Alpine SPC-170C C-Series

6.5" Component Speakers

C-Series Speakers—performance and quality at a great price

The all-new C-Series of component and coaxial speakers are designed and built to handle high power levels, but are also extremely efficient making them perfect for factory sound upgrades too.

These speakers deliver great sound quality, due to a soft dome tweeter, square voice coil wire with Kapton bobbin and an audio tuned capacitor.

PP Woofer / Integrated Wave Guide

The C-Series polypropylene woofer cone is extremely rigid and light weight, this enables superior cone velocity for accurate sound and extended bass response.

Furthermore, the component speakers are designed with an integrated wave guide to ensure uniform sound dispersion for a clean response and optimised sound imaging.

Butyl Rubber Surround

The C-Series are equipped with a butyl rubber surround to achieve a greater cone movement and x-max capabilities The results, high power output, sound accuracy and linearity, as well as superior bass response extension. This material is long lasting and robust too, so that your sound never degrades over the life of speaker.

Compact Crossover / Silk Tweeter

These speakers are easy to install due to the compact snap fit silk dome tweeter, swivel mount, and flush install bracket. The crossover network is small and can be separated to allow use in factory wiring.

Included 6″ Fit Adaptors and Grilles 

The 6″ fit adaptors (with SPC-170/C) provides versatility so that these speakers can fit virtually any 6″ to 6-1/2″ installation. The included 6″ or 6×9″ grilles make the C-Series ready for any custom installation.
