Introducing the Martin Audio Blackline Q44 Speaker

Martin Audio Blackline Q44 is a 2-way passive array speaker with a strong British sound, designed for spaces requiring even sound coverage and high performance quality.

With a slim, modern design, the Q44 is not only suitable for professional line array systems but also for fixed installation in cafes, conference rooms or high-end restaurants.

The combination of Differential Dispersion acoustic technology and the “Signature British Sound” philosophy helps Martin Audio Blackline Q44 deliver faithful, detailed and emotional sound in all music genres.

Technical parameters of the product to consider:

Classification: This is a 2-way passive array speaker line, meaning the speaker system has no built-in power (passive) and is divided into two separate frequency ranges: low range (LF) and high range (HF). This structure helps Martin Audio Blackline Q44 to reproduce sound accurately and is easy to combine with amplifiers or dedicated processors.

• Driver Configuration: Martin Audio Blackline Q44 uses 4 4-inch (100mm) LF speakers with 1-inch (25mm) voice coils, using ferrite magnets – a material with high magnetic stability, for solid and durable bass.
  The HF tweeter is a compression driver. 1 inch size with PETP dome film (Polyethylene Terephthalate Polymer), famous for its ability to reproduce smooth, bright treble without being harsh.
• Frequency response range: Operates within 82Hz – 17kHz (±3dB), and can go down to 63Hz at -10dB, allowing full reproduction of mid-high ranges, suitable for musical instruments and vocals. The low bass range can be extended when combined with the Martin Audio S15 or PI118 subwoofer.
• Power and SPL: 200W AES rated power, 800W peak, allowing the speaker to operate stably for a long time. Maximum SPL 125dB (peak), equivalent to the volume of a small live performance. This parameter shows that the Q44 can ensure powerful sound while still being clean and without distortion.
• Sensitivity: Reach 90dB (2.83V/1m) This means that with just a small power source, the speaker can still produce a large volume, helping to save amplifier energy.
• Nominal impedance: 8 Ohms Standard level allows flexible matching with many different types of power amplifiers, especially the lines Martin Audio VIA or iKON.
• Dispersion: Horizontal 100°–120°, vertical 40°, designed with Differential Dispersion horn technology. This is a typical technique of Martin Audio, helping the sound spread evenly - listeners near or far still feel the same volume and quality.
• Crossover frequency: 2.4kHz (Passive) Reasonable crossover point helps the speaker reproduce smooth midrange without "falling apart" between the LF and HF ranges.
• Connection: Equipped with 1 Neutrik NL4 port (1+/1–) Professional connection standards, ensuring stable signal transmission and anti-interference.
• Amplification requirements: Q44 works optimally when combined with Martin Audio DX0.4 / DX0.6 / DX4.0 signal processor with VIA or iKON amplifier, ensuring correct response and hardware protection.
• Materials & Finish: Birch plywood, textured black or white finish, durable and scratch resistant. Perforated steel mesh with dustproof lining, fixed with screws - increased durability and aesthetics.
• Installation options: There are 3 M8 threaded holes, 1 M6 hole, 4 M6 holes for wall mounting or array rigging, with M20 (35mm) pole mount – making Martin Audio Blackline Q44 easy to install in a variety of locations.
• Handle: Made from recycled ABS, environmentally friendly, supports fast movement in mobile systems.
• Dimensions & weight: 150 × 800 × 187 mm, weighs 7.5 kg – extremely compact compared to a 4-driver array speaker, easy to hang, cluster or move.

Outstanding features of Martin Audio Blackline Q44 Speaker

Martin Audio Blackline Q44 speakers are a product that brings together the quintessence of British audio technology, manufactured by Martin Audio with a focus on high performance, wide sound coverage and the ability to reproduce acoustic details at all frequencies.

More than just a performance device, the Q44 is also a symbol of the philosophy of “Unite the Audience – Connecting listeners through every sound range” that Martin Audio has pursued for over 50 years.

• Differential Dispersion Technology – Smart acoustic control solution: Martin Audio equips the Martin Audio Blackline Q44 with horn Differential Dispersion, an exclusive technology that distributes sound energy in an uneven fan shape, so that the sound reaching the listener's ears is always even whether standing near or far from the speaker.
• Compact modular design – Flexible for any system configuration: With a width of only 150mm and a weight of 7.5kg, the Q44 is designed to be hung vertically, mounted horizontally or combined into an array, extremely convenient for both fixed and mobile installations.
• Powerful performance – SPL up to 125dB: The 125dB peak SPL delivers loud, clear, detailed sound while maintaining a high level of cleanliness. Combined with the VIA/iKON amplifier and DX4.0 processor, the Martin Audio Blackline Q44 achieves extremely stable phase accuracy and response, ensuring faithful sound throughout the entire line array system.
• Durability – Aesthetics – Environmental protection: The speaker enclosure is made of multi-layer birch plywood, a material commonly used in high-end touring speakers, to reduce resonance and increase structural strength. The textured paint is moisture-proof and impact-resistant, suitable for tropical climates.
• Flexible compatibility – Easy to combine and expand: Martin Audio Blackline Q44 works optimally when combined with DX0.4 / DX0.6 / DX4.0 processor and VIA or iKON amplifier, helping to synchronize phase, protect speaker membrane and optimize power. When connecting multiple Q44 speakers vertically, users can build a mini line array with even coverage, clear stereo sound image, without the need for complex calibration equipment.
