Overview
Ponderosa
Immerse yourself in unparalleled sound precision with Ponderosa’s five custom balanced armatures, each meticulously optimized for audio clarity. Encased in a masterfully crafted solid body and finished with sophisticated accents, Ponderosa transforms every note into a captivating portrait, painting the music in its truest form.
This model is inspired by the legendary Campfire Andromeda, but at a more accessible price point, and with a new mid-driver. Compared to the previous Solstice model, you'll enjoy improvements to soundstage and phasing.
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.
Expansive Sound With Patented T.A.E.C.
Beyond Frequency Response
Campfire’s patented driver treatment technology — our Tuned Acoustic Expansion Chamber — is a specially crafted, unique space in which a balanced armature is housed. This allows for the emphasis and de-emphasis of specific frequency bands, enabling the ultra-fine tuning of a driver.
In Ponderosa, TAEC is applied to the dual-high driver assembly to create an incredibly precise and detailed high-frequency response. Coupling this high driver architecture with our three-way Phase Harmony Engineering ensures a smooth interaction between a segmented, precision-tuned high-end and the remaining frequency range.
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 Ponderosa 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.
Audiophile & Artist Fits
Whether you're listening at home, flying coast to coast, or performing on stage, you'll get a great fit bespoke to your ears — no eartips needed. Campfire offers two custom fit style options to fit everyone's needs.
Pick a Colour
Choose a bold green colourway, or pick classic black for a stealthy look. Every earphone features our 3D-printed housing matched with a stainless steel faceplate and spout.
Pick a Package
Ponderosa Custom includes a complement of accessories in your choice of green or black.
Time Stream Cable
Ponderosa features our new Time Stream Chromatic Series cables. Specifically designed for audio aficionados, each cable is crafted with enamelled silver-plated copper conductors and a non-migratory PVC jacket for enhanced durability. Equipped with custom-made MMCX connectors of copper and beryllium, these cables promise a longer lifespan. With 2.5mm, 3.5mm, and 4.4mm termination options all available, you’ll be sure always to have what you need to keep Ponderosa the earphone of choice with all of your audio devices, including those that benefit from balanced output.
