The Meyer Sound MS 818 HTS is a high-performance 18-inch subwoofer cone assembly, designated as a genuine factory replacement part for Meyer Sound's 650-P and 600-HP subwoofer cabinets. The "HTS" stands for High-Temperature Suspension, indicating that the driver is engineered with materials that can withstand the extreme thermal and mechanical stresses generated during high-power, low-frequency reproduction. This cone is not a stand-alone speaker but the core transducer that, when installed in its proprietary enclosure and driven by Meyer's matched amplification and processing, delivers the powerful, articulate, and controlled bass response for which Meyer Sound systems are renowned in concert touring, fixed installations, and high-end audio applications.

The driver is built to exacting specifications, featuring a massive motor structure with a long-throw voice coil, a rigid composite cone, and a durable surround and spider assembly. These elements work together to provide high power handling, low distortion, and precise transient response, enabling the subwoofer to reproduce the deepest musical notes and impactful sound effects with authority and clarity. Replacing a worn or damaged cone with this genuine OEM part ensures that the cabinet's original acoustic performance, reliability, and longevity are fully restored, maintaining the system's designed frequency response, output capability, and sonic character.

For owners and technicians maintaining Meyer Sound systems, using the MS 818 HTS cone is critical for preserving the value and performance of their investment. It is a specialized component intended for professional repair by qualified technicians, as proper installation and alignment are essential for optimal performance and to prevent further damage. This part exemplifies the professional audio industry's commitment to serviceability and long-term support, allowing critically acclaimed loudspeaker systems to continue performing at their peak for decades.
