Credo EV 350 Ref. – Precision. Emotion. Perfection.

Swiss-crafted for those who hear the difference.

True sound doesn’t come from size—it comes from precision. Many compact speakers force compromises, losing depth, presence, and realism. The Credo EV 350 Ref. was designed to challenge that perception.

Handcrafted in Switzerland, this speaker brings together decades of engineering expertise, cutting-edge materials, and an uncompromising passion for music. Designed for those who demand absolute purity in sound, the EV 350 Ref. is not just a smaller speaker—it is a high-performance instrument that reveals the full depth of your music.

With a soundstage that extends far beyond its physical dimensions, deep, controlled bass, and effortless clarity, the EV 350 Ref. creates a listening experience that is both intimate and expansive.

The EV 350 Ref. – A Masterpiece of Balance and Clarity

The EV 350 Ref. is an achievement in engineering restraint and precision—a speaker designed to do exactly what it should: reveal every detail of the music, without adding or subtracting anything.

It is compact, but not limited. Capable of delivering deep, controlled bass, stunningly coherent midrange, and effortless high-frequency extension, the EV 350 Ref. was designed for those who expect the very best from a speaker, regardless of size.

Key Features

  • Custom ScanSpeak Drivers – The 5.5” mid-woofer uses a sliced-paper cone to control resonance and maintain absolute clarity in the midrange and bass.
  • Time-Aligned Crossover Network – Designed to push phase shifts outside the crossover spectrum, ensuring a seamless transition between drivers.
  • Resonance-Controlled Cabinet – Precision-machined and internally damped for maximum neutrality—what you hear is the music, not the speaker.
  • Expansive Soundstage – The EV 350 Ref. delivers a holographic listening experience, with pinpoint imaging and a wide, immersive presentation.

This is a true reference speaker, offering the purity, accuracy, and musicality that define the Credo sound.

The Designer: Michael Kraske – The Pursuit of Sonic Perfection

At the core of every Credo speaker is the vision of Michael Kraske, a speaker designer and system engineer whose work has been praised by many experienced and respected industry experts. Kraske believes that a loudspeaker should not impose itself on the music—but should disappear, leaving only the artist’s intent. His designs, rooted in scientific research and refined through thousands of hours of listening, have been recognized by:

Marc Phillips (Part-Time Audiophile)
“A truly reference-class bookshelf speaker with killer imaging and deep layers of detail.”

Michael Lavorgna (Twittering Machines)
“An exceptionally clean-sounding speaker, as if music pours through it untouched and uncolored.”

Ken Micallef (Stereophile)
“Seamless, immense in scale, truly immersive.”

With an extensive background in high-end speaker development and monitoring applications, Kraske’s work ensures that every Credo speaker faithfully translates the emotional and dynamic nuances of a live performance.

Credo Audio EV Reference ONE award

I really tried to push the Credos and find out their fatal flaw. They didn’t wimp out during a handful of Tool/System of a Down listening sessions by hardening up in the treble or breaking up in the low frequencies, although I tend not to listen at eviction-prompting levels. These speakers kept up with me and did everything I wanted them to do. I can’t think of one time where I wanted something different to happen to my music.

Instead, I tend to place the emphasis on whether I would buy a particular hi-fi component for myself. If I was at a high-end audio store, listening to a product, would I pull out the credit card? The list of those products, for me, is a far shorter one, and the Credo EV 350 Reference qualifies. To paraphrase an old audio buddy, if someone handed me a pair of the EV 350s and told me those were the only speakers I could ever listen to for the rest of my life I’d say okay, thanks!

Credo Audio – A Tradition of Swiss Excellence

Credo Audio loudspeakers are more than high-end audio products—they are expressions of Swiss precision, uncompromising quality, and innovation. Many key components, such as mechanical parts and crossovers, are designed and assembled in Switzerland, while other critical elements are sourced from renowned manufacturers in Denmark, Germany, and the Netherlands.

  • Swiss precision engineering – Every speaker is assembled in-house with meticulous attention to detail.
  • Premium materials – Cabinets constructed from high-density European fiberboard (HDF and MDF), chosen for both acoustic performance and sustainability.
  • Designed for music lovers – Not built to fit a price point, but to achieve perfect transparency in real listening environments.

At Credo, we are not interested in following trends—we are committed to creating loudspeakers that set new standards in transparency, accuracy, and long-term musical enjoyment.

The Science Behind the Emotion

Every Credo speaker is meticulously engineered to be an honest and revealing musical instrument. While the listening experience is purely emotional, the technology behind it is grounded in acoustic precision and innovation.

  • Optimized Timing & Phase Response – The crossover network is designed to push phase shifts beyond the audible crossover spectrum, maintaining coherence and imaging accuracy.
  • Smooth Frequency & Impedance Response – A linear, stable load ensures compatibility with a wide range of amplifiers, preserving dynamics and transparency.
  • Controlled Bass Performance – Advanced bass-reflex tuning extends low-frequency depth without overhang, delivering tight, powerful bass without artificial boost.
