Why install component speakers?

A component speaker system gives you the best possible performance from your car audio system. A system consists of separate woofers, tweeters, and crossovers, each designed to cover one specific range of frequencies. As separate components, the woofer can move freely to deliver more powerful performance, while the tweeter can be custom-mounted in a better spot up closer to your ears, revealing a whole new world of detail. Separate crossovers are far superior to the simple filters wired into full-range speakers, so the components work together for smoother, more focused sound.

Our take on the Rockford Fosgate Prime R1675-S

by John Pollard

The woofers are built tough so they can play at high volume.

Excellent factory replacement

Whether you're building your first system or replacing some burned-out factory speakers, Rockford Fosgate's Prime speakers offer clean, powerful performance that'll keep you and your friends rockin' as you drive. Plus, Prime speakers are a great way to get Rockford Fosgate sound quality without destroying your bank account.

Better components give you better detail

The Prime R1675-S component speaker system sports stiff mica-injected 6-3/4" polypropylene woofers that deliver strong drums and bass, along with clean reproduction of the midrange frequencies. The separate Mylar tweeters add the excitement of strong high-frequency response to your music without a trace of harshness. Built-in crossover networks divide the frequencies going to each driver, so all your music plays faithfully. Grilles are included.

Note: The oversized terminals on these speakers won't connect to a Crutchfield wiring harness. We recommend that you buy a 10-pack of female quick slides that you can splice onto our harness.

Features

Mica Injected Polypropylene Woofers: The woofer cones are mica injected polypropylene. This material is light weight and rigid for decreased distortion and improved bass response.

Tweeter: The 1/2" Mylar tweeters are a balanced dome design. A semi-dome tweeter has a dome placed inside a cone. Balanced dome tweeters are semi-dome tweeters with equal reproduction area given the cone and dome portions of the tweeter. Out of the box, the tweeters are mounted in the flush mount housings. An angled surface mount housing is also included, and the back of the the flush mount housing and the top of the angled surface mount housing are combined to make the (non-angled) surface mount housing. Once mounted, the tweeters swivel so you can direct them toward the listening positions.

Tweeter Dimensions:

	Frame Diameter	Frame Width	Frame Depth	Cutout Diameter	Mounting Height	Mounting Depth
Flush Mount	2.125"	N/A	N/A	1.83"	0.34"	0.752"
Surface Mount	1.815"	N/A	N/A	N/A	1.1"	0.66" (Screw Depth)
Angled Surface Mount	N/A	1.815"	1.845"	N/A	1.661"	0.59" (Screw Depth)

Crossovers: A 6 dB/octave high-pass crossover is integrated into the case of each tweeter. The woofers have two spades on each terminal; the wire from the tweeter, as well as the wire from the source are connected there.
