Know before you buy
This horn driver is specifically engineered for high-output PA systems. It is designed to cut through dense audio environments, making it ideal for professional sound reinforcement or demanding custom audio setups where clarity and projection are the priority.
The SDEH-04 is sold individually. This allows you to purchase the exact number of drivers needed to complete your specific speaker configuration without being forced into a set.
You will need a mounting cutout of 4" x 4" and a mounting depth of 4.7". The overall frame measures 4.5" x 4.5", so ensure your baffle or mounting surface has enough clearance for these dimensions.
It is built with a durable ferrite motor structure and engineered for extremely low distortion. This combination ensures that the audio remains clean and precise even when you are pushing the system to high output levels.
This driver covers the high-frequency spectrum from 4kHz to 20kHz. It is designed to handle the upper registers of your audio, providing the crisp, detailed projection typical of high-performance horn-loaded systems.
