Speaker Specifications

Series
This is the manufacturer product line of speakers.
Prime (Rockford Fosgate)
Priced Per
Car Speakers are typically sold in pairs so you will receive 2 speakers for each speaker purchase on speakers marked "Priced Per Pair". If a speaker is marked "Priced Per Each" then the speaker is sold individually and each purchase you make will result in 1 speaker. High-powered tweeters, midrange and full-range pro audio for car speakers are typically sold per each speaker.
Pair
Speaker Size
Refers to the size of the speaker measured in inches. Every vehicle has standard application sizes. Please use our vehicle fitment guide for your vehicle's specific speaker sizes if you do not know them.
5-1/4"
Design
The number of individual drivers in a car speaker. Speakers with 2 drivers are known as a 2-way, and 3 drivers are known as a 3-way. Component systems are often referred to as "separates" because the tweeter is not attached to the midwoofer (main speaker driver) and mounts separately in a location such as a door post. Component systems typically come with an external crossover so you can easily adjust the high and low frequencies sent to both the midwoofer and the tweeter. Center channel speakers are great for those looking to have surround sound in their vehicle.
2-way Component System
Tweeter Design
Designs such as cone, dome, semi-dome, balanced dome, and whizzer are most popular. Cone tweeters are simple, efficient and typically are the most reasonably priced. Dome tweeters are used in most home speakers, and provide a smoother and more accurate sound. Semi-dome design is one with a dome placed inside a cone. A Balanced dome driver is a semi-dome with equal reproduction area given the cone and dome portions of the driver. A whizzer tweeter is a separate tweeter cone driven by the voice coil of the woofer.
Dome
Tweeter Composition
Materials such as polypropylene, silk, cloth, and paper are the most common, where as many more recent tweeters are now manufactured with composites such as Aluminum, Titanium, Mylar, and other materials.

PEI is an acronym for "Polyetherimide" which is an amorphous, amber transparent, high-performance thermoplastic.

Mylar
Woofer Composition
Lightweight woofer cone materials are essential for efficient operation. Poly cones produce exceptional sound and are sturdy against various changes in temperature. Paper cones are very efficient, and when treated for moisture resistance, will perform at a high level. Poly refers to polypropylene, which is thermoplastic or fibers that are polymers of propylene. IMPP refers to injection molded polypropylene, a commonly used process and material in speakers.
Mica Injected Polypropylene (MIPP)
Woofer Surround
A speakers surround is part of the suspension system. The surround protects the cone and prevents it from being displaced as it flexes out from the basket. It is usually made of a durable material like treated foam or rubber in order to withstand the strenuous job of producing bass frequencies.
Foam
Peak Power Handling
Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements. The Peak power handling specification is typically rated per speaker unless otherwise noted.
80 watts
RMS Power Handling
The RMS power is the amount of power the speaker requires to operate safely and properly. RMS Power Handling refers to the amount of power a speaker can handle on a continuous basis. We recommend powering your speakers or subwoofer with 80%-120% of its recommended RMS rating. The RMS power handling specification is typically rated per speaker unless otherwise noted.
40 watts
Sensitivity
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
 
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
85 dB
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
58 - 20,000 Hz
Impedance (Per Voice Coil)
The load value (in ohms) that the speakers present to the amplifier per voice coil - the amount of resistance to the current flow. This is a key specification as subs wired in parallel or low impedances can create problems with your amplifier and potentially void all warranties. We encourage you to ask our support department prior to purchase if you do not understand which impedance level will suit your application best.
4 ohms
Shallow Mount Installation
This means that the subwoofer/speaker is designed to be installed in areas that do not have a lot of space. Shallow mount subwoofers are typically found under a seat or behind the seat in some trucks.

Shallow mount speakers will typically have a mounting depth of 2" or less, while shallow mount subwoofers will typically have a mounting depth of 3" or less.

Yes
Top-Mount Depth
The depth when installed on top of the mounting surface. Measured from the bottom of the speaker's magnet to the bottom of the mounting holes on the rim of the speaker.
2"
Bottom-Mount Depth
The depth when installed from the bottom of the mounting surface. Measured from the bottom of the speaker's magnet to the top of the mounting holes on the rim of the speaker.
1-9/10"
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches or millimeters, required to contain the speaker.
4-3/4 x 4-3/4 
Speaker Grilles
A grating or screen of metal or plastic bars or wires, mounted in front of a speaker as protection. If yes, the speakers will include matching speaker grilles. If no, there are no grilles included.
Yes

Fosgate Prime is better than you'd expect for the money

September 17, 2012

I'd highly recommend these for anyone running straight off an aftermarket head unit or as factory replacements on a stock unit. I have an OLD Alpine head unit that's 60x4 and it pushes these just fine. Very crisp, clean tweeters that are natural sounding and not too "tinny". The midbass and vocals are good...not spectacular, but good. That may be because I don't have the adjustments on my head unit for midrange though...only bass and treble. About the only drawback that I can see is that the tweeter mounting is somewhat bulky and really shows if you use surface mounting. In a flush mount situation they would look really good. I have an FI BTL 18 in a 5.5 cubic foot box tuned to 36 Hz on 1800 watts rms and they keep up just fine using just the head unit to push them. Great value for the cash.

Great replacement front speaker

October 8, 2011

I got these as a replacement for the front speakers on my 2002 Pontiac Grand prix, Non-Bose. I used the adapter wire set so it was a plug and play affair. I used the factory tweeter wiring harness and cut a hole in the factory speaker grille to mount the tweeters. Now the front staging is brilliant. Much better than the factory location. Total install time was around 3 hours. Buy a bunch of door panel clips because now is a great time to change them, Ask me how I found out. Now it is time to add an amp and sub. Rock On!!

Best bang for your buck!

April 6, 2011

I have 4 sets of these in my Subaru STI, one in every door. All 4 are powered by a Rockford Fosgate Prime R300-4. I am beyond happy with the clarity of the speakers. The highs are incredible. It sounds like the hi-hats are in the back seat. The mids are smooth and not distorted in the slightest. The lows leave something to be desired tho. Lows tend to distort at higher volume. I set my system up so that these components do not need to handle the lows, my sub does that. All in all, I would recommend these to the person who's looking for clarity in their system. If your a huge hip-hop fan, these probably aren't the best option for you.

I installed a JVC receiver, the components front and rear, and a 10" Fosgate sub with amp and cap...the highs, mids, and lows are incredible. You don't realize the acoustics you're missing until you do something such as this (chimes in background, etc).

Nice speakers all the way round. Just got em hooked up 2days ago to the head unite (no amp on them). I have a Jensen VM9214 7" touch that I also got from sonic electronics. Lil distortion when speakers are up real loud but nothing serious. Highly recomend these speakers.

Disappointed in Rockford Fosgate Primes

September 20, 2010

I am sorry that I bought these speakers for my car. I bought them because of the size - fit was important. But I should have been more careful. These speakers have no middle or base tones. It is all shrill highs, to the point where they actually hurt me when I listen at times. Ouch! Maybe its the materials (Mylar cones?), or maybe the size (too small), or maybe I'm asking too much for the money (less than $100.00/pair)? But the OEM are almost better. And that is not saying very much.

these things get the job done. they are greatly balanced, and they also get loud without any distortion. not much bass but that's because its a 5 inch sub. but overall great speakers. the built in crossover is amazing. helps to make the car look stock. i will purchase rockford next time :)

Not the greatest

September 13, 2011

Well i bought these speakers. They were not my happiest purchase. In general I just found them to sound like garbage and they are not very loud. But I will say this I ran them at about 3 times their rated power, and they lasted for a good three months. And they actually sounded pretty good. So pretty much I feel you can get better with the money.
