    Phase Harmony Engineering: Bringing it All Together

    At Campfire Audio, our philosophy regarding driver treatment informs a considered approach that emphasizes quality over quantity.

    One of the products of this approach is our Phase Harmony Engineering, that allows us to segment the frequency spectrum and assign these segments to specific drivers. Applying precision housing geometry and custom damping values enable us to physically shape the tuning and response of your earphones.

    This approach lends itself to improving 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 favorite 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 in an intentional and exact manner that elevates the listening experience for the user.

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

    • "[Bonneville] combines fantastic bass response with excellent control, creamy musical mids with nice timbre, and extended, articulated treble which is never fatiguing. The overall technical performance is also noteworthy, with a well-executed staging performance in particular."
