Sound & Colour
For the ZIM LTD Collection, Tufnel became a canvas for colour, texture and material. Working directly with Zimmermann, colour development saw each finish carefully adapted across timber,
metals and resin, giving the collection a character entirely its own.
Celebrating the sound of summer
The ZIM LTD Collection is a collaboration between Zimmermann and Atlas Harmonic.
Created for a series of events along the French Riveria, the collection translates the colours of summer into a limited edition of ten loudspeakers.
Designed to be Heard
The ZIM LTD is built upon Atlas Harmonic's flagship Tufnel platform, a loudspeaker developed to reproduce music in its most grand form.
Designed for larger living spaces and open-plan environments, it creates a listening experience that feels effortless, immersive and deeply engaging.
Three limited colours.

Frequently asked questions
The SK96 horn is designed to maintain wide, even dispersion across the listening area. Its geometry is based on an oblate spheroidal expansion, refined to keep off-axis response smooth and predictable. This allows the system to maintain tonal balance and clarity beyond a single listening position.

The Tufnel is designed to operate as a true full-range loudspeaker in open, architectural environments. High efficiency, controlled dispersion, and cabinet volume allow consistent sound across the room, rather than a single listening position.
A Full-Range System for Larger Spaces
Pricing starts at $20,300 AUD per pair. Production time is 8-12 weeks depending on finish. Each system is built to order. For commissioning enquiries, please submit your details and we will respond personally. Custom finishes and detailing are available to suit the character of the space. International shipping is available.

DESIGN INTENT
In the 1960s and 70s, speakers were physically large and designed to move air easily. They produced sound with scale and dynamics that smaller systems struggle to reproduce.
Tufnel set out to bring that sense of scale back into a modern loudspeaker. At the same time, it retains the precision expected from contemporary hi-fi.
The result sits between two worlds:
The energy of a club system, and the refinement of a high-fidelity setup.

The massive 15-inch woofe
r is engineered for high efficiency and exten
ded bass output, delivering a big, full sound with lifelike dynamics.
High Frequency Transducer
1.4inch compression driver coupled to our proprietary horn. Its geometry promotes controlled directivity and smooth dispersion.
Leather
Finished in full-grain leather, the front panel adds durability and softens the visual presence of the cabinet.
Stand
Fabricated from aluminium, providing a rigid foundation and correct listening height.
Low Frequency Transducer
A high-efficiency 15-inch woofer provides extended low-frequency output with minimal distortion, delivering scale and impact without loss of control.
Cabinet
Crafted from solid timber and high-density composite, the enclosure is heavily braced to control resonance and provide a stable acoustic platform.
SYSTEM SUMMARY
A FULL-RANGE SYSTEM FOR LARGER SPACES
The Tufnel is designed to operate as a true full-range loudspeaker in open, architectural environments.
High efficiency, controlled dispersion, and cabinet volume allow consistent sound across the room, rather than a single listening position.
DESIGN & MATERIALS
The cabinet is built as a rigid, structural enclosure rather than a lightweight shell.
Solid timber and leather are selected for acoustic performance, durability, and how they wear over time.
Each system is finished by hand, with materials chosen to suit the space it will live in.
SK96 HORN
The SK96 horn is designed to maintain wide, even dispersion across the listening area.
Its geometry is based on an oblate spheroidal expansion, refined to keep off-axis response smooth and predictable.
This allows the system to maintain tonal balance and clarity beyond a single listening position.
15" Low-Frequency Driver
A 15-inch driver provides high displacement with low distortion.
The larger radiating area allows the system to produce bass with weight and headroom, even at lower listening levels.
GRILLE
Removable grille designed to remain acoustically transparent.
AVAILABLE CONFIGURATIONS
Tufnel is available in both active and passive configurations.
Passive
Designed for use with external amplification, including low-powered tube systems.
Active
Integrated amplification and DSP provide crossover control, time alignment, and system protection.
BESPOKE FINISHES
Each system is built to order with selected timbers, leathers, and custom finishes.
Materials are chosen in response to the space.
Integrated Electronics
The active system integrates amplification and DSP within the cabinet.
Each driver is powered and controlled independently, allowing precise crossover control, time alignment, and system protection.
Analog and digital inputs allow integration into a wide range of systems.
A passive version is also available for use with external amplification.
Specifications
Transducers
15-inch low-frequency driver with proprietary paper-fiber diaphragm and 3-inch voice coil for high output and low distortion.
1.4-inch compression driver with titanium diaphragm and neodymium motor for dynamic, high-efficiency high-frequency reproduction.
SK96 Horn
360 mm constant-directivity horn with 36 mm throat, engineered for smooth in-room response and controlled dispersion across a wide listening area.
Passive Version
Fully analogue crossover with fourth-order acoustic slopes and resonant compensation networks for precise driver integration. 8-ohm nominal, 800 watt peak power and 400 watt continuous power handling.
Active Version
Integrated Hypex Ncore amplification with advanced digital signal processing. Capped at 800 watt peak power.
Balanced XLR, RCA, and digital inputs (AES, S/PDIF, Optical).
Time alignment, protection, and optimized crossover processing built in.
Selectable sound profiles available.
HANDMADE IN AUSTRALIA
Each system is built to order in Sydney by a small team of craftsmen. Production is intentionally limited to maintain consistency and quality. Speakers are assembled in matched pairs and individually finished.
