LIGNUM Series

Professional high power loudspeakers & passive subwoofers

Built in birch plywood with a polyurea finish, the LIGNUM Series delivers maximum sound pressure, precise coverage and clean aesthetics — engineered for fixed installations that refuse to compromise on either performance or appearance.

The challenge in fixed installations

Two problems that conventional speakers can’t solve

– restaurants – hotels – auditoriums – conference rooms – gyms – retail – education – and more –

The context

Acoustically complex spaces

Crowded restaurants, gymnasiums with demanding music, shopping malls with long reverberation times — these environments expose every weakness in coverage and clarity that underpowered speakers have.

The aspiration

Aesthetic limitation

Architects and designers work with concepts where visual cleanliness and total integration are essential. Most high-power speakers are built for performance, not for spaces people care about how they look.

The LIGNUM Series was created to solve this duality: maximum acoustic performance, with a compact and elegant design in wood and polyurea finish — at a more affordable price than premium brands, and far superior in quality to economy or ABS options.

LIGNUM for difficult spaces

Acoustic performance

Performance that makes the difference

Four engineering advantages that set the LIGNUM Series apart from conventional fixed-install speakers.

01
Efficiency · Sensitivity
High Sensitivity
High sensitivity

Sensitivity values range from approximately 90 dB to 101 dB (1 W/1 m) depending on model — allowing higher SPL with less electrical power applied compared to conventional systems in this category.

  • Use more modest power amplifiers — reducing overall system cost
  • Lower energy consumption for the installation
  • Clear and balanced reproduction even at low volume levels
02
Output · Coverage
High Maximum SPL
Maximum SPL

Maximum SPL values range from approximately 108 dB to 126 dB — ideal for gyms, sports centres and high-volume venues, providing wider coverage with fewer units.

  • Coaxial models (4″–6″): compact design with near-field clarity
  • Subwoofer systems (8″ and 12″): deep bass reinforcement and maximum impact
  • SPL scales proportionally with loudspeaker size and configuration
03
Clarity · Fidelity
Low Distortion (THD+N)
Low distortion

Average THD remains below 1% in mid and high frequencies at rated conditions — comparable to reference systems in its category. Optimised driver design reduces structural resonances and nonlinearities.

  • Improved speech intelligibility across the entire spectrum
  • Clean and defined reproduction, especially in mid and high frequencies
  • Less listening fatigue in continuous-use installations
04
Dynamics · Headroom
Good Level of Headroom
Headroom

Enclosure design maintains adequate dynamic range — avoiding audible compression and distortion even with transient peaks from vocals, percussion or effects.

  • More natural and controlled reproduction
  • Greater long-term system stability in continuous-use applications
  • No audible compression at rated operating conditions

Frequently asked questions

The series includes LIGNUM-4 (4″ coaxial, 60W), LIGNUM-6 (6″ coaxial, 120W), LIGNUM-8SUB (8″ subwoofer, 250W) and LIGNUM-12SUB (12″ subwoofer, 400W). The LIGNUM-BR-L full-motion wall bracket is also available.
Birch plywood offers less resonance and better acoustic response than ABS plastic. Combined with the polyurea finish, it provides greater durability against humidity, shock and temperature — and a more refined aesthetic that integrates naturally with designed interior spaces.
Yes, both the LIGNUM-8SUB and LIGNUM-12SUB are passive subwoofers, requiring an external power amplifier. This gives installers full flexibility over amplification choice and system design.
Match your amplifier to the RMS rating of the speaker: 60W for LIGNUM-4, 120W for LIGNUM-6, 250W for LIGNUM-8SUB and 400W for LIGNUM-12SUB. The high sensitivity means you can achieve high SPL with relatively modest amplifier power.
Yes. The LIGNUM Series is designed so the full-range coaxials and passive subwoofers work together as a complete system, from compact near-field installations to larger full-range systems with bass extension.
Polyurea is a spray-applied protective coating offering excellent resistance to abrasion, scratches, moisture and temperature extremes. It gives the LIGNUM Series its distinctive textured surface while protecting the birch plywood enclosure for long-term durability.
The LIGNUM-BR-L full-motion wall bracket is compatible with the LIGNUM Series loudspeakers, providing full tilt and swivel adjustment for precise aiming and clean professional installation.
