PSB Alpha iQ MQA Multi-Room Wireless Bluetooth/WiFi Desktop Bookshelf Speakers (with HDMI & Phono Built-in) - White

Designed according to PSB's "True to Nature" sound, 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 speakers also employ a DSP-based active crossover. As with many PSB designs, the tweeter is placed below the woofer.

Each woofer has its own 60W class-D amplifier, and each tweeter its own 30W class-D amp, for a total system output of 180W. Thanks to the powerful amplifiers, tuned bass ports, and DSP-enabled low-frequency extension, the Alpha iQ speakers will deliver a bass output that completely belies their diminutive size. And there's also a subwoofer output. When a subwoofer is connected, BluOS engages a low-pass filter for the sub and a high-pass filter for the mains, which frees the Alpha iQ speakers from having to produce deep bass sounds.

The Alpha iQ’s hifi quality DAC supports resolutions up to 24-bit/192kHz and has full MQA decoding and rendering capability for high-res streaming from Tidal Masters. BluOS also lets listeners enjoy four stations with MQA-encoded high-resolution music from Radio Paradise.

Listeners can manage every aspect of the Alpha iQ’s operation using the rich, robust BluOS Controller app, which is available for Android, iOS, macOS, and Windows. For making quick adjustments without using the app, there are touch controls on the top of the primary speaker for changing volume and pausing and resuming playback. Voice control is also possible using Amazon Alexa, Google Assistant, and Apple Siri (via AirPlay 2).

Like all BluOS-enabled components, the PSB Alpha iQ BluOS Powered Speakers can be integrated into popular smart-home systems, including Control4, Crestron, ELAN, RTI, and URC. IR command learning is available for listeners who use harmonized remote controls to operate multiple A/V devices.

"The Alpha iQ is a perfect choice for music-lovers who want a sophisticated all-in-one system that delivers great sound without the fuss of cables and multiple components," says Joe de Jesus, product manager, PSB Speakers. "We think of it as beautiful sound made simple."
