Alpine optimize their SPS-610C 6-3/4" component speakers for great range and impressive tone definition, even at low power levels. You can connect these versatile Type-S Series speakers to your factory stereo for an immediate sonic improvement, or hook them up to a powerful aftermarket stereo or amp for increased performance.
Mineral-fortified polypropylene cones are exceptionally stiff, yet lightweight, which means they can push out accurate bass and deliver clear midrange. Resilient rubber surrounds help keep the woofer centered for accurate cone movement, reducing distortion. You can aim the separate silk dome tweeters toward you so that they deliver the strongest possible stereo image. Woofer grilles are not included — factory grilles are appropriate for most installations.
Note: Alpine describes this model as a 6-1/2" speaker. Most manufacturers designate this same frame size as a 6-3/4" speaker. For simplicity's sake we list it as a 6-3/4" speaker.

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.
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.
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.
