Reviewers' Choice – Soundstage! Network
Streaming Powered Speakers with BluOS
Alpha iQ Steaming Powered Speakers with BluOS make it easy to enjoy PSB’s signature "True to Nature" sound from your favorite streaming services and legacy sources – without cable clutter. The two speakers have 180W of built-in amplification and a network streamer based on the award-winning BluOS multi-room music platform.
Award-Winning Performance
The Expert Sound and Imaging Association (EISA) gave the Alpha iQ Steaming Powered Speakers its Best Wireless Bookshelf Speakers Award for 2024-2025.
"Designed with both performance and ease of use in mind, PSB’s Alpha iQ is the first active stereo speaker system to incorporate the BluOS platform, tying it into a multiroom ecosystem with slick app control and music playback options. With further connections including AirPlay, aptX HD Bluetooth, HDMI ARC and MM phono, the Alpha iQ accommodates a modern mix of wired and wireless sources, while its performance is equally crowd-pleasing."
Reviewers' Choice Award
The Alpha IQ won a Reviewers' Choice Award from Soundstage! Network. According to reviewer Gordon Brockhouse, "PSB’s diminutive Alpha iQ streaming active loudspeaker system delivers sound that’s far weightier than your eyes would lead you to expect. The sound isn’t just big; it’s also refined. Throughout my listening, I was impressed by the Alpha iQ’s timbral neutrality, soundstaging, and portrayal of fine detail."
"Combine its excellent sonics with the abundant connectivity options and the excellent BluOS streamer, and you’ve got a winner. Highly recommended."
"A Top-Tier Option"
"PSB’s handsome Alpha iQs deliver highly accurate sound – no surprise from this well-established Canadian maker – and a wide range of streaming features," reports Daniel Kumin, techradar.com, December 17, 2023. "For anyone looking for a music-first soundbar alternative, the Alpha iQs present a top-tier option."
"Surprisingly full and powerful sound. Clear center image for dialog and vocals." Notes Ryan Waniata, ticking off all the Alpha IQ advantages for wired.com , August 12, 2023. "Smooth and detailed upper register. Simplified connection for all your devices. Feature-rich app with multi-room audio connection. Multiple ways to stream. High-resolution support. Small profile blends in with your decor."
A Huge "Sensation of Space"
"The sensation of ‘space’ is one of the true and unarguable strengths of the PSB system," reports Simon Lucas, hifiplus.com , December 5, 2023. "The soundstage it summons is out of all proportion to the size of the speakers from which it emanates, and it’s properly organised and arranged. Elbow-room is significant, even in dense recordings or Madvillain-style cut-and-paste collages, and it makes for an informative and easy-to-follow listen. It doesn’t do any harm that the system is so tonality consistent, either – there’s an impression of unity and singularity from the top to the frequency range."
Easy to Set Up and Use
Alpha IQ speakers are easy to set-up and use. Plug them into power outlets, then connect the Alpha iQ to your home using the friendly BluOS Controller app. Now you can play music from more than 20 streaming services and share that music over your home network with up to 63 other BluOS-enabled components. In addition to Apple AirPlay 2 support and Bluetooth connectivity, the Alpha iQ has inputs for a wide array of sources, so you can connect a turntable, TV, disc player, and game console, as well as other audio sources.
A World of Music at Your Command
Consisting of two wireless bookshelf speakers with built-in amplifiers, PSB’s Alpha iQ is an all-in-one audio system for the streaming age. There’s no need to clutter your living space with speaker cables. The left and right speakers communicate via a wireless link that can cover most rooms in an average-size home without delays or latency, so music stays synched and clear regardless of speaker placement.
The BluOS network streamer provides access to more than 20 streaming services, including several that offer lossless and high-resolution audio, such as Amazon Music, Deezer, Idagio, Qobuz, and Tidal. The Alpha iQ supports Apple AirPlay 2, so you can stream audio from any app on an iPhone, iPad, or Mac. Spotify Connect and Tidal Connect are also supported, so you can cue up music in the apps for those services then transfer playback to the Alpha iQ.
The Alpha iQ has an audiophile-grade DAC that supports high-resolution audio resolution to 24-bit/192kHz, and has full MQA decoding and rendering capability for high-res streaming from Tidal. BluOS also gives you access to hundreds of Internet radio stations around the world, including Radio Paradise, which offers four stations with MQA-encoded hi-res music.
You can listen through the Alpha iQ alone or share your music over your home network with as many as 63 other BluOS-enabled devices.
Designed for Serious Sound
Featuring a sleek, modern design, the Alpha iQ is available in satin white and satin black finishes. Inside each enclosure is a 4″ polypropylene mid-bass driver with steel basket and rubber surround, and a 0.75″ aluminum dome tweeter with neodymium magnet and ferrofluid damping.
The Alpha iQ employs a DSP-based active crossover. As with many PSB designs, the tweeter is placed below the woofer. With this arrangement, the blend between woofer and tweeter remains consistent whether you’re sitting or standing.
Each woofer has its own 60W class-D amplifier, and each tweeter its own 30W class-D amp, for total system output of 180W. Thanks to their powerful amplifiers, tuned bass ports, and DSP-enabled low-frequency extension, PSB’s Alpha iQ speakers deliver bass output that completely belies their diminutive size.
Easy Plug and Play Set-up and Operation
The Alpha iQ isn’t just for streaming. The primary speaker has a built-in MM phono preamp and RCA jacks plus ground terminal, so vinyl fans can connect a turntable. An HDMI ARC port lets you experience "True to Nature" sound with TV and movies. There’s also an optical input for connecting a disc player or game console, and a 3.5mm auxiliary input for connecting analog sources.
The Alpha iQ has Bluetooth connectivity, with support for the high-quality aptX-HD codec for wireless playback from smart devices. You use the BluOS app to play music files stored on an external drive connected to the Alpha iQ’s USB port.
The combined optical/headphone jack lets you connect a pair of headphones for late-night listening. For enhanced bass, there’s a subwoofer output. When a subwoofer is connected, you can use the BluOS app to engage a low-pass filter for the sub and a high-pass filter for the main speakers. This frees the Alpha iQ from having to produce deep bass sounds.
Super Smart
Available for Android, iOS, macOS, and Windows, the intuitive BluOS app lets you control every aspect of the Alpha iQ’s operation. Convenient touch controls on the top of the primary speaker let you adjust volume and pause and resume playback.
You can also control playback by voice using Amazon Alexa, Google Assistant, and Apple Siri (via AirPlay 2). And PSB’s Alpha iQ BluOS Streaming Powered Speakers can be integrated into popular smart home systems like Control4, Crestron, ELAN, RTI, and URC. IR command learning is available for listeners who use harmonized remote controls to operate multiple A/V devices.
Truly, the PSB’s Alpha iQ sets a new benchmark for modern, tangle-free, audiophile-grade listening. It gives you beautiful sound made simple.
