Speaker Specifications

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.
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.
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.
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.
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.

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.
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
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).
97 - 22,000 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.

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.
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches or millimeters, required to contain the speaker.
5-1/16" x 5-1/16" 
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.
Number of Speakers
This is the number of speaker that is included in the package. Each purchase will result in receiving the number of speakers indicated here. Please note that some items will have multiple woofers in the same enclosure. For sets of component speakers, this number will refer to the number of sets of speakers (For example, 2 would indicate the purchase includes 2 woofers and 2 tweeters).

Please refer to the product image and description for further details about the speaker.

Okay for a month.

January 23, 2013

I had these for maybe a month or so they starting sounding crackly. So I got rid of them and got JL Audio 4" speakers. Way better sound quality and clarity.

Great fit for BMW x3

October 8, 2014

I had the stock, Business version audio installed in my x3 and the tiny Philips speakers were pitiful. Replaced all four door speakers with SPS-410 and the sound is 5 times better at least. The stock speakers were exactly half the weight of the 410s. Plenty of YouTube video instructions on how to do it. Changing the speakers alone was no more than an hour job. In my case it took several hours since the glue holding the door panel attached was old and dried out, so half of them came off. Keep some gorilla glue handy - it will fix them in no time. Very good deal.

Alpine Type S 4 inch

March 19, 2013

It really sucks if your car takes 4" front speakers because you cant expect much from such small speakers. But this was my case so i ordered them and they sound pretty clear and took a lot for them to distort so i was happy with my purchase. Do not expect any bass from these speakers because you wont get any nor is that what they were designed for. I now own a pair of 5.25" Alpine Type R's and they sound much better and have some bass so if your car has 4 inch factory speakers id reccomend trying to fit 5.25 inch speakers, its a big difference even though they are considerably more expensive.

Barberton, OH


January 31, 2012

I purchased my Alpine SPS-410 to replace my stock speakers in my 1995 Toyota Tercel. The difference in absolutely everything was utterly astounding. The volume, the clarity, the bass and treble. Other than its size, this speaker is exactly what I wanted. Soon adding rear speakers that are a bit bigger to the rear and cannot wait to see the results.

Very happy with these speakers

July 14, 2014

I replaced the 28 year old paper cone speakers in my 1986 Jaguar with four of these 4" two-way speakers. They're the biggest that would fit without modification. Being 4 ohm rather than the old 8's they're only getting about 10W each from the original head unit (Jaguar-branded Alpine). Nevertheless, my "system" now sounds fresh and crisp throughout the volume range and right down to the lowest frequencies these can produce, about 100Hz. So I can hear the bass being played but I sure can't feel it the way we're used to these days.

Therefore my next step is to add a head unit that can give me pre-amp out to a small sub such as the Kenwood KSC-SW11. That should be a perfect match for the Alpine SPS-410 speakers.

These sound better than my $150 Hertz speakers. They sound so good off an Alpine deck and the mid bass is exceptional.

Great Replacement

December 4, 2011

I would defintely recommend these speakers (and have many times). I had a pair of the SPS-400's that went bad under warranty and Sonic replaced them with the new SPS-410's. They have great spatial imaging, are not bright (no intense highs that are tinnny), they handle the power from my Alpine amp nicely, and the price cant be beat. I regularly post on BMW fanzines and have done many installations on the BMW X3. These fit right in and sound great.

what are 2 way speakers ?
A shopper on Jan 9, 2015
Best Answer: 2 way speakers contain a dedicated speaker(driver) for low and high frequency sounds. (3 way speakers have another one for the midrange). In coaxial designs typical for automotive speakers, the smaller high frequency driver is centered in the cone of the low frequency driver.
