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.

  • "Technically, Solaris Stellar Horizon is on a whole different level to the previous models with a much-improved soundstage performance, additional headroom, and generally a more coherent presentation.

    If you are coming from the OG Solaris, the openness of the mids and the wider staging quality is perhaps the most striking difference. These new drivers and acoustical chamber designs really cast out a very wide stereo field in keeping with what a lot of flagship monitors seem to be going for"

  • "... when I tried Tove Lo and her fantastic “How Long”, the Solaris Stellar Horizon simply turned into an astonishing show. The forwardness, detail, and timbre of her voice were just absolutely marvelous, and I actually went on to listen to the track three times in a row. Additionally, what I’m going to spoil for you is the soundstage which is absolutely up there with the best of the best on the market, which further enhances the midrange performance, especially with female vocals."

  • "The Campfire Audio Solaris Stellar Horizon offers a sound tuning that impressed me with its balanced, natural and quite accurate tuning and timbre. The bass is deep, powerful and well-controlled, with excellent extension, speed and authority especially after a burn-in period of 100+ hours. The midrange sounds pretty rich, smooth and detailed, with a clear and transparent presentation of vocals and instruments, while the treble area is produced in a pretty crisp, airy and extended manner, which shows a smooth and refined delivery of nuances and subtleties. The soundstage on the other hand is wide, spacious and fairly immersive that delivers a realistic and holographic sound field."

  • "With the Solaris Stellar Horizon, Campfire Audio has made a perfect tune-up of their beloved Solaris series by introducing next-level performance, clear solid bass, and seducing upper-frequencies... making it recommendable as an endgame choice for those who would like to have a neutral-bright sound that is highly resolving yet also refined and smooth."
