Diaphragm for EV DH1K DH1M Driver - Direct Replacement for ELX ZLX EKX

Our review of the Diaphragm for EV DH1K and DH1M driver finds it best suited for technicians and owners who need a precise, reliable replacement for a damaged high-frequency driver. The single biggest reason to buy is the proven materials and fit: a titanium dome with an edge-wound voice coil on a Nomex former closely matches the original OEM spec, restoring clarity and presence to Live-X, ELX, EKX and ZLX systems without compromise. This is a focused repair part rather than an upgrade, and it excels when compatibility and accurate voice-coil dimensions matter.

Key Features

• Exact compatibility: Designed to replace EV DH1K and DH1M drivers used across ELX, ZLX and EKX series so installers avoid fitment guesswork.
• Titanium dome: The titanium diaphragm offers a clear, detailed high end that holds up under live use and reproduces vocals and cymbals accurately.
• Edge-wound voice coil: The edge-wound voice coil on a Nomex former provides consistent thermal handling and reduces compression during prolonged use.
• Precise dimensions: With a 1-7/16 in (37mm) voice coil and 3-3/8 in (86mm) diameter, the part matches driver geometry for predictable acoustic behavior.
• Trusted source: Supplied as a premium TSE Audio replacement from a specialist repair shop with decades of speaker service experience, it supports reliable long-term repairs.

Who It's For

This diaphragm is intended for audio technicians, rental house engineers, and owners of Live-X, ELX, EKX and ZLX powered speakers who need a correct-fit replacement to restore original performance. If you maintain ELX 112, ZLX12, EKX15 or similar enclosures and value accurate high-frequency response, this part is a practical choice.

It is not aimed at hobbyists looking for a tonal upgrade or universal repair kits; those seeking a different sonic character or non-standard modifications should consider alternative diaphragms or a full driver swap rather than this direct replacement.
