Highlights & Key Technologies

A Simpler Way to Listen
The iQ1 gives you dedicated left and right channel sound in a setup that's easy to enjoy right away. Built-in amplification helps music, movies, and vocals sound more open and detailed. Whether it's part of a desktop setup or your main living space, the iQ1 brings more depth and separation to everyday listening.

Built for Everyday Listening
The iQ1 combines streaming, amplification, and digital processing into a single connected system that works right out of the box. Each pair delivers 270 watts of system power from a TI-based Class-D platform, with dedicated amplification for each driver. Whether it's part of a desktop setup, living room, or smaller listening space, the iQ1 brings clear, room-filling sound into more places around the home.

Compact Speakers, Full Sound
Each speaker features a 4" (100mm) polypropylene mid-bass driver and a 0.75" (19mm) aluminum dome tweeter, powered by dedicated Class-D amplification. A DSP-based active crossover, tuned ports, and low-frequency extension work together to produce detailed mids, controlled bass, and clear highs. The result is balanced sound that feels natural across music, movies, and everyday listening.

Streaming Made Simple
The BluOS Controller App gives you easy access to more than 20 streaming services, including lossless and high-resolution options, your personal music library, and multi-room playback through one app — and you can move from TV audio to vinyl without changing devices or inputs manually. Support for 24-bit/192kHz audio, AirPlay 2, Spotify Connect, and Tidal Connect gives you multiple ways to listen without changing how you already enjoy music. As your setup grows, BluOS lets you add more compatible speakers throughout the home and control everything from one place, with playback to up to 63 additional BluOS-enabled components. The iQ1 also offers integration with Control4, Crestron, ELAN, RTI, and URC, IR learning capability for remote control integration, and voice control support via Alexa, Google Assistant, and Siri (via AirPlay 2).

Sources Beyond Streaming
A built-in MM phono preamp makes it easy to connect a turntable, while the BluOS Controller App can bypass the phono stage for use with line-level sources such as CD players or turntables with built-in preamps. HDMI eARC handles TV audio, while optical, USB-C (input for playback), and USB-A (input for external storage devices) add flexibility for additional sources. Bluetooth with aptX Adaptive rounds out wireless playback from smart devices, and a subwoofer output with DSP-enabled low-pass and high-pass filters completes the connections.

A Direct Stereo Connection
The iQ1's left and right speakers connect using a single included cable, keeping setup clean and dependable. Once connected, both speakers stay perfectly synchronized for consistent stereo playback across music, movies, and everyday listening. It's a simple, dependable connection that helps maintain consistent stereo performance while keeping the system approachable and easy to use.

Designed for Everyday Spaces
The iQ1 is made to fit comfortably into smaller rooms, shelves, desks, and media consoles without taking over the space around it. Its clean cabinet design, cloth grille, and durable finish give it a modern look that feels easy to live with every day — understated and modern. Available in Black and White, the iQ1 blends naturally into a wide range of rooms and listening setups.
