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.
