830875 HDS Nomex 6½″ Midwoofer Peerless Datasheet

HDS Nomex
6½″ Midwoofer

Type Number: 830875

Features:

The High Definition Sound (HDS) NOMEX Series offers high-quality 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.
