Alpine C-Series SPC-690 - 6x9" Coaxial Speakers
The C-Series (PP) polypropylene woofer cone is light weight and extremely rigid, this provides precise cone velocity for accurate sound reproduction and an extended bass response. Moreover, the component speakers are equipped with an integrated wave guide to ensure uniform sound dispersion and optimised sound imaging.
The C-Series are equipped with a butyl rubber surround to achieve a greater cone movement and x-max capability. This results in 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 the speaker.
The included 6″ or 6×9″ grilles make the C-Series ready for any custom installation.
