Detailed review of Martin Audio THS Speakers

Sound Quality – Accurate, True and Powerful

The Martin Audio THS delivers the signature sound quality of a three-way bi-amp loudspeaker, where each frequency band (LF, MF, HF) is amplified independently to maintain low distortion and extremely wide dynamic range. Thanks to a 15” neodymium bass driver with a 4” voice coil combined with polymer radiators in the mid and high ranges, the sound is detailed and clearly separated.

The bass is deep but well controlled, not boomy; the midrange is energetic, reproducing natural, rustic vocals; the treble is bright, smooth and not harsh. The triple-axis point source structure helps the frequency bands to be in phase, creating a precise stereo image, no matter where the listener stands in the auditorium.

With its full-range response, Martin Audio THS achieves a balance between power, fidelity and uniform dispersion – something few speakers in its class can achieve.

Design and durability – Solid and sophisticated to British standards

In terms of design, Martin Audio THS uses a trapezoidal enclosure made from multi-layer birch plywood, coated with scratch-resistant and moisture-resistant polyurethane paint. This structure not only increases mechanical strength but also minimizes internal resonance, ensuring stable sound quality when operating at high intensity.

The powder-coated front grille protects the driver from impact and dirt, while a flexible suspension system allows for flown or ground-stack installation. Overall, the Martin Audio THS loudspeaker is both aesthetically pleasing and built to last in the harshest outdoor and professional performance environments.

Thanks to the use of neodymium drivers that are 40% lighter than traditional ferrite, the speaker achieves high performance while remaining compact, convenient for moving and setting up.

Performance and power – Large, stable coverage across all frequency bands

Martin Audio THS speakers achieve incredible sound performance thanks to their 3-way bi-amp configuration, allowing each frequency range to be amplified and processed independently. The speaker's sensitivity is around 100 dB (1W/1m), while the maximum sound pressure (max SPL) can reach up to 135 dB, enough to cover a space with a capacity of 1000–2000 people.

The system's peak power reaches over 1300W, ensuring strong, clean, uncompressed sound even at high volume levels. Thanks to the use of 4-inch neodymium voice coils and a polymer heatsink system, Martin Audio THS maintains good thermal stability, avoiding power loss during continuous operation for long periods of time.

The combination of optimized mechanical design and advanced sound processing techniques enables the speaker to perform effectively in any performance environment, from enclosed spaces to outdoors.

Acoustic control and directionality – Optimized for any space

One of the great advantages of Martin Audio THS is its outstanding acoustic directivity control. The speaker uses a user-rotatable horn with 85° horizontal x 50° vertical orientation, allowing the sound engineer to easily customize the coverage area for each space.

As a result, THS can minimize hot spots or dead zones, providing uniform coverage and consistent SPL across the entire audience area.

When multiple Martin Audio THS loudspeakers are combined in an array, precise directional control reduces crosstalk and enhances mid- and high-frequency resonance, creating a seamless and natural audio experience.

DISPLAY 3 software application – Improved performance and setup accuracy

Martin Audio THS is powered by DISPLAY 3 software, an advanced acoustic simulation tool developed by Martin Audio. This software allows sound engineers to model the space (acoustic modeling), pre-calculate SPL coverage, directivity and phase alignment between speakers.

With DISPLAY 3, system setup is faster, more precise and less time-consuming, especially in performances that require high soundstage precision. When combined with the Martin Audio iKON amplifier or DX4.0 processor, THS achieves ideal performance with EQ, limiter, delay and phase precisely tuned according to the company's presets.

This is where Martin Audio's professionalism shines – not only selling hardware but also providing a comprehensive software ecosystem for users.

Real Experience – Strong Emotions, High-Class Tone

In real performance, Martin Audio THS clearly shows the “British Sound” identity – balanced, rustic but still full of power. The sound has thickness, detail and clear separation between frequency bands, helping singers, musicians or listeners feel every nuance of music.

In live performances, THS reproduces vocals faithfully, with tight bass and bright treble without harshness. When combined with Martin Audio SX Series subwoofers, the overall system delivers a wide soundstage, uniform coverage and powerful energy typical of professional speakers.

Therefore, Martin Audio THS is considered by many sound engineers as "the most stable and faithful performance speaker line in its price range", suitable for stage performances, theaters or high-end fixed systems.

Frequently Asked Questions about Martin Audio THS Speakers

1. Is the Martin Audio THS Full Range Speaker suitable for small spaces?

No, the Martin Audio THS is optimized for medium-large spaces requiring high SPL and tightly controlled coverage, thanks to its 3-way bi-amp configuration and 85°×50° dispersion. In small rooms (<120 m²) or with low ceilings, sound energy (SPL) and room compression can exceed optimal levels, causing early reflections and reduced speech intelligibility. For small rooms, you should consider compact models in Martin Audio Speakers or group auditorium speaker small size (e.g. CDD series) to achieve more suitable directivity and coverage uniformity.

2. Do Martin Audio THS speakers need to be paired with a subwoofer?

Yes, if you need to extend the bass range and headroom for live shows, EDM or speech + music in large spaces, because THS is full-range 3-way but the separate sub helps increase LF extension and reduce power compression. Reference configuration: SX118 (compact, portable) or SX218 (high bass pressure for stage). Crossover suggestion: LPF sub 80–100 Hz, HPF THS 70–90 Hz, slope 24 dB/oct, fine-tune phase alignment/polarity for good summation at the crossover frequency.

3. What amplifiers/DSPs are compatible with Martin Audio THS and how do they connect?

THS works optimally with Martin Audio iKON iK42 amplifier , and DX4.0 processor with factory-standard FIR/IIR presets, ensuring precise gain structure, limiters, FIR phase linearization, and voicing. For other systems, adequate voltage swing, damping factor, and bi-amp configuration according to LF/MF-HF impedance are required. The system can integrate Dante/AES-EBU via DSP.

4. What is the typical configuration for an 800–1500 seat auditorium?

Typical is 1–2 THS per left/right cluster, combined with 2–4 sub/side (SX118/SX218) depending on coverage width and target SPL (~96–100 dB(A) in the far area). The speaker-to-target audience distance of 20–35 m should be checked with DISPLAY 3 to optimize splay angle, aiming, and time-of-flight delay. The target is ΔSPL ≤ ±3 dB in the main audience area.
