PSB Alpha PS1 powered speakers

Turn your desktop into a concert hall

Despite their tiny footprint, these speakers have the power to fill a small- to medium-sized room with rich, robust sound. They each feature a 3-1/2" metalized polypropylene woofer and 3/4" aluminum dome tweeter designed to deliver the same smooth response off to the sides of the speaker as directly in front. This allows the Alpha PS1s to "disappear" while projecting a large and detailed soundstage. And the speakers' rounded shape offers a stylish look for your desktop.

Quick and simple set up

Hooking up these speakers is easy and straightforward. RCA and minijack inputs let you listen to music from your computer or a portable player, like an iPod®, or another audio source. A line-level subwoofer output makes it easy to expand  your system to include an optional powered subwoofer. The Alpha PS1 also includes a 2 x 20-watt power amplifier built into the left speaker, so you just make a simple connection between the left and right speakers using the included cable. The universal power supply with both EU and US power cords works with any AC voltage, making it convenient for world travelers.

Great speakers at a great price. The acoustics are great; can hear the tiniest of sounds clearly. They were such an improvement in listening experience, we added the sub-woofer to enhance the lower tones. That was another step up in listening quality. We could not be more pleased.

Features

Alpha PS1 Powered Speakers: The PSB Alpha PS1 Power Speakers combine PSB's most popular Alpha Series speaker design with a built-in amplifier to make a versatile desktop solution with enough acoustic output for a small to medium sized room. The Alpha PS1 Powered Speakers are true hi-fi speakers engineered to upgrade today's audio and desktop listening experiences. Benefiting from forty years of proven acoustic excellence, these speakers use highly efficient amplifiers and state-of-the-art circuitry to create a powerful full-range system, transforming your favorite audio files into desktop concert.

True-to-Nature Sound: The Alpha PS1 Powered Speakers are engineered for the true-to-nature sound for which PSB is known. Many small speakers employ tricks like exaggerating the treble or falsely boosting bass to overcome limitations and poor performance, but not so with the Alpha PS1. Using sound research and exhaustive testing at Canada's National Research Council in the nation's capital of Ottawa, the PSB team has designed the Alpha PS1 with extremely smooth and refined sound. You'll be pleasantly surprised by its output capability and solid tuneful bass response compared to that of the Alpha PS1's diminutive size. The response off to the sides of the speaker has the same smooth response as the sound directly in front, making the Alpha PS1s acoustically "disappear" by projecting a large and exquisitely detailed sound image.

Two-Way Speaker Design: Each PSB Alpha PS1 Powered Speaker houses a 0.75" aluminum dome tweeter and a 3.5" metalized polypropylene cone woofer with a rubber surround and oversized magnet structure. The tweeters utilize an acoustical waveguide to deliver, more even high frequency response. The polypropylene woofers provide accurate, detailed midrange/midbass.

Digital Amplifier: The Alpha PS1 Powered Speakers are powered by highly efficient 20-watt x 2-channel RMS (40W x 2ch Peak) Class D amplifier which is built into the left speaker.

Bass Reflex Enclosure: The Alpha PS1 Powered Speakers feature an acoustically engineered ABS cabinet with UV coating. This bass reflex enclosure features a tuned slot port on the rear of the cabinet which extends low bass response.

Rear-Mount Volume Control: The PSB Alpha PS1 Power Speaker (Left) features a rear-mounted rotary volume control.

Analog Inputs: The PSB Alpha PS1 Power Speaker (Left) is fitted with a stereo RCA input and stereo minijack (3.5mm) input to connect an external audio source; such as your MP3 player, smartphone, tablet, laptop, computer, or TV. 

Subwoofer Output: For those dynamic lows, a subwoofer output (mono-RCA) on the rear-panel of the left speaker allows you to connect a powered subwoofer.

USB Charging Port: The Alpha PS1 Powered Speaker (Left) is equipped with a USB (type-A) power port to charge your USB-enabled device; such as your smartphone or tablet. The USB charging port is rated at 5V/500mA.

AC Power Supply: The Alpha PS1 Powered Speakers operate off of standard household AC current using the supplied universal power supply. The AC power adapter plugs into the left speaker, while the 6.5' PowerLink cable connects power to the right speaker.

Optional Speaker Stands: The PTB-1 tilt base (760PTB1, sold separately) is designed specifically for PSB's Alpha PS1 powered speakers. You can mount the PTB-1 to the Alpha PS1 to angle the speakers upward or flat for bettering stereo imaging, based on speaker placement. Two bases are included. Each base mounts to the bottom of the speaker using four machine screws. Each base also includes four self-adhesive rubber pads to provide safe and secure placement of your speaker.

Crutchfield asked  
Why did you buy this?

Outstanding sound reproduction, a nice wide soundstage presence. The PSB Alpha PS1's are perfect for listing to FLAC/ALAC/HI-RES music files. The definition in the instruments is phenomenal. Although the bass is limited due to their size, when paired with a good sub, the sound truly shines. [ Robert  Jun 13, 2017 ]
Recommended component [ Oscar  Jun 10, 2017 ]
I have other PSB speakers I am very happy with. These powered speakers were compact and looked like a good value. [ Bennett  Jan 25, 2017 ]
I have two sets of PSB CS1000 outdoor speakers which are terrific--great fidelity--so I am trusting these will be good as well. The online reviews were also encouraging. [ GARY  Jun 16, 2016 ]

Yes you can hook up two sub series 100s to compliment the PS1 satellite speakers. [ FRED E  Feb 17, 2015 ]
Not that I can see. There is a dedicated sub output on only one of the speakers,I do know how you'd connect a second. [ MARK  Feb 17, 2015 ]
I wouldn't see why not if you used a splitter to split the single sub-out into two. Should be fine. [ William Tyler  Feb 17, 2015 ]
Yes, just use a Y connector and an additional audio cable to connect the subwoofer output of the left channel PSB Alpha speaker to each powered subwoofer. However, as these speakers sound best when they are on a table or counter top directly in front of you I'm not sure why you would want to use more than one subwoofer. [ Dennis  Feb 17, 2015 ]
It doesn't have two outputs but don't see why you can't split the inputs for extra sub [ wayne  Feb 17, 2015 ]
Please note that the PSB Alpha PS1s are themselves not subs. I have had them for a year now, having bowed to my wife's pressure to get rid of my large speakers in our bedroom for smaller items. I made a point to research small speakers with very high sound quality, as I am a music obsessive who now plays my thousands of albums as digital mp3 albums plugged directly into my speakers. These speakers can do that. The sound quality is absolutely excellent. However, I often want to slightly raise the bass, and the only way to do that if you are playing the music from a phone or mp3 player is via an equalizer app. But since you are asking for a sub-woofer, the left speaker has an output for the optional SubSeries 100 powered subwoofer which does a great job of deepening the bass sound. So, be aware that these are not themselves subs but they can accommodate one sub plugged into the left speaker. Again, I cannot stress further what pure and powerful and rich sound comes out of these little critters, whether you play classical, jazz, rock, you name it. I now know you can have small speakers without sacrificing sound. Of course, these are intended for a room in your home. They obviously won't substitute for large speakers that you might crank down in the basement. [ Daniel  Feb 17, 2015 ]
I only have one sub and it sounds great with them. I use them daily for about 8 hours a day. [ Addison  Feb 17, 2015 ]
