2. Chronology and Historical Background: The Evolution of PSB and Active Hi-Fi

To understand the positioning of the iQ series, it is essential to look at the historical trajectory of PSB Speakers and the broader evolution of the high-fidelity audio market.

The Legacy of Paul Barton and the NRC

Founded in 1972 by violinist and designer Paul Barton in Saint Charles, Ontario, PSB Speakers built its reputation on rigorous scientific research. Barton was one of the first loudspeaker designers to utilize the world-class psychoacoustic research facilities at the National Research Council (NRC) in Ottawa, Canada.

For decades, PSB’s design philosophy has been anchored in the findings of the NRC, which emphasize flat frequency response, low distortion, and controlled off-axis dispersion to create a natural, lifelike soundstage.

The Lenbrook Era and the Rise of BluOS

In subsequent decades, PSB became part of the Lenbrook Group, a Canadian brand management company that also owns NAD Electronics and Bluesound. This corporate relationship proved pivotal. While NAD provided expertise in amplification, Bluesound pioneered BluOS—a proprietary, high-resolution operating system designed specifically for wireless multi-room music management.

By integrating BluOS into PSB’s active speaker designs, Lenbrook succeeded in merging traditional Canadian acoustic design with cutting-edge network streaming technology. The iQ series represents the latest chapter in this integration, succeeding previous active models like the Alpha AM3 and AM5, but with a renewed focus on network connectivity and high-resolution streaming.

The Shift from Passive to Active Systems

Over the last decade, the global audio market has experienced a profound shift. Traditional hi-fi systems—composed of separate passive speakers, integrated amplifiers, standalone DACs, and external streamers—have increasingly given way to unified, active streaming systems.

Modern consumers demand systems that eliminate cable clutter and minimize physical footprint without sacrificing the acoustic depth and imaging performance of traditional separates. The iQ series is PSB’s direct response to this shifting paradigm.

Amplification and Crossover Topologies

Both systems are fully active, meaning the crossovers are implemented in the digital domain (DSP) before the amplification stage. This ensures that each driver receives a signal optimized for its specific frequency range, minimizing phase anomalies and maximizing efficiency. However, the allocation of amplifier power differs between the two models:

  • Woofer Drive: In both the iQ1 and iQ2, each 10cm polypropylene woofer is driven by its own dedicated 90-watt Class D amplifier module, ensuring robust control over low-frequency transients.
  • Tweeter Drive (iQ1): In the iQ1, the two 1.9cm aluminum-dome tweeters share a single, two-channel amplifier module that delivers 45 watts per channel.
  • Tweeter Drive (iQ2): The iQ2 utilizes a true quad-amplified design. Each tweeter is driven by its own independent 45-watt amplifier module. This complete separation of the high-frequency amplification chain reduces potential electrical crosstalk and intermodulation distortion, resulting in a cleaner, more precise high-frequency response and improved stereo imaging.

Inter-Speaker Connectivity

The method of communication between the left and right speakers represents another primary differentiator:

  • The iQ1 Tethered Approach: The iQ1 requires a physical, multi-conductor umbilical cable to link the primary (active) speaker to the secondary speaker. While this ensures perfect synchronization and zero wireless interference, it limits the distance between the speakers and requires routing a cable across a desk or media console.
  • The iQ2 Wireless Approach: The iQ2 utilizes a proprietary, high-bandwidth, low-latency wireless link to connect the left and right channels. This allows for clean, wire-free placement across a room, with the only requirement being a power cable for each speaker.

Input and Output Connectivity Options

Both models are equipped with an identical, comprehensive suite of physical inputs on the primary speaker’s rear panel, making them highly versatile hubs for analog and digital sources:

  • HDMI eARC: Allows for direct connection to a modern television, enabling the speakers to replace a soundbar while allowing TV remote control integration via CEC.
  • Optical Input: For connecting legacy digital sources such as CD players or older gaming consoles.
  • USB Audio (Type-A and Type-C): Enables direct, driverless connection to computers, laptops, or external hard drives containing high-resolution audio libraries.
  • Analog RCA Inputs: For line-level analog sources.
  • Moving-Magnet (MM) Phono Stage: A dedicated phono preamplifier circuit, allowing users to connect a turntable directly to the speakers without needing an external phono box.
  • Subwoofer Output: An RCA output with smart crossover management, allowing users to offload low frequencies to an external subwoofer via the BluOS app.

4. Official Responses and Design Philosophy: Integrating Software and Hardware

PSB Speakers has positioned the iQ series as a direct response to the modern listener’s demand for high-performance audio that integrates seamlessly into contemporary living environments.

Additionally, BluOS enables seamless multi-room integration. The iQ speakers can be grouped with any other BluOS-enabled devices—including products from Bluesound, NAD Electronics, and Cyrus Audio—to create a synchronized, whole-home audio network.


5. Implications and Market Context: The Competitive Landscape

The launch of the PSB iQ series introduces a formidable challenger into one of the most fiercely contested segments of the modern audio market: the premium active stereo speaker category.

The Battle with KEF

The primary targets for the PSB iQ series are undoubtedly KEF’s highly successful compact active models:

  • The KEF LSX II LT (£899 / $999): Directly competing with the PSB iQ1, the LSX II LT uses KEF’s signature Uni-Q coaxial driver array. While the LSX II LT is highly regarded for its coherent point-source imaging, the PSB iQ1 counters with a traditional, separate driver layout that some listeners prefer for its dynamic punch and treble air. Additionally, the iQ1 features a built-in MM phono stage, a key connectivity feature absent on the LSX II LT.
  • The KEF LSX II (£1199 / $1399): Competing directly with the PSB iQ2, the standard LSX II offers wireless inter-speaker connectivity and premium finish options. The iQ2 seeks to distinguish itself through its quad-amplified Class D architecture, offering a higher total power output (270W vs. KEF’s 200W) and the superior multi-room stability of the BluOS platform, which many custom integrators prefer over KEF’s proprietary Connect app.

Broader Industry Implications

The introduction of the iQ series highlights several key trends currently shaping the consumer audio industry:

  1. The Democratization of High-Resolution Audio: By packing 24-bit/192kHz DACs, DSP crossovers, and high-performance amplification into cabinets under 25 cm tall, brands like PSB are proving that high-resolution audio no longer requires dedicated, room-dominating hardware.
