Discover the standout specs and design choices of the Bonneville Multiverse III Achromatic Series, a limited hybrid IEM from Campfire Audio.
Quick Answer
The Campfire Audio Bonneville Multiverse III is a limited hybrid IEM (25 units) that pairs a new dual-magnet dynamic driver with three balanced armatures for energetic, musical sound with high resolution.
Why the Bonneville Is a Special Edition
With only 25 units produced, the Bonneville Multiverse III Achromatic Series is one of Campfire Audio's most exclusive releases. This limited run means each pair is collectible, but also that once sold out, replacements or spare parts may be harder to source than for standard models.
Hybrid Driver Architecture
The Bonneville uses a 10mm dual-magnet dynamic driver for the low end, paired with three balanced armatures (one mid, two high) for mids and treble. This hybrid approach aims to combine dynamic driver punch and airiness with BA clarity and detail, though the crossover tuning is unique to this model.
