• Speaker Type: Three-way, bi-amp, Hybrid® horn-loaded, trapezoidal: The 3-way bi-amp structure separates the bass, mid, and treble ranges to optimize the sound phase, providing accurate, clear, and stable sound across all frequency ranges. Martin Audio's exclusive Hybrid® horn-loaded design increases the efficiency of acoustic energy conversion, creating strong sound pressure with low harmonic distortion, for a sound that is both powerful and smooth.
• Frequency response range: 50Hz – 18kHz ±3dB: This wide frequency range allows Martin Audio THH to reproduce sound from deep bass to detailed treble, providing a realistic and natural experience. The ±3dB error level represents a stable response, giving a balanced tone, without deviation when operating in different frequency ranges.
• Dispersion (-6dB): 70° horizontal × 40° vertical: This coverage angle helps the sound spread evenly, suitable for medium and large halls and stages. The precisely directional horn system reduces off-axis reflections, improves vocal clarity, and delivers focused and sharp sound even at long distances.
• Rated Power: LF 750W AES / 3000W Peak – MF+HF 300W AES / 1200W Peak: With a total peak power of up to 4200W, the speaker operates powerfully and stably even in high-intensity performance environments. AES (Audio Engineering Society) measurement standards ensure real power, reflecting real durability and performance in continuous operation.
• Rated impedance: LF 8 Ohm – MF+HF 8 Ohm: Standard impedance level makes it easy for Martin Audio THH to be paired with many professional power amps such as Lab.Gruppen, Powersoft or Martin Audio amplifier, ensuring stable signal and optimal amplification performance.
• Sound Pressure Level (SPL): Continuous 133dB, peak 139dB. This is an extremely impressive parameter, demonstrating the ability to create strong sound pressure while maintaining clarity. With a peak SPL of 139dB, the speaker can cover clear sound in a large space without distortion, meeting the sound needs of outdoor stages or large-scale events.
• Drivers: Bass 15 inch (4 inch voice coil), Mid 10 inch (2.5 inch voice coil), Treble 1 inch (Kapton diaphragm): The scientifically arranged driver system helps the sound to be coherent and clearly separated. The Kapton membrane of the HF driver has good heat resistance, high sensitivity, giving bright, smooth and durable treble when operating continuously.
• Dimensions: 1067mm × 558mm × 780mm – Weight: 77.5kg: The carefully calculated speaker cabinet ratio helps to optimize resonance efficiency, reduce noise and easy to arrange in the main or auxiliary speaker system. The large weight shows that the speaker cabinet has a solid structure, thick walls, ensuring high mechanical stability when operating at high power levels.
• Shell material: Multi-layer birch plywood with scratch-resistant paint coating: This material is renowned in the professional touring speaker industry, providing natural sound, high mechanical strength, good moisture and vibration resistance — an important factor that helps Martin Audio THH operate durably in many harsh stage conditions.

Outstanding features of Martin Audio THH Speakers

Martin Audio THH speakers are a line of professional performance speakers developed by Martin Audio (UK) based on the philosophy of "Sound Reinforcement with Precision and Power" - delivering precise, powerful and emotional sound. Not only outstanding in technical design, THH also demonstrates top performance ability thanks to the combination of technology, structure and high-quality materials.

• Three-way structure optimizes sound mixing: Martin Audio THH has a 3-way bi-amp configuration, independently separating the three frequency ranges (Low – Mid – High). Thanks to that, the speaker reproduces detailed, accurate and faithful sound, especially in the mid-range – where the clarity of the vocals is determined. This structure helps limit phase distortion, giving a “seamless” sound quality between frequency ranges – something that two-way speakers find difficult to achieve.
• Exclusive horn-loaded Hybrid® technology: THH uses a Hybrid® horn-loaded structure – a combination of horn loading and bass reflex resonance chamber, for high performance while maintaining natural timbre. Thanks to the principle of sound pressure compression and even dispersion, the speaker achieves SPL 133–139dB without distortion. This is the strength that creates the Martin Audio brand, helping THH operate stably even in conditions of continuous touring and performance.
• Powerful performance – outstanding durability: With a total peak power of 4200W, the speaker can easily handle large shows and halls with hundreds of guests. The large diameter voice coil (4 inch LF, 2.5 inch MF) is heat-resistant and maintains high performance during long-term operation. The multi-layer birch wood speaker cabinet increases rigidity, reduces vibration, and makes the sound tight, stable, and natural.
• Precise sound coverage, good directional control: Scientifically designed 70° horizontal x 40° vertical coverage angle helps sound spread evenly throughout the space. High frequency (HF) directional waveguide system controls off-axis reflection well, providing a clear and sharp sound field at every seating position.
• Optimal combination & flexible installation: Perfectly compatible with Martin Audio DSP amplifiers, or high-end amplifiers such as Lab.Gruppen, Powersoft. Can be used as a line array, single or stacked with subwoofers depending on the stage configuration. The horizontal trapezoidal design helps reduce standing wave resonance, and is easy to arrange when installing multiple speakers side by side.
• Touring design – maximum protection: The Polyurethane coating is scratch-resistant, moisture-proof, and shock-proof, meeting touring standards. The thick, powder-coated steel mesh protects the speaker from impact and dirt during transportation and performance. The weight of 77.5 kg shows its "solidity", solidity, and carefully reinforced structure for long life.

Detailed review of Martin Audio THH Speakers

Sound quality and frequency reproduction

Martin Audio THH delivers accurate and faithful sound across the entire frequency range of 50Hz – 18kHz. Thanks to the independent three-way design, each speaker has a clear role: 15-inch bass for deep and tight bass, 10-inch mid-range reproduces clear mid-range, and 1-inch treble with Kapton membrane for smooth and bright highs.

The ±3dB frequency response ensures a balanced dynamic range, allowing vocals, instruments and stage effects to be presented naturally. When operating at 133–139dB SPL, the speaker maintains low distortion thanks to the Hybrid horn-loaded mechanism that increases sound pressure and optimizes the direction of sound.

The overall sound that Martin Audio THH delivers is powerful, detailed and deep — something that makes Martin Audio stand out in professional performances.

Engineering design and durability

Mechanically, the Martin Audio THH is designed with a horizontal trapezoidal body, optimized for coupling or hanging clusters in line-array PA systems.
