Campfire Audio Solaris ‘Stellar Horizon’ In-Ear Monitors (2023) Campfire Audio

A stunning update to the Campfire classic; Solaris ‘Stellar Horizon’ features innovations and updates inside and out. With an expansive, crystalline sonic profile, Stellar Horizon presents every nuance and detail with astounding resolution, imaging, and layering. Its elegant and refined performance is mirrored externally by a re-engineered, brushed stainless steel housing with a custom gold PVD cosmic inlay, taking Solaris to a new horizon.

Stellar Horizon represents the biggest revision to the Solaris line of IEMs to date. Our new Radial Venting system elevates Solaris’ dynamic driver for a more even, accurate performance. Coupled with updated, dual-diaphragm balanced armatures, Stellar Horizon creates one of the most expansive, detailed, and resolving IEMs available. In a brushed stainless steel housing with elegant brass detailing, Stellar Horizon is a durable, striking, high-performance tool for the discerning listener.

Phase Harmony Engineering
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, 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.

Radial Venting Technology
Campfire’s exciting new technology, Radial Venting, is a revolutionary new way to house and tune our dynamic drivers. Surrounding Stellar Horizon’s 10mm DD with a ring-like chamber allows for more even pressure release on all sides of the driver’s diaphragm. This helps to create a bass response that is refined, detailed, and accurate.

Dual Diaphragm Balanced Armatures
One of the newest developments in balanced armature technology, Campfire is proud to implement Knowles’ new dual-diaphragm armatures. 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.

Tuned Acoustic Expansion Chamber – T.A.E.C.
Campfire’s patented driver treatment technology, TAEC is a specially crafted, unique space in which a balanced armature is housed. This allows for the emphasis/de-emphasis of specific frequency bands, enabling the ultra-fine tuning of a driver.
