Kentech HS1213D Replacement Diaphragm for HS1213 Compression Driver

• Precision Acoustic Restoration: The Kentech HS1213D is a factory-specification replacement voice coil and diaphragm assembly explicitly engineered to rebuild and restore damaged, blown, or distorted HS1213 reflex horn compression drivers.
• Direct Drop-In Integration: Tailored with exact alignment tolerances to perfectly fit the driver housing of the Kentech HS1213 12-inch aluminum reflex horn speaker, eliminating the need to replace the entire expensive horn assembly.
• Calibrated 8-Ohm Voice Coil: Features a precision-wound 8-Ohm nominal impedance voice coil layer, ensuring seamless electrical matching with standard low-impedance public address amplifiers following service restoration.
• High-Temperature Phenolic Dome: Built with a resilient, heat-treated phenolic or composite resin dome membrane designed to endure continuous acoustic pressure and resist thermal fracturing under peak power loads.
• Pre-Aligned Self-Centering Frame: The voice coil assembly is mounted to a structured composite alignment ring that drops cleanly over the magnet pole piece, simplifying field repairs and minimizing the risk of coil rubbing.

Features

• Cost-Effective System Repair: Provides public address installers and maintenance technicians with a cost-saving alternative to replacing full outdoor paging horns by addressing the most common failure point directly.
• Optimized Vocal Intelligibility: Retains the native mid-range acoustic tuning of the HS1213 platform, ensuring restored horns continue to project highly intelligible spoken messages, paging commands, and sirens.
• Excellent Thermal Heat Dissipation: The voice coil is wound on a rugged, high-grade former material that efficiently sheds structural heat, preventing premature wire delamination or burnouts during extended broadcasts.
• Integrated Solder or Push Terminals: Equipped with robust, pre-fixed terminal link points matching the internal polarity layout of the host horn chassis, making wire hookups straightforward.
• Tough Industrial Outdoor Durability: Built from moisture-resistant materials designed to withstand the typical humidity changes and internal temperature shifts common in outdoor horn speaker enclosures.
