Poly-Mica Woofer Cones: Each woofer features a Poly-Mica cone
and butyl rubber surround. Mica adds strength and heat resistance to polypropylene,
resulting in reduced distortion and improved reliability.
Silk Dome Tweeters: The 1" wide-range silk dome tweeters
offer clean, non-fatiguing sound even under extreme high frequency demands.
Tweeter Mounting Options: The tweeters can be flush mounted
using the supplied flush mount bracket and ring. Once mounted, the tweeters can
swivel approximately 30° for optimum imaging. The tweeters can also be mounted
in factory tweeter locations behind factory tweeter grilles using the supplied
stealth mounting bracket.

Woofer Mounting: Without an adapter, the woofers fit standard
6-3/4" applications. Given their required cutout, they will also fit standard
6-1/2" applications without an adapter, but new screw holes must be drilled.
Using the included adapter brackets they can be mounted in a variety of standard
3-hole 6-1/2" applications, Ford 4-hole 6-1/2" applications, and
non-standard 6-3/4" applications, without any modification.
Crossovers: The Alpine SPS-610C features low-pass
crossovers attached to each woofer's input terminal and high-pass crossovers
in-line with the tweeters' speaker wires.
