Embark on an epic sonic odyssey with Bonneville. A fusion of cutting-edge tech and artistry, Bonneville guides you through a symphonic voyage. Its hybrid design, including a 10mm Dynamic Driver and Custom BA for mids, alongside dual balanced armatures for highs, crafts a soundscape that paints each note with precision.
This model is inspired by the popular Campfire Solaris hybrid lineage, adapted to a custom fit version for the first time with an evolved presentation and new driver innovations. Wrapped in a crafted solid body, Bonneville invites you to unravel sound's layers, charting musical horizons.
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 to 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, that 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 are able to 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.
Custom 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.
Each custom fit in-ear monitor begins with an ear impression. This impression is scanned into our system. Through our signature process, we manipulate the interior acoustic chambers of the Bonneville design; arranging them in optimal position inside the shape of the impression. This also allows us the opportunity to optimize the performance of the IEM for your ear, resulting in a better-sounding IEM.
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.
