Compact, budget-friendly speakers

The Alpha B1s will show you what high-end sound is all about, but at a low-end price. Like every PSB speaker, they're designed to make sure you don't miss all the thrilling special effects and emotionally engaging sounds in your movies and music. You'll be amazed by their ability to produce clean, clear highs and mids that make your movies and music come to life. It's no wonder they're among PSB's best-selling speakers.

Excellence by design

PSB's engineers began by designing each Alpha speaker from scratch to ensure that they'll deliver the same level of performance typically found on speakers twice their price. The Alpha B1s use a 3/4" aluminum dome tweeter to deliver crisp, sparkling highs. The 5-1/4" woofers are made of metalized polypropylene, making them strong but lightweight. It means you'll hear excellent midrange detail and distinct bass without a trace of the listening fatigue that can happen with lesser speakers.

Build a complete Alpha system

Create a complete, budget-friendly Alpha home theater system using a combination of Alpha B1s in the front of your room, the C1 center channel, and either another pair of B1s or the LR1 satellite speakers in the back of your room. And don't forget to add a PSB powered subwoofer (or two) for room-thumping bass.

Good speakers for home office room

Mitchell Dewayne from Edmond, OK on 2/13/2019

Verified customer (What's this?)
Verified employee purchase (What's this?)

Quite pleased with these speakers for a modest home office. Mainly listen to classical music in this setting. Good highs and mid-ranges; lower bass handled by separate subwoofer in this installation. Have them on Sanus steel foundation 30 inch stands - perfect for my needs.

Pros: Accurate, high quality, attractive, priced well

Cons:

Lively and musical bookshelf speaker

Gary from Grand Forks, ND on 1/2/2019

Verified employee purchase (What's this?)

The PSB Alpha B1 is a classic bookshelf speaker with a deserved reputation as a great-sounding, quality-made product. They sound fantastic for the price, lively, musical, and smooth. You get the feeling these speakers are beckoning the listener to embark on an audiophile adventure.

Pros: Better sound than you'd expect. Super-quality construction.

Cons: Like any bookshelf, could benefit from a mini-sub for a really thumping experience. Otherwise, no serious cons at this price.

The speakers arrived in undamaged packaging, but one speaker grill was significantly dented. I can only assume that it was dented either before or during packing at the factory. I was able to repair the grill to near perfect condition, so I did not contact Crutchfield. The speakers are a good buy for the price.

Great bookshelf speaker with startling clarity

Ed from Albany, NY on 9/11/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

I have these in my home office powered by a Sonos Connect amp. I absolutely love their clarity and the amount of low end they output for a speaker of this size. In many ways, they outperform the speakers I have in my main listening room that cost twice as much. While I briefly considered pairing the Alpha B1's with a subwoofer to supplement low-end, I ended up deciding against it. Provided your room is not too large, these speakers provide ample bass output for music. I would also hate to do anything that might muddy their midrange clarity. One note: I was a little bit surprised by the Alpha B1's size when the box arrived. This is a true bookshelf speaker, not a desktop monitor. Plan ahead, and if you intend on placing these on stands, make sure they are substantial enough to support a speaker of the Alpha B1's size/weight. Otherwise, happy listening - I doubt you will be disappointed.

Pros: Ample low-end; fantastic clarity; well-priced.

Cons: Wish more finishes were available Stateside - I'd gladly pay $50 more for gloss white or piano black.

After looking around for a pair of bookshelf size speakers to replace two much larger floor standing speakers for the front left and right in my surround system, I settled on this pair.

Guest from Irmo, SC on 4/14/2017

Verified employee purchase (What's this?)

These speakers were a significant upgrade over the Boston Acoustics C26II that I had set up in my office. The soundstage seems a lot fuller and they aren't as bright at the Boston Speakers. It's hard to explain, but it seems like a fuller more spacious sound. I have been listening to a lot of older vinyl and really happy with my new setup. They just seem to reproduce great sound very effortlessly, not really sure how else to describe it. These are my first "audiophile" grade speakers, albeit budget ones at that. Very happy with the purchase and the guidance I received from Crutchfield about buying these as well. I have these paired with a sub in a 2.1 stereo setup in my office and it probably sounds better for stereo than my way more expensive HT setup...

Pros: Great overall sound in a small package. Nice highs without being harsh or bright, great mid bass and vocal reproduction.

Cons: None...

I agonized choosing a pair of speakers that would match my setup (NAD d3020 + NAD C516bee) as well as my small weird listening room. I listen to a lot of classical piano, cello, voices (Ella Fitzgerald and some opera) and dixie Jazz, I needed speakers that would deliver a full sound, well balanced base, exceptional at reproducing highs. I read all of the reviews (TAS, Stereophile and others. They were more confusing than anything else. I am no PhD in music or electronics. I am a regular guy who loves his music with a very limited budget. This does not mean that I am musically deaf, budget daft or in denial of what I need and want. I called Buddy my Friendly Crutchfield advisor and explained my situation. He recommended the PSB Alpha B1, on sale and meeting all of my requirements. A few days of playing them loud (not too loud as I have difficult neighbors and I am in heaven!! Just buy these little gems.

Mikey H. from Tulsa, OK on 8/9/2016

Verified employee purchase (What's this?)

These things are, in my opinion, the best value in loudspeaker on the market. At 300 clams a pair, they're an absolute steal. I have them paired with an Onkyo receiver, Musical Fidelity V-90 preamp, a Pro-Ject Debut Carbon with a Orto 2M Blue and CD player. I've never heard this particular setup sing as pretty as it does with these speakers. These are audiophile quality without the typical audiophile price.

Pros: Price Size Great mids and highs. Pair these with a decent sub and you'll cry.

Cons: Not a thing.

Can't beat the sound quality/price mix!

Rich G from New Market, MD on 6/11/2016

Verified customer (What's this?)
Verified employee purchase (What's this?)

Bought these as the 'mains' for a 2.1 A/V system house warming gift for my daughter. They sounded great right out of the box - clear, smooth highs, rich mid-range. Paired with a good 8 inch sub (Polk PSW111), driven by a Denon AVR-S510BT; the system is VERY musical. She was delighted - and so was I. They are excellent bookshelf speakers at a budget price. Couldn't be more pleased. The purchasing experience with Crutchfield was first-rate, and the assistance provided by my advisor was courteous and helpful. Will certainly do business with Crutchfield again.

Pros: Silky, detailed highs. Very rich, musical mid-range. (Should be paired with a good sub for an outstanding small system.)

Cons: Not really a problem, but couldn't remove the plastic plugs in the 5-way binding posts in order to use banana plug connectors - simply ended up using a bare wire connection. Wasn't my preference, but the end result (excellent sound) more than made-up for the minor frustration.

Please, Audiophiles Only!

Audiolad from Georgia on 11/7/2015

Verified customer (What's this?)
Verified employee purchase (What's this?)

I laugh when people copy what part of what a reviewer wrote about the speakers, and I will at the end. I have very expensive Paradigm Bookshelf speakers in my study, with a nice Rega turntable, Parasound preamp and amplifier, and so on. However, in my office I wanted a less expensive system to use while I work on my computer. I reduce the quality to the Denon DP300F with a Grado Prestige Blue, Marantz Integrated amp, Vincent MM/MC phono preamp, a very good older model Klipsch 8" downfiring sub (this is key), and the B1 pair or speakers. If you don't understand why I ordered the B1 instead of Klipsch, Infinity, Polk or other big box speaker, then you probably should buy this speaker. First it gives a solid 65-18,000 Hz reproductions, but many are so used to the piercing tweeters, they don't understand the beauty of the slightly veiled top end of the B1. This speaker is made for long term listening, and they purposely didn't actenuate the top, but don't kid yourself, the frequency is there in proportion to the other frequency. Now lets begin with the history of the B1 (25 years and counting). Since 2007 (when Stereophile first added the new model as Budget Speaker of the Year), they have and are still rated in the recommended speaker 2015. In 2007, when the speaker was first tested (read article in Stereophile), the results were the transients in this speaker are exceeded only by the best electrostatic speakers. If you don't have the ear, don't buy them.

Pros: Transients, balanced output, detailed beyond belief.

Cons: By design it doesn't have energy below 58 HZ. It messes very well with a quality subwoofer, but recommended not greater than 8".

Just a terrific speaker for a small room. I am a classical music listener and these sound fantastic with inexpensive stands and my NAD 320BEE two-channel amplifier. Clean, great soundstage, no congestion. I only listen at reasonable volume levels and these are a wonderful find.

PSB Alpha B1

Steve M from Lincoln, California on 8/10/2015

Verified customer (What's this?)
Verified employee purchase (What's this?)

I was disappointed with these speakers in light of all the excellent reviews in Crutchfield and elsewhere on-line. The midrange and mid-bass were very good but the speaker seems to be deficient somewhat in its high-frequency detail and extension. I bought these for a desktop system that includes an AudioQuest Dragonfly V1.2 DAC and a Denon RCD-M40 mini cd-receiver (from a Denon D-M40 micro desktop stereo; the speakers that come with the D-M40 are decent but I wanted an upgrade). I bought both the Denon and Dragonfly from Crutchfield and am very happy with them. The Denon has ample power to drive the PSB's to more than adequate listening levels, especially for my desktop. From the moment I hooked them up, however, I noted that the highs did not have the articulation or definition or "air" that my JBL 4408 monitors have in my main system or that my Grado SR80 headphones have. On any given mp3, for example, I could plug in the headphones and hear significantly more high-frequency content and definition than was present from the PSB's. It seemed to me like the mid-bass/midrange driver in the PSB was superior to the tweeter being used, or maybe that the crossover was rolling off or otherwise constricting the highs above a certain point. I don't know, but I returned them and subsequently bought a pair of NHT SuperOne 2.1 speakers that I am extremely pleased with. As usual, Crutchfield's service on this and all my previous transactions has been excellent.

Pros: Great mid-bass/midrange; good-looking speaker; appears to be well-made.

Cons: Somewhat lacking in high-frequency resolution/extension/detail.

Unbelievable detail at the mid bass / high note level. More bass than I expected for this size and price of speaker. It actually looks good and does not take up much space. If your looking for an outstanding sound and value this is it.

Great Speakers

RoseD from Michigan on 12/22/2014

Verified customer (What's this?)
Verified employee purchase (What's this?)

I am not experienced at all in how to review speakers. However, when I shop for anything, I read a ton of reviews and as much information about whatever I'm considering purchasing, plus I look at other comparable items from other companies so I can compare as many things as possible. I was "sure" I wanted to buy BOSE speakers, because they're supposed to be so "great" (and I love the BOSE speakers I have with my computer -- small but powerful!) -- well, when I compared these speakers with some BOSE speakers that were $50 more, one of the things inside the speakers (can't remember what it was) was made out of paper or cardboard, and these speakers had "rubber" for the particular "part" that was inside the speaker (and I know I sound ignorant, because I am about these things), but the point is, I was not happy with some of the things I saw when comparing the BOSE speakers I was looking at with these particular speakers (and I wanted bookshelf speakers at a reasonable amount of money with as good a sound as possible). So, I looked at a few other bookshelf speakers around the same price, and the reviews were really good considering what I wanted for what I could afford and for a certain quality that I was NOT willing to sacrifice. Needless to say, when my husband hooked up these speakers, I was really pleased with the sound! I give them a 5-star rating because of overall quality, reasonable price and a pretty big sound, and the fact that they look great! I recommend these!!

Exactly as expected

JohnP from Los Alamos, NM on 11/2/2014

Verified customer (What's this?)
Verified employee purchase (What's this?)

These are exactly as expected, since I already own 2 pair. PSB is my favorite speaker line from top (Stratus Gold i) to bottom (Alpha B1). I own 17 PSB speakers. This is the best speaker for the price, period. I frequently loan out a pair to friends with more expensive but lesser brands. They then buy PSBs. I will use this pair with my Heathkit AR1515 receiver in my den. In a absolute scale, these would be 3 star, but that would not be fair, since 5 stars would be B&W 801 and PSB Stratus Gold i.

Pros: They are easy to drive (high impedance, low reactance), have good range and excellent dynamics. They are inexpensive, and relatively insensitive to room location. You could build a very nice system around these with a good subwoofer to cover the lows. The sound is very smooth, with no apparent emphasis or thinness. No boominess from trying to fake low frequency extension and no stridency on any material I listen with. They also look nice, despite the vinyl finish.

Cons: Low end is missing, but that is the price for a small enclosure, low price, and smooth sound. With a sub, no downsides at all.

Bought the last pair available in the store in Bergen and still breaking them in, these small giants reproduce especially fast music like nothing I´ve heard. Listening to Koan´s When the Silence is Speaking, converted by a cheap DacMagic and driven by an old Electrocompaniet AW60 amp, they just pour out a wealth of articulated and detailed music. Some sibilance on female vocals which I´m told will disappear with use. If you come across these just get them.

I'm blown away by the musicality and sound space of the small, entry level speakers.

Pros: Simply fabulous in the mid-range, especially on vocals and instruments like the clarinet, violin, etc.. The sound space is great as well - "sounds like you're there". Big sound, especially in a small or medium sized room.

Cons: As you would expect from small bookshelf speakers, bass output will be lacking if you are listening to music that wants that. Add a subwoofer in that instance.

PSB Alpha B1

LY from Metro-Detroit on 11/18/2013

Verified customer (What's this?)
Verified employee purchase (What's this?)

I purchased a pair of these over 7 years ago for a dedicated 2 channel system. Fantastic budget speakers. Since then, I have incorporated the Alpha B1's into a 5.1 system with 2 Alpha LR1's, a CLR1 center channel speaker and a Velodyne sub that I had purchased in the late 1990's. Explosive dynamics, clear dialog and great surround effects. I still listen to 2 channel on that system, periodically, through the Alpha B1's despite having upgraded my 2 channel system considerably over the years. Next I need to buy a new surround receiver. Crutchfield will be the obvious source.

Pros: Very neutral and surprising bass extension for their size and price.

Cons: They really need to be played at slightly higher volume to sound their best so they shouldn't be paired with cheap, low power amplification.

These are excellent budget speakers. You will be surprised how solid and attractive they are. They have a nice soundstage, and a balanced tonality. The bass is not deep, but they are bookshelves, so no one would expect that. I can't imagine someone not being happy with these for the price. I also cannot imagine someone thinking there is a better speaker at this price point. Maybe for a hundred more, you could get a little improvement, but not at this price. Deservedly an audio classic, and the ultimate entry point for anyone looking to lock into audio quality.

Surprising sound, modest price

OMS from Falmouth, MA on 11/18/2011

Verified customer (What's this?)
Verified employee purchase (What's this?)

I have to say I've been surprised and impressed by the sound coming from the Alpha B1s, from the overall smoothness and balance to the surprising bass to the mids, which are the "special" strength of this model. I have owned significantly more expensive tower and bookshelf speaker speakers, and the Alphas do not compete on output or size (nor did I expect them to). I would probably also agree with some reviews which have noted that the treble extension is not as effortless as with some bookshelf models starting at about double the price. However, the overall impression is much better than I had expected, and they fill their (moderately-sized) space very admirably for two-channel listening without a sub. The metal grille is also a plus as far as being relatively kid-proof.

Pros: Mids, overall balance, well-rounded bass. Understated appearance. Very surprising performance from a bookshelf speaker of this price and size.

Cons: Not much, actually. Maybe it would be nice if Crutchfield carried some of the other finish choices.

Features

Two-Way Design: The PSB Alpha Series B1 bookshelf loudspeaker features a true two-way design that employs a single 5.25" mid-woofer paired with a single .75" ferrofluid-cooled tweeter. The result is an extremely tight sound with excellent imaging characteristics

  • 0.75" Tweeter w/ WaveGuide: Each Alpha Series B1 loudspeaker is equipped with a 0.75" aluminum dome, ferrofluid-cooled tweeter for crisp, clear highs. The B1 bookshelf speaker's tweeters utilize an acoustical waveguide to deliver, more even high frequency response, no matter what part of the room you're in.
  • 5.25" Woofer: Each PSB Alpha Series B1 speaker employs a 5.25" injection molded metalized polypropylene woofer with rubber surround for accurate, detailed midbass.
  • Crossover Network: The tweeter and woofer are crossed over at 3,000 Hz.

Bass Reflex Cabinet: The PSB B1 loudspeaker utilizes a bass reflex enclosure with a rear-firing port for greater efficiency and bigger bass response. The PSB Alpha Series B1 bookshelf speaker features a black wood grain vinyl cabinet that matches almost any decor. The speakers come with removable aluminum (metal-mesh) black grilles.

5-Way Binding Posts: The 5-way binding posts will accept bare wire (up to 12-gauge), pin connectors, spade connectors, and banana plugs (single or dual). The speaker's binding posts are color-coded (red/black) for easy identification between positive and negative.

Mounting Options: The PSB B1 loudspeakers include eight self-adhesive rubber feet to safely and securely place the speakers on floor-stands or other AV furniture. Each PSB Alpha Series B1bookshelf speaker also features a single keyhole slot and dual 1/4"-20 threaded insert to wall-mount the speaker. Each Alpha Series B1 speaker has a single keyhole slot on the back panel to easily wall-mount the speakers. Each B1 loudspeaker also features dual 1/4"-20 threaded inserts to wall-mount the speakers using optional articulating brackets (sold separately).

Placement: The positioning of the left and right speaker can play a major role in their acoustic performance of a pair of loudspeakers. The position of speakers in relation to the walls, floor, and ceiling of your listening room will also often affect the way a speaker sounds.

  • Positioning: The optimum placement height for bookshelf speakers should typically be set with the tweeters at about the same height as your ears when seated. Generally, you will receive the best imaging and other spatial qualities if the speakers and your listening position form an equilateral triangle, with the speakers not quite as far apart from each other as your position from the speakers. If your favorite listening position is equally distant from both speakers, angling or "toeing" the speakers inward about 5 to 10° usually produces the best convergence of high frequencies for that listening position. Different listening positions may require different angling.
  • Room Boundaries: For the greatest bass response and feel, place the speakers near three adjoining surfaces - in a corner of a room near the floor or ceiling - where the convergence of the two walls and floor/ceiling produces an amplifying effect that resembles megaphone-like sound. Placing a speaker away from all room boundaries will produce the least amount of bass, however your own listening preferences should decide what proportion of bass response is ideal for each room setting and space.

Alpha Series: The all-new Alpha Series has been rebuilt with enhanced custom drivers and a new crossover design that work perfectly together to deliver natural, detailed sound with precision and less distortion. PSB's Alpha Series of loudspeakers offer five models (T20 Tower, P5 Bookshelf, P3 Bookshelf, B1 Bookshelf, and C10 Center) to fit the needs of almost any audio setting. The Alpha Series of speakers offers audiophile sound quality at an affordable price; but not at the expense of appeal, style, and sound.

Note: Every PSB Alphas Series speaker is meticulously tuned and tested at Canada's national research facilities to deliver the most accurate acoustics under the most demanding of listening conditions.

Optional Powered Sub: Add a PSB SubSeries powered subwoofer (sold separately - see Accessories Tab) to the Alpha Series loudspeakers for an even more immersive listening experience with bigger bass response.

I want to upgrade my denon dm40 speakers. Replacing 6ohm 83db sensitivity for 6ohm 91db sensitivity. This is for better mid and highs. Note: this is paired with polk PSW111 subwoofer. [ Larry  Oct 07, 2017 ]
A
needed new "bookshelf" speakers [ Donald  Dec 06, 2016 ]
A
I originally bought these speakers based on the reviews in Stereophile magazine and based on the frequency response curves across the audio band (20-20KHz). It is a flat response speaker. (i.e. no colorations added) This is like the old "AR" speaker sound that I love for my classical music and opera. I am an engineer/audiophile as well as a bass choral singer, so I am very attuned to voice and symphony orchestra music and the way I want it to sound. [ Kelvin  Nov 16, 2016 ]
A
These match my little surround sound set up, with PSB Alpha 1 RL fronts and a PSB center. [ Les  Mar 06, 2016 ]
A
I understand these to be good entry level speakers that will work well with the turn table system I'm building [ Ned  Mar 04, 2016 ]
A
The last time that I had heard these speakers was in 2007 when I was an installer for a high end audio shop (lots of B&W and mangnapans). Obviously they made a large impact on me and were considered by many as the best speaker per dollar on the market. [ Jeremy  Dec 09, 2015 ]

Can these be used as height speakers in an Atmos setup? planning to wall mount them

Hi, Ron. My Alpha's are currently being used in a 2.1 configuration on my computer, attached to a 2012 Yamaha 5.1 receiver. Any bookshelf speaker will work, and having the mounts on the speaker back are a plus. One caveat: The alpha's need more volume (power). The Elac Debut speakers are sweet and my favorite, but also bigger, heavier, still 6 ohm and no mounting consideration. I have the Elac B5 's and UniFI's in two different areas of the house, also 2.1 configured because I listen to alot of music. BTW the Alpha's were Crutchfield "scratch & dent'"-- in perfect condition inside and out. Regards

Q
I am interested in the PSB Alpha B! speakers to match to my computer. Q1. is an amplifier required? If so what are your recommendations? 2. If amplification is needed, would a computer graphics card provide the necessary amplification? Please explain. Q3. Can Crutchfield inform me of Black Friday specials on the PSB Alpha B! speakers, the PSB Alpha PS1 speakers and the Alpha 1-100 powered media system? Thank you.

A
The speakers require a minimum of 10 watts input, and that is far to low for good listening. In my opinion, you would require a power amp from your analog output of your soundcard to get the sound these speakers are capable of.
[ Les  Nov 20, 2017 ]
A
These are not powered speakers, so you will need to get an amplifier (90 Watts should be sufficient). Fortunately, Class-D amps these days are cheap and very good (low THDN, high efficiency). You should be able to get one off here with an aux input for under $100. Graphics cards normally don't provide enough current to supply unpowered speakers, so you probably will need an amp.
[ Addison  Nov 18, 2017 ]

Hi Bob, Yes the PSB alpha does require an amp, a min of about 40 wpc should be good, not sure if a sound card has power out most the time there line level, buy a small amp like the nad or somthing and it will sound realy good.
