PSB AM3 Compact Powered Speakers

What You Need to Know

A Complete Hi-Fi System That Fits on a Desk

The PSB Alpha AM3 packs a genuine stereo system into two compact cabinets under nine inches tall. Amplification, a phono stage for your turntable, a DAC for digital sources, and aptX Bluetooth are all built in—just pair and play. Whether you're spinning vinyl, streaming from your phone, or upgrading your TV or desktop sound, the AM3 delivers bold, studio-quality stereo with nothing else to buy.

The Legendary Alpha Pedigree

Since 1991, PSB's Alpha Series has been the reference benchmark for entry-level hi-fi, built on nearly 50 years of acoustic research at Canada's National Research Council. The AM3 continues that lineage with a 0.75-inch aluminum dome tweeter (ferrofluid-cooled, neodymium-powered) and a 4-inch woofer with rubber surround in a bass-reflex cabinet. A 35-watt-per-channel amplifier with DSP optimization—engineering shared with sister brands NAD and Bluesound—tunes frequency response, bass extension, and output beyond what a passive design this size could manage.

Every Input You Need, Sold by Pair

A dedicated moving magnet phono input connects your turntable directly—no external preamp. Optical serves your TV, USB your computer, 3.5mm anything else, and aptX Bluetooth streams in near-CD quality. A subwoofer output stands ready when you want deeper bass. Choose Matte Black or Matte White, each with detachable magnetic perforated-metal grilles.

Frequently Asked Questions

Do I need an amplifier or receiver?

No—amplification is built in, along with the phono preamp, DAC, and Bluetooth. Connect your sources, plug in the power, and you have a complete stereo system.

Can I plug my turntable in directly?

Yes. The dedicated RCA phono input includes a built-in moving magnet preamp, so any standard MM turntable connects straight in. The AM3 plus a quality table makes one of the simplest great-sounding vinyl setups you can buy.

Will they work with my TV or computer?

Both. The optical input takes digital audio from nearly any TV for a massive upgrade over built-in speakers, and the USB input makes the AM3 an exceptional desktop system for music, meetings, and games.

Can I add a subwoofer later?

Yes—a dedicated subwoofer output connects to any powered sub, such as PSB's SubSeries models, for full-range bass whenever you're ready to grow the system.
