6.5” Round Bolt-On Horn Diffuser

DS18 PRO-SDF6R

6.5” Round Bolt-On Horn Diffuser

If you're running 6.5” midrange loudspeakers, DS18’s PRO-SDF6R is your secret weapon for sharper projection and cleaner vocals. This round bolt-on horn diffuser upgrades your front stage with a wide 90° dispersion, giving your mids the focus and range they’ve been missing.

Built for the Culture
Made from tough ABS with a clean matte black finish, the PRO-SDF6R adds an aggressive look to your setup—perfect for show builds or open-air street systems where every decibel counts.

Drop-In, Bolt-On
Designed for easy bolt-on installation, the PRO-SDF6R fits any standard 6.5" midrange speaker with matching bolt patterns (6.26"/159mm speaker pattern, 8"/205mm horn flange). It’s a direct performance upgrade for DS18 PRO-X, PRO-GM, or any comparable 6.5” loudspeaker that needs better throw.
