Phase Harmony Engineering: Bringing it All Together

At Campfire Audio, our philosophy regarding driver treatment informs a considered approach that emphasizes quality over quantity. In the arms race to fit a higher and higher number of drivers into an earphone, we find that a results-driven technique for driver treatment produces superior results; with less room for pitfalls and ever-expanding variables that can undermine product consistency. 

One of the products of this approach is our Phase Harmony Engineering, which allows us to segment the frequency spectrum and assign these segments to specific drivers and allows those drivers to apply their strengths to that area. But it doesn’t end there.

By using a combination of precision-engineered driver housings and shell geometry, coupled with custom damping values, we can physically shape the tuning and response of the drivers, and further, their interaction with one another.

This driver-to-driver interaction is crucial to eliminating points of potential phase cancellation and creating the intangibles that don’t show on a frequency response curve; imaging, separation, resolution, and soundstage.

Dual Magnetic Dynamic Driver: Earth-Shaking Lows Without the Mud

Campfire Audio’s new Dual Magnet Dynamic Driver leverages an enhanced magnetic field to create greater efficiency, superior transient response, and precision diaphragm movement. This advanced audiophile transducer is characterized by a deep, emotionally resonant sound signature.

In Bonneville, the Dual-Magnet DD is implemented as a woofer, providing a rich, accurate low-end that is capable of digging deep into sub-frequencies without encroaching on the rest of the frequency range. When paired with Bonneville’s three lightning-fast balanced armatures, the Dual-Mag is free to roam the depths of the low-end and bring that crucial sense of satisfaction to your HiFi experience. 

Balancing the Profile: Bonneville’s Balanced Armatures

Campfire is proud to implement Knowles’ new dual-diaphragm armatures, one of the newest developments in balanced armature technology. This additional diaphragm allows the driver to produce greater sonic output, creating a richer signal. These drivers also feature the added benefits of lower sensitivity and extremely low harmonic distortion.

Functioning as a mid-driver in Bonneville, this driver fosters incredible performance in the extremely crucial vocal range. Bonneville will bring out every drop of emotion in your favourite vocals, riffs, and solos.

Rounding out Bonneville’s drivers are two, high-frequency dedicated, tweeter BAs. These elegantly reveal every crisp nuance of your track’s cymbal splash, snare decays, and reverb trails, with the perfect balance of sparkle and sweetness.

Solid Body Build: Safe & Sound

Campfire Audio’s patented Solid Body Design allows driver installation directly into a single, precisely 3D printed ‘engine block’ that routes the sound to the listener and uses built-in geometry to tune and accent the drivers intentionally and exactly which elevates the listening experience for the user.

Additionally, this build style improves the structural integrity within the earphone and eliminates variables and points of failure that other forms of driver routing can be susceptible to.
