Martin Audio THH – 15" Horizontal Horn-Loaded Three-Way Loudspeaker

Product Overview

The Martin Audio TH Series THH is a very high performance, fully horn-loaded, three-way loudspeaker engineered for large-scale live sound reinforcement and permanent installation applications where maximum SPL, controlled dispersion, and sonic clarity are required from a single enclosure. Built in a horizontal trapezoid format, the THH employs Martin Audio's Hybrid LF loading technology alongside a phase-ball loaded mid-driver and high-frequency horn, delivering wide-bandwidth performance across the full audio spectrum. The THH is the preferred choice of touring sound engineers and AV system designers specifying large club, theater, or outdoor stage systems where conventional direct-radiating cabinets fall short of the output and projection requirements. It is available from Creation Networks alongside the full Martin Audio product range.

Product Description

The TH Series represents Martin Audio's high-efficiency, horn-loaded touring and installation loudspeaker platform. The THH is the horizontal-format model in this series, designed for applications where a wide horizontal coverage pattern is required from a single cabinet — common in wide-stage theatrical applications, large club main PA positions, and permanent installations in wide-format auditoriums.

All three frequency bands in the THH are horn-loaded, a design approach that maximizes acoustic efficiency and enables the cabinet to achieve very high SPL from a given amplifier power budget compared to direct-radiating or bass-reflex designs. The low-frequency section employs Martin Audio's proprietary Hybrid loading — a combination of horn loading and reflex tuning that extends usable low-frequency bandwidth while maintaining the high efficiency characteristic of a fully horn-loaded design. The mid-frequency driver is loaded through a phase-ball coupler into a dedicated mid horn, providing smooth, high-efficiency reproduction of the critical 500Hz–2kHz speech intelligibility band. The high-frequency horn completes the three-way system with controlled directional output across the top octaves.

The THH is configured for bi-amplification, requiring an external amplifier and active crossover or DSP-based loudspeaker management system for operation. This approach gives system engineers full control over drive levels, crossover points, and equalization for each frequency section, making the THH integrable into both portable touring rigs and permanently installed signal chains. Fitted handles and castors facilitate stage-level positioning by a single technician or small crew. The five-year limited warranty reflects the product's build quality and Martin Audio's confidence in its field reliability over extended service life.

Key Features

• All-Horn Three-Way System — Full-range horn loading maximizes acoustic efficiency and sustained SPL output for large-venue reinforcement applications.
• Hybrid LF Section — Martin Audio's proprietary Hybrid loading combines horn and reflex principles for extended low-frequency bandwidth with horn-class efficiency.
• Phase-Ball Loaded Mid-Driver — Phase-ball coupler optimizes midrange horn loading for smooth, high-efficiency reproduction of the critical speech intelligibility band.
• Horizontal Trapezoid Format — Wide horizontal coverage pattern suited to large-stage and wide-format auditorium PA positions.
• Bi-Amp Configuration — External active crossover or DSP controller drives LF and HF sections independently for optimized system performance and protection.
• Fitted Handles and Castors — Stage-level repositioning by small crew without additional handling equipment in portable touring deployments.
• Five-Year Limited Warranty — Extended warranty coverage reflects the THH's build quality and field reliability specification for professional touring and installation use.

Typical Applications

• Auditorium and performing arts venue — main PA system for large-format theatrical and live music productions
• Multi-purpose room and large venue — permanent installed PA for wide-format spaces requiring high SPL and controlled dispersion
• House of worship — high-output horn-loaded main PA for large sanctuaries with demanding program content
• Live event production — touring main PA system for large club and outdoor stage applications

Technical Specifications

Frequently Asked Questions

Is the THH a powered loudspeaker?

No. The THH is a passive loudspeaker requiring external bi-amplification and an active crossover or DSP loudspeaker management system. This configuration gives system engineers full control over drive levels and system optimization.

What is the difference between the THH and THV?

Both the THH and THV are all-horn, three-way bi-amp loudspeakers sharing the same driver complement and Hybrid LF technology. The THH is configured in a horizontal trapezoid format for wide horizontal coverage, while the THV is configured vertically for tall, narrow coverage patterns. Selection depends on venue geometry and system design requirements.

What is Martin Audio's Hybrid LF section?

The Hybrid LF section combines horn-loading with reflex-tuning principles in the low-frequency section of the enclosure. This approach extends usable low-frequency bandwidth beyond what a pure front-loaded horn would achieve, while retaining the high acoustic efficiency characteristic of horn-loaded designs.

What DSP controller or amplifier does Martin Audio recommend for the THH?

Martin Audio specifies amplifier and DSP controller pairings for the TH Series. Contact Creation Networks for system design assistance and amplifier pairing recommendations.

Is the THH suitable for permanent installation?

Yes. The THH is specified for both large-scale touring and permanent large-venue installation applications. Flying hardware compatibility and installation rigging requirements should be confirmed with Creation Networks during system design.

What venues typically use the THH?

The THH is deployed in large nightclubs, concert venues, outdoor stages, large-format houses of worship, and performing arts centers where high SPL, controlled dispersion, and extended bandwidth are required from a single PA cabinet.

What warranty does the THH carry?

The Martin Audio THH includes a five-year limited warranty, reflecting its specification for extended professional touring and installation service. Contact Creation Networks for warranty details.
