HDS Exclusive 8″ Woofer

Type Number: 830884 Features:

This High Definition Sound (HDS) line of products push the performance limits of midbass audio transducers in a range of sizes - from the standard 205mm (8-inch) model, down to the very small 106mm (4-inch) model. Feature-rich and utilizing copper for the lowest distortion possible, the high-end HDS Exclusive Series takes maximum advantage of over 80 years of R&D experience to help systems designers build the world's best audio products. See architecture notes for HDS Platform

Driver Highlights: Nomex diaphragm, 33 mm coil, AL, CU, LS, Phaseplug See Application Notes
