Speaker Specifications

Series
This is the manufacturer product line of speakers.
Type-S (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.
4" x 6"
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 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.
Polymer/Mica Composite
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.
140 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.
45 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).
93 - 22000 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.
1-21/32"
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches or millimeters, required to contain the speaker.
3-3/8" x 3-3/8" 
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

type s 4x6s

June 14, 2010

These speakers perform really well considering their price plus they fit in the doors of my cavalier perfectly with the plastic baffles provided. They rattle my doors with only my deck for power. First time I bought Alpine and I must say that I am impressed. You can't go wrong with these.

Excellent Deal!

October 4, 2009

Received the speakers quickly and installed them in a classic Ford Mach 1. Speakers sound pretty good, could use more base but I think that is because they're only being powered off a sony deck. Overall, very happy with my purchase.

Amazing Sound Quality

February 26, 2012

I installed these in the dash of my 02 blazer and even with 2 JLw6 12s in the back I can still hear my music with great clarity and they aren't even amplified. I would definitely suggest them to a friend!

They Make Popping noises

September 14, 2012

Second day I had these speakers they started making popping noises. Both of them are in my front doors powered the head unit. Besides the popping noise they aren't very loud. I listen to a lot of dub and these speakers just don't handle it very well. My only advise would be spend a little more money and buy nicer Alpines.

not a good speaker at all

March 10, 2012

Bought the alpine sps-406 from Sonic. Shipping was very fast. I installed them the very next day. The speakers sounded okay but after 10 hrs of playing trying to break them in, i raised up the volume and they sounded horrible. My stock speakers sounded way better than these alpines. I don't understand the big hype on these speakers. I don't get why so many good reviews. I should have saved my money. Good thing i didn't buy them for 69.99 or i would have been mad. The only good thing about the speakers is the look and the design.

Have owned these speakers for about 3 months now, and they are superb. Im glad I went with these. The clarity is unreal, and I only have them off of deck power. Cant wait to amp them up. They fit perfect in my 2003 Cavalier. Now I can listen to every kind of music and it sounds amazing. Sonic Electronix is the best too. Defiantly am and always will be a returning costumer.

Alpine Type-S speakers

November 10, 2011

The speakers themselves have a good sound quality, but they cant produce any bass whatsoever in my cavalier and aren't good with high volume. My 4x 10" Alpine Type-S in my trunk more than make up for it though. I should've gotten the Type-R's instead.
