Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
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.
