PSB Alpha iQ, white (pair)

Alpha iQ

Active Streaming Speaker with BluOS

As a simplified audio approach, the Alpha iQ comes with a built-in digital amplifier and BluOS streaming, so you can access and control everything from streaming services and digital music collections to EQ settings and multi-room speaker management. A versatile addition to any home audio system, whether in a stereo setup, a home theater, as TV speakers, or as bookshelf speakers.

Since 1991, the PSB Alpha series has upheld design standards of simplicity, compactness and versatility. The Alpha iQ reimagines the legendary Alpha speaker for the next generation by integrating a built-in amplifier, streaming capability and BluOS multi-room technology into a pair of wireless bookshelf speakers. The result: a revolutionary all-in-one system that combines convenience with uncompromising audio quality.

Behind the Alpha series

The Alpha series was first designed and built in a small Canadian town in 1991, starting with the simple idea of developing affordable speakers focused purely on performance. With passion and dedication in the pursuit of a naturally sounding speaker, and by drawing on decades of research by PSB founder Paul Barton at the Canadian National Research Council, the Alphas quickly became one of the most celebrated speakers in the world and remain the benchmark for entry-level Hi-Fi speakers today.

One app control

The BluOS Controller app simplifies streaming and controlling your music with a single app that connects automatically to the Alpha iQ thanks to a fully integrated network connection. Enjoy lossless music at up to 24-bit/192kHz without delay or loss of sound quality, streamed wirelessly to any room in your home. Easily control all your music from anywhere in the house with the fully featured BluOS Controller app for iOS and Android devices.

Serious sound

PSB's Alpha iQ speakers feature a 4-inch polypropylene mid-woofer and a 0.75-inch aluminum dome tweeter with neodymium magnet and ferrofluid damping. Thanks to powerful amplifiers, tuned bass ports and DSP-enabled low-frequency extension, the Alpha iQ reveals the signature PSB sound while delivering bass output that thoroughly outclasses its small size.

True all-in-one

The Alpha iQ is no average pair of stereo speakers. It's a compact, minimalist bookshelf speaker system that serves as a true all-in-one music system. With its elegant enclosure and sleek touch panels, the Alpha iQ can be placed anywhere in the house. Wireless stereo pairing eliminates cable clutter, since only a power connection is required. The unique placement of the tweeter below the woofer ensures consistent sound quality whether you're sitting or standing.

There's more to it

The Alpha iQ isn't just a complete music system — it can also be a versatile addition to your home audio setup. Choose whether to stream from countless services in the BluOS app, connect it to a turntable, or elevate your TV shows, movies and games with incredible sound. With multi-room capability, you can set up several iQ pairs throughout your home and control the music in every room with a few taps in the BluOS app. There's nothing else quite like the Alpha iQ — it's a unique solution that revolutionizes your approach to home audio.

Frequently asked questions

Do I still need an amplifier or streamer for the PSB Alpha iQ?

No, both are already built in. Each speaker has its own power amps with 30 watts for the tweeter and 60 watts for the woofer, plus an audiophile DAC up to 24-bit/192kHz and the BluOS network streamer. You just need power, your network, and the BluOS app on your phone.

Can I connect a TV and a turntable?

Yes, both are supported. The Alpha iQ has an HDMI eARC input for the TV, an optical digital input, a 3.5mm analog input and a phono MM input for turntables with an MM cartridge. That way your living room runs through a single pair of speakers — music, movies and vinyl included, without an extra box on the shelf.

Do I need a paid streaming subscription?

No, a subscription is not required. The BluOS app also plays your own digital music collection from the network, and via Bluetooth, AirPlay 2, the turntable input or the TV, music comes through without any service at all. Streaming services like Tidal Connect or Spotify Connect are an option, not a requirement.

How many cables do I need between the two speakers?

None. The two Alpha iQ units pair wirelessly into a stereo pair, so classic speaker cables are eliminated entirely — only the power connection remains. That makes placement flexible: sideboard, shelf, desk. The tweeter sits below the woofer, so the sound stays consistent whether you're sitting or standing.

What room size suits the Alpha iQ?

Small to medium-sized rooms. The 4-inch mid-woofer with tuned port and DSP-enabled bass extension covers on-axis from 64 Hz to 20 kHz (±3 dB) and down to 35 Hz (-10 dB) — plenty of foundation for this format. In very large living spaces it eventually reaches its limits; tell us a bit about your room.
