Description
DS18 PRO-SDF6
The PRO-SDF6 is a 6.5″ round bolt-on horn diffuser designed to improve sound dispersion and clarity when used with compatible compression drivers or tweeters. It is not a speaker, but a sound-shaping accessory that helps control and direct high-frequency output more efficiently. The diffuser’s horn-style design increases projection, enhances vocal presence, and ensures clearer treble performance at high volume levels. Built with durable materials for long-term reliability, the PRO-SDF6 is ideal for car audio SPL systems and professional PA applications where focused and controlled high-frequency sound is required.
