HDS Nomex 8″ Woofer Type Number: 830869 Features: The High Definition Sound (HDS) NOMEX Series offers highquality solutions for both multi-way speaker systems and vented box applications. Featuring "shorting rings" for low distortion and coils offering perfect linear compatibility with NOMEX cones, these audio transducers are characterized by their very open, very rich sound character. See architecture notes for HDS Platform Driver Highlights: Nomex diaphragm, 33 mm coil, AL See Application Notes Go to Application Notes. Go to Architecture Notes
