Speaker Specifications

Series
This is the manufacturer product line of speakers.
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.
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" x 7"
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
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.
1" Ring Dome
Tweeter Size
Refers to the size of the tweeter. Typically, smaller tweeters produces less output with higher frequency response.
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.

Silk
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.
Hybrid Layered Pulp
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.
Rubber
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.
300 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.
100 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".
87 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).
65 - 27000 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.

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.
2-9/16"
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches, required to contain the speaker.
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.

Alpine SPR-57C or SPS507

September 26, 2010

I went in my local electronic store & was looking for some Alpine 5x7 Speaker's. SPS507 looked like the one, But seen the Type R that had a 100 watt RMS rating and just needed to have it. So I talked them down to C$100+Tax So I got two pairs of them. On the sound board there wasn't to much of a difference in sound, Type R's had better highs then the Type S, But it wasn't fare that they were just running straight from the Deck. There Good speakers even if you don't have a Amplifier, But you need one if you want it to be louder of course. Mine will only be as loud as 18 watts RMS, I'm getting Speaker distortion around vol #25 with HPF 80Hz, Defeat on (CDA105) I can still hear them speakers over my 1,000w Sub Amp though.

Love Alpine !

September 9, 2010

i just bought 4 of these speakers and put them in a 2002 ford focus and man do they thump great clear crisp sound too! Remember to hook an amp up to these! Everything about these speakers are amazing! I've done research for awhile now and listened and worked with a lot of different speakers and these are by far the best I've listened to and worked with. If your debating on speakers and cannot decide, choose these! For the price of Sonic Electronix you cannot go wrong.

Alpine Type R

January 1, 2010

I put a pair of these speakers in my work van and the difference is incredible. I have gone from the stock 4 speaker setup to just 1 pair of the alpine's and it is now louder cleaner and more bass. Now i want another pair to see how loud and how much bass i can get.

alpine spr-57c

March 12, 2009

these speakers handled the 100wrms from my pdx4.100 amp,they didn't distort and sounded awesome through all ranges. i would highly recommend these speakers and also the type r 6.5" splits, my whole system was alpine, headunit, subs, amps and speakers, i had 100wrms through all 4 speakers and 500wrms per sub (2) it was enough to give ear piercing pitches and heart jolting bass, my roof flexed close to an inch with this setup in my suv.

Best 5x7 on the market

April 10, 2008

The title says it all. Best on the market pound for pound. Price is awesome. Great highs, great mids. You should most definitely amp them though makes a world of difference. I have mine running to a Rockford 450.4. The pivoting tweeter is sweet. Installation is a breeze also. Recommend mostly for rear fill. Get the 6.5 components in this model for the fronts.

Alpine SPR-57C

February 3, 2011

I purchased 4 of these speakers, I installed them in my 1998 Lincoln Mark VIII. These Alpines have excellent clear sound and bass response. I have them running off of a Sundown 100.4 amp and they can handle the power easily without distortion. I listen to a lot of different music from A/C D/C, Tool, Mushroomhead, Slipknot ETC. The pricing was also very good and I received them in a short time from ordering. I would recommend them to a friend.

Amazing sound

January 20, 2011

I bought 2 of these to put in the door of my 2008 Ford Ranger. I have them hooked up to an amp that pushes a little less than the RMS rating...they sound incredible, great bass and definitely worth the money...Alpine nailed it with these :-)

Alpine The best

December 17, 2010

I bought two pairs of these speakers because I wanted to use the same size as the factory speakers in the doors of my jeep. I'm pushing them with a Power Acoustik bmf 1,600 watt four channel amp, you can here the clarity of the music at a loud volume not much speakers can do that. so all i have to say is buy them you will not be disappointed. WORD.
