Fantastic PSB sound in a compact design
Fantastic PSB sound in a compact design
The compact PSB Alpha PS1 powered speaker system can fit on even the most space-challenged desks and bring your music to life with surprising punch. To be honest, we're not really too surprised. That's because PSB conducts rigorous testing and research at Canada's National Research Council to ensure all their speakers deliver outstanding performance in the real world. No tricks here, just solid, thoughtful engineering for refined, true-to-life sound. Add in the beautiful high-gloss finish, and you have a speaker that's ready to impress.
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.

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.
