As you might expect, they don't have a lot of base, but a small Polk woofer has taken care of that very effectively. These are used in the den for casual listening -- nothing too serious and I'm very pleased with these speakers.
Pros:
Decent sound for the money. Black gloss finish is modern and attractive. Build quality is excellent, construction is very solid.
Cons:
None

Exceptional Value

Written By Dumas, South Texas on Saturday, June 08, 2013
Crutchfield Customer Review (What's this?)
 
With a decent pair of stands this is the best sounding set of small speakers I've heard in ages.
Pros:
When placed 6"+ from the wall they sound like a much larger pair of speakers.

nice quality for the money

Written By AdamH, New York on Wednesday, December 19, 2012

I added these speakers to my living room, small enough to be inconspicuous yet large enough to produce nice sound quality. I will probably by another set for my camp.

Great Speakers

Written By Bart Audio Junkie, Mountgomery county Tn on Monday, November 26, 2012
Crutchfield Customer Review (What's this?)
 
I bought these as Surround speakers and have a set of TEIL CS2.4 as the main pair. Running it on an Onkyo AV receiver. These are great I read a lot of reviews and lab tests before making my purchase. If you look at the frequency response of bench testing at audiophile websites for these speakers you will find that they are very acurate and not colored. (also have the A26 speakers as B speakers see my review there they are very similar but more base). By colored the speakers do not have any inherently brite or dull areas. The cabinets are also very ridgid and do not have any vibration or distortion from the tuned port as the Reference POLK RTiA3 rated well at Crutchfield by purchasers but not as accurate and smooth as this speaker. Boston acoustics has done an excellent job. If you want deep rich base you may need a subwoofer with these but less so with the A26"s. They have excelllent stereo imaging and and are crisp clear and pleaseing to listen to for hours. I swapped them out with my THIELS and was impressed how they compared. Not as full. rich and accurate but amazing for the price.
Pros:
Excellent all round speaker if used with a subwoofer.
Cons:
None.
