Welcome

These hifi brands are among those best known for making field coil speakers.

A field coil driver in a speaker uses an electromagnet instead of a permanent magnet to generate the magnetic field, allowing for greater control over flux density and improved dynamic response. This design is desirable because it can deliver lower distortion, higher efficiency, and a more natural, detailed sound compared to traditional permanent magnet drivers.

Treehaus Audiolab builds speakers using vintage Klangfilm-era field coil drivers that are rebuilt by Atelier Rullit, housed in open baffles made from live-edge wood slabs that both look striking and help diffuse sound. Their speakers are highly efficient (over 100 dB/1m) and work especially well with low-power SET tube amplifiers, while incorporating DSP for precise room correction in the low frequencies.

Learn about the brand

  • They distinguish themselves by hand-crafting nearly every component of their wideband drivers in-house, allowing for complete control over design and materials, including specialized paper diaphragms and unique motor designs.
  • The brand's speakers often feature back-loaded horn designs and proprietary Acoustic Stealth Technology (AST) to optimize bass response and manage internal resonances without traditional crossovers.
  • Voxativ creates complete audio systems, including amplifiers and cables, designed to synergize with their wideband drivers, ensuring optimal performance and a cohesive sonic signature.

Our interview with the brand

What are two key technological innovations or strong opinions that differ you from other brands?

At Voxativ, we follow the philosophy of absolute signal purity – this is why we design and build our own wideband drivers entirely in Berlin, without any crossover components in the signal path. One key innovation is our patented Acoustic Stealth Technology, which allows the drivers to produce full-range sound with stunning resolution and dynamics, all from a single voice coil.

Secondly, we believe in the synergy of engineering and craftsmanship: all our cabinets are handmade with precision joinery and fine veneers, acting as musical instruments rather than mere housings. This holistic approach results in a level of emotional engagement that we believe is quite rare in high-end audio.

What's your approach to customer support?

We always encourage customers to contact their local dealer or distributor first – they are part of the Voxativ family and trained to assist with all typical needs. However, if a customer prefers, or if the issue is more specialized, they are always welcome to contact us directly.

We pride ourselves on building long-lasting relationships with our clients, and that includes aftercare. Whether it's helping a customer reconfigure their system, adjust positioning, or even upgrade older components, we're always just a phone call or email away. We've even flown across the globe to personally install or fine-tune systems – because music, like friendship, deserves personal attention.

What are your favorite tracks for showcasing the strength of your products?

Keith Jarrett – Köln Concert (Part I): This piece shows how naturally and intimately our systems reproduce piano timbre and room acoustics.

Youn Sun Nah – My Favorite Things: Her voice, full of subtlety and nuance, is a great test of transparency and realism.

Yello – The Race: Dynamic, detailed, and rhythmically complex – a thrilling way to show off bass precision and soundstage layering.
