Speaker Specifications

Series
This is the manufacturer product line of speakers.
Type-R (Alpine)
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.
6" x 8"
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.
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.
Santoprene 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".
89 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).
63 - 28,000 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.

No
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 or millimeters, required to contain the speaker.
5-1/16 x 7-1/4 
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.
No

Solid Performer!

November 30, 2013

I installed the SPR-68 in my 2014 Mustang GT. At first, the bass was lacking compared to the factory speaker, but after several weeks of "break in," the bass improved. The balance between tweeter and midrange is good considering there's no outboard crossover. The ability to aim the tweeters was helpful in creating good staging across the whole dash. In fact, without time alignment or other processing, the sound stage is well outside the cabin and above the hood! Tweeters do not attract attention to themselves and blend in to give more realism than the factory speakers did. Eventually I will use a 120-W/ch amplifier to drive them instead of factory deck power. I expect they will sound even more dynamic. You will definitely need a subwoofer(s) to get the bottom end of the spectrum but that's to be expected with a small 6" x 8" speaker. Quality of the composite basket and surround are top notch. Neodymium magnet keeps the speaker very light which is appreciated in an already heavy door. Installation is simple after cutting off one of the extra mounting tabs. Would suggest that Alpine include a foam gasket to seal basket to the factory mounting location. For the price, it's hard to go wrong with these speakers. In the future I may compare them to the Polk MM570 but for now, my focus will be on adding subwoofers to see how everything works together as a system.

Overall great speaker worth the price

May 20, 2014

Used these to replace the taxi cab speakers in my 2012 Boss mustang. Installation was easy but be sure to buy the metra pigtails if you want to use the stock ford speaker wire harness. Look on line to see how to take your car apart without damaging your car. The speakers do not have a grille and the speakers would look good if they could be seen. Clarity. Is very good and there is a significant difference in sound quality over the stock back speakers. Fit was very good. Expensive but worth it especially if you want to expand your system in the future.

These speakers are a great replacement for the factory speakers. I used these on my 2007 mustang and I must say that they are pretty impressive. They aren't expensive and they aren't bad quality. I would highly recommend this to anyone who is on a budget and are looking for some speakers that you get good bang for your buck.

July 26, 2013

I had these in my back doors and if you are looking for very powerful midbass at a good price you can't beat the type r's. I didnt like them though because they made my door rattle too much so i returned them for RF t1 components and I couldn't be happier. These are great speakers but its all about preference for what type of sound your going for.

Great match with an alpine head unit and small alpine amp made for the head units..

February 6, 2013

The 50 watt (i think) rms Alpine complementary amp that goes as a piggy back with their head units, really spices these speakers up.. I put 4 of these in an 06 Mustang with Shaker 500 subs in the door... The sound is amazing.. Everything a normal person would need.. The highs and mids are crystal clear, and thanks to the shaker subs, the lows are there too.. I have the gain at 50% and turning the head unit to about 70% will cause your ears to ring from the volume.. and it stays clear! Love it..

I purchased 4 of these speakers to replace the stock door speakers in my F150 about 6 months ago. I would highly recommend them. They still kick just as they did out of the box! You will also notice an incredible increase in sound quality alone. I paired them with an Alpine Type R 10" sub and together they blend very well in my truck.
