Description
Campfire Audio Astrolith
Campfire Audio Astrolith is a unique dual-driver planar earphone, it delivers an ultra-full-range stunning performance at a realistic price.
With a dual planar magnetic driver configuration and utilising two all-new planar drivers, the Campfire Audio Astrolith is the vanguard of planar IEM performance. Wrapped in a semi-transparent, lightweight, 3D-printed acrylic body, and a robust, mirror-finished, stainless steel face-plate, Astrolith is versatile and striking in both appearance and performance.
The latest from the acoustics team at Campfire Audio, Astrolith represents the next step for Campfire’s line of pure planar magnetic IEMs. Astrolith incorporates two new drivers wrapped in our PPR and AAOI tuning elements. Combining the inherent advantages of planar magnetic drivers with decades of acoustic engineering experience brings about an incredible new horizon in the realm of planar magnetic IEMs.
6mm Planar + PPR
With Astrolith, we are excited to reveal our first implementation of our 6mm planar magnetic driver, which is paired with our new Particle Phase Resonator (PPR) tuning chamber to bring truly astounding high-end performance. This driver is very atypical relative to other planar drivers due to its very small size.
Larger planar drivers already move incredibly fast, so shrinking the form down and focusing the response to the high frequencies, creates lightning fast transient response and upper range detail.
14mm Planar + AAOI
Filling out the body of Astrolith’s tuning, is an updated generation of our 14mm planar magnetic driver. First seen in our renowned IEM, Supermoon, this updated version features refined mechanics and updated grille patterning.
The raw strengths of this driver have been carefully and precisely shaped by our new Additive Acoustic Optical Inclusion (AAOI) housing to hone the impact, texture, imaging, and layering ranging from the sub-bass to the midrange and gracefully blending with the upper registers powered by its companion, 6mm driver.
AAOI Housing
Campfire is proud to introduce our new Additive Acoustic Optical Inclusion housing (AAOI). This shell offers unique contributions in both performance and style. With built-in acoustic-shaping geometries, our AAOI housing contributes to the refinement and enhancement of the output of Astrolith’s dual planar magnetic drivers. These chambers are carefully engineered to create precisely controlled acoustic volumes and ensure the targeted vision for Astrolith’s sonic performance.
In style, Astrolith’s shell is truly unique with the addition of its optically inclusive internal chambers within a transparent exterior. This creates a unique, gem-like effect, allowing for a changing perspective and internal visibility from various angles, appearing sleek and black at a distance, but revealing light and structure from within.
Particle Phase Resonator – PPR
Specially designed to couple with and enhance the performance of Astrolith’s new and unique 6mm planar driver, Campfire’s Particle Phase Resonator is one of our smallest and most precisely engineered driver housings to date. Shaping this driver’s performance was an incredible challenge from an engineering standpoint; the size and speed of this driver called for incredibly low tolerances and delicate treatment.
Campfire’s PPR smooths and tempers the 6mm driver while still allowing it to shine and do what it does best: create lightning fast transients, resolution, and top-end detail.
Advancing Pure Planar Performance
Until recently, planar drivers were deemed unsuited for IEM applications; held back by size, sensitivity and cost limitations, they were long used in over-ear headphones. However, advancements in this technology have overcome these limitations enough for them to be used in portable, in-ear applications.
Now, the wonderful character and advantages of planar drivers can be brought to IEM lovers; with their unique blend of size and speed and accompanying unique sonic characteristics.
Campfire’s first planar IEM, Supermoon’s premium, planar sound quickly became a fan favorite and became one of the most renowned planar IEMs on the market. Moon Rover set a new standard for linearity and balance in Campfire’s lineup. Now, Astrolith is the modern torch-bearer of Campfire’s planar evolution.
