Introducing the Harmony XR Ultra

Precision Redefined. Resolution Unleashed.

We are proud to introduce the Harmony XR Ultra, the evolved expression of our acclaimed Harmony XR bookshelf speaker. Redesigned with a high-resolution ribbon tweeter and a newly retuned crossover network, the XR Ultra delivers a level of openness, detail, and refinement that takes the Harmony series to a new sonic benchmark.

Built on the strong foundation of the original XR, the Ultra version pushes resolution further—extending high-frequency performance beyond 40 kHz, enhancing transient speed, and revealing micro-details that conventional dome tweeters simply cannot reproduce.

The Philosophy Behind Harmony XR Ultra

In high-end audio, true progress comes not from change for the sake of change, but from meaningful refinement. The Harmony XR Ultra was developed from a deep passion for accurate sound reproduction and an obsession with balance—technical precision paired with musical emotion.

Inspired by the design philosophy of legendary audiophile loudspeakers and refined through extensive listening and measurement, the XR Ultra represents our commitment to clarity, coherence, and realism. Every upgrade—from the tweeter to the crossover—was implemented to serve the music, not the spec sheet.

The Design

The Harmony XR Ultra retains the proven cabinet architecture of the XR while refining its acoustic behavior. It features a rigid, resonance-controlled enclosure with reinforced internal bracing and a double-layer 18mm MDF front baffle. This construction minimizes cabinet coloration and provides a solid foundation for the upgraded driver system.

The larger, ported enclosure is carefully tuned to enhance bass extension and control, allowing the speaker to deliver authority in the low end while maintaining clarity across the spectrum. The result is a bookshelf speaker that sounds far bigger than its size suggests.

The Mid-Bass Driver

At the core of the Harmony XR Ultra is our carefully selected Egyptian papyrus cone mid-bass driver. Lightweight yet rigid, this paper-based cone preserves the natural tonality and warmth audiophiles love, while offering excellent transient response and control.

Its high sensitivity and smooth frequency response ensure a rich, expressive midrange, powerful mid-bass punch, and seamless integration with the ribbon tweeter above. Vocals sound lifelike, instruments retain their natural timbre, and bass remains tight, articulate, and engaging.

The Ribbon Tweeter – Ultra High Resolution

The defining upgrade of the Harmony XR Ultra is its hi-resolution ribbon tweeter.

Unlike traditional dome tweeters, ribbon tweeters excel at speed, detail, and air. The ultra-low moving mass allows the XR Ultra to reproduce high frequencies with astonishing precision and effortlessness, extending well beyond 40 kHz.

This results in:

• Exceptional clarity and micro-detail

• A wider, more open soundstage

• Faster transient response

• Smooth, fatigue-free highs

Cymbals shimmer naturally, ambient details emerge effortlessly, and spatial cues are rendered with stunning realism.

The Retuned Crossover – Perfect Integration

To fully unlock the potential of the ribbon tweeter, the Harmony XR Ultra features a newly redesigned crossover network.

The crossover point has been raised to 3.5 kHz, allowing the ribbon tweeter to operate comfortably within its optimal range while preserving midrange purity and coherence. Utilizing a 3rd-order 18 dB/octave slope, the crossover ensures precise driver handoff, phase accuracy, and seamless integration.

This careful retuning results in:

• Improved tonal balance

• Enhanced clarity in the upper midrange and highs

• A more natural and cohesive presentation

The XR Ultra doesn’t just sound more detailed—it sounds more correct.

The Lows – Powerful Without a Subwoofer

Despite its bookshelf form factor, the Harmony XR Ultra delivers deep, authoritative bass that surprises listeners. The synergy between the cabinet volume, port tuning, and mid-bass driver allows the speaker to reproduce low frequencies with weight and control.

From the impact of a kick drum to the texture of bass guitars, the XR Ultra handles low-end content with confidence. When paired with a capable amplifier, many listeners will find that a subwoofer is simply unnecessary for music playback.

The Highs – Air, Space, and Emotion

The ribbon tweeter elevates the high-frequency performance to a new level. Highs are open, airy, and incredibly detailed, yet smooth enough for long listening sessions. There is no harshness, no artificial brightness—only clean, extended treble that enhances realism and immersion.

Whether it’s delicate vocal overtones or complex orchestral textures, the XR Ultra presents highs with finesse and control, completing a truly balanced sonic signature.

The Finish

Designed to complement both modern and classic interiors, the Harmony XR Ultra features a sleek, rugged finish that is as durable as it is elegant. The surface is easy to maintain and built to withstand years of use while retaining its premium appearance.

Experience the Harmony XR Ultra

The Harmony XR Ultra is not just an upgrade—it’s a refinement of everything the Harmony XR stood for. With its hi-res ribbon tweeter, retuned crossover at 3.5 kHz, and carefully balanced acoustic design, it delivers a listening experience that is more detailed, more open, and more emotionally engaging than ever before.

Hear what ordinary speakers can’t.
Welcome to the next level of Harmony.
