Description

18 Sound 6M44 – Precision 6.5″ Mid-Bass Driver for Compact High-Performance Systems

The 18 Sound 6M44 is a high-efficiency, compact 6.5-inch mid-bass driver engineered to deliver articulate midrange and controlled low-end performance in professional loudspeaker designs. Crafted in Italy by 18 Sound, this ferrite-magnet transducer combines vocal clarity, durability, and space-saving design—ideal for PA systems, stage monitors, and installation systems requiring accurate sound with a small footprint.

Whether installed in a touring cabinet, fixed venue, or a custom audio solution, the 6M44 strikes an ideal balance between size and sonic output. Its advanced motor, lightweight structure, and broad frequency response allow designers to achieve powerful, high-quality results in compact enclosures.

Defined Mid-Bass Clarity and Control

At the heart of the 6M44 lies a 44 mm (1.75”) copper-clad aluminum voice coil, wound on a fiberglass former for fast transient response and exceptional thermal durability. This voice coil design enables dynamic, distortion-free performance across a 140 Hz to 7 kHz frequency range, offering extended coverage and smooth tonal balance throughout the upper bass and vocal spectrum.

This makes the 6M44 particularly well-suited to demanding applications such as vocal projection systems, compact front-fills, line arrays, or two-way monitor wedges where clean and natural midrange is paramount.

Ferrite Magnet Motor with Efficient Cooling

Unlike lightweight neodymium alternatives, the 6M44 employs a ferrite magnet system that offers powerful, consistent magnetic flux. This traditional magnet design ensures efficient heat dissipation and reduced power compression under heavy load.

This results in stable, high-output performance over longer periods, ideal for live audio environments and installations where reliability and endurance are critical.

Efficient Output in a Lightweight Package

Delivering a sensitivity of 95dB (1W/1m) and a robust 200 W AES / 350 W program power handling, the 6M44 excels in systems where high acoustic output must be achieved with minimal amplifier resources. This efficiency, paired with its compact size and low weight of approximately 3.4 kg, allows for flexible integration into portable enclosures and flown configurations.

Sound system designers benefit from its excellent output-to-weight ratio, making it an ideal transducer for mobile setups and rig-friendly PA systems.

---

Low Distortion, High Precision

The 6M44 integrates Single Demodulating Ring (SDR) technology—an aluminum ring positioned in the magnetic gap to reduce intermodulation distortion and improve transient clarity. Combined with its ventilated structure, this technology delivers low distortion levels, clean output, and tonal transparency, even during aggressive dynamic passages.

Whether you’re reinforcing speech, vocals, or instruments, the SDR-equipped motor ensures that every nuance of your mix is delivered accurately and consistently.

Rugged Construction for Real-World Use

Durability is a hallmark of the 6M44. It features a weather protected cone, offering both rigidity and environmental resistance—ideal for humid or semi-outdoor applications. Its M-roll suspension provides precise mechanical control of the cone, extending linear excursion and minimizing distortion during high-output bursts.

A stamped steel basket offers a rigid foundation that supports the driver’s components, reducing unwanted resonance and contributing to its robust build quality. This makes the 6M44 an ideal fit for professional-grade sound reinforcement systems that demand reliability under continuous use.
