Speaker Specifications

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.
6-1/2"
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.
Ring Radiator
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.

Not Specified
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 Cross-Rib Glass Fiber Cone
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.
Butyl 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".
90 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).
35 - 60000 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
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.
2-1/2"
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches or millimeters, required to contain the speaker.
5-9/32" x 5-9/32"

Good sounding, but a bit pricey (Followup review)

December 19, 2010

The reviews I read about this speaker had me believing I would be transported to a Sonic utopia where I sit on a velvet listening chair and have beer served to me from a diamond encrusted, platinum tray by a bikini clad Katy Perry, in open-toe stiletto heels. Needless to say, that did not happen. I was initially disappointed in the speakers sound, and after trying everything, decided to remove the factory grills that covered them. Presto. PRES-TO. Night and day difference. Those inferior factory grills were blocking much of the sound. These have a detailed, realistic sound, albeit a bit on the bright side (I believe the vast majority of automotive tweeters are made this way purposefully ). The woofer however, seems to lag behind the tweeter in refinement. There isnít much bass or midbass in it, and while 6.5 inch components arenít meant to produce bass, it could stand to use a little more oomph in this department. These crossovers are a thing of beauty,( unfortunately the Bozos I hired to install this stuff took the easiest route possible for themselves and placed them in a hidden locations)The crossovers have actual heat sinks in them much like a small amplifier, and high quality parts throughout. I havenít adjusted them yet, due to the difficulty in accessing them. Pros: Really neat looking crossovers that look like small amplifiers. There is enough metal and capacitors in them to give an electronics nerd multiple orgasms. The tweeters sound terrific. Cons: A bit pricey, woofer doesnít sound as refined as tweets.

You can do better for less money.

November 29, 2010

My first impression of this speaker was ghastly, the sound was hair-thin, shrill and bodyless.( Even despite the 100 Watts I am feeding each speaker from a Kenwood X600F amp) I immediately went to work on the tone controls of my brand new head unit (the Kenwood X794). After going through every ridiculous parameter on the head unit, and turning the amp gain all the way up, I managed to get an acceptable sound from these speakers. These speakers can play pretty loud. Overall impression, I am disappointed that this is what passes as a great sounding speaker in car audio circles.(Judging from the stellar reviews on this and many other sites and car audio forums). While these speakers certainly ďcrankĒ, I guess I expect more in the areas of realistic sound and detail retrieval for Alpines flagship component speaker. While I have not tweaked the crossovers yet (the clowns that I paid to install them made sure to place them in areas that are not easily accessible) I doubt it will make a huge difference. I am also convinced that the head unit (another piece of equipment that was rated highly by every site I visited) may be partially responsible for the lukewarm review. Something I could do to considerably improve the sound is bridge the channels on my amp to feed the speakers exponentially more wattage. Generally speaking, feeding speakers greater wattage tends to make the sound more life-like and helps with detail retrieval. However, the problem is I wanted to use the remaining channels to power rear speakers, and I didn't want to spend more money on another amp. Suffice to say, I will try bridging the power anyway. My friendís $200 Boston coaxials being powered by less wattage actually have the goods on these components in overall sound quality (GAG). Despite this, these speakers trump the Bostonís in the area of bass and loudness (a small consolation). If I had to do it all over again, I would but the Boston PRO60 SE components instead.

Good product for the money

November 12, 2009

This is an okay overall component system. The woofers bump nice and get great sound out of them but I was expecting more from the tweeters. The tweeters are clean and get loud but they don't let you hear the distinct sounds that a higher end tweeter does.

GREAT QUALITY SOUND

May 21, 2012

Great product. Bought few months ago. After a few weeks they just kept on playing better and better. The tweeters are the best out of these components. Clear sound at all volumes. I have a sinfoni amplitude 90.2 and it just sounds amazing!

January 27, 2011

These speakers are unbelievable! I think your problem is that they just aren't getting enough power, I have an alpine pdx 4.150 and these speakers scream! After 5 min I have to turn it down no matter what. Annnd your speakers are the best part of your system. Upgrade your amp and you will see the true power of alpine

Great Audio!

July 20, 2011

This component system was a great value that produces a great sound. The crossovers were easy to install after i made some minor fabrication changes to my front doors. The instructions for the crossover configuration were easy to follow as well. i have now had these installed for about two months and no problems so far. Would recommend for anyone looking for a higher line component speaker.

Decent speakers

June 30, 2011

I bought these speakers a while ago and let me say that in a car with horribly sealed doors they have given great mid bass, I would imagine if they were in a good door, you could have a decent amount of bass with just four of these. They offer good variety of tuning options. In my opinion you would want to bi-amp or at least use a 4 channel amplifier and power the tweeters separate from the mids. The reason for this is that I believe the mids receive more power than the tweeters and get overpowered early when you power them bridged.

Great Speakers

December 9, 2010

Great speakers purchase 2 sets of them for front and rear doors. Nice crossover with plenty of different configuration for maximun hearing quality. You can Adjust them with 6 different types of settings on the crossover. SONIC had it in a good price comparing to other site that were selling it for almost 700 dollars a set, can't go wrong purchasing from this website. Everything came in a factory packaging brand new, I have read that this product is discontinue who knows if they will be able to get some of them again. Overall great product for a nice sounding system.

Crisp, clean and clear

November 30, 2010

I replaced a pair of focal KP165 components with these, very nice, clean, not quite as much bass but a much easier speaker to listen to, the tweeters are not nearly as harsh, much softer. Much more comfortable to listen to at elevated volumes. Would definitely recommend

Genuine Product - Amazing Delivery

March 5, 2010

I just received my TypeX Pro's yesterday ... my amplifier is still in the mail. This is 100% genuine product. The crossovers included with these are incredible. For anyone wary of purchasing from Sonic Electronix, put the feelings aside. If the product description says "in-stock, ships same- or next-day," they aren't kidding. These amplifier shipped same day, speakers shipped next. I will return to SE for MANY more car audio purchases.

SIMPLY THE BEST!!!!!

January 7, 2010

Okay, I haven't heard the $5000 Focal Utopias Be-s yet...but if you are an audiophile, you'll definitely love these speakers. I've owned and heard a lot of different speakers. I have Focals 165 in the rear, and I have to say, these speakers are just better in terms of clarity and tone. But make sure you have a decent sub to go along with these speakers.

July 23, 2008

Very smooth tweeters compared to other speakers I have owned ( Boston PRO60's , Focals , etc) Crossovers are very adjustable using different plug in modules to allow for speaker placement and primary listening position (if required) I am running them from a PDX 4.150 and they sound very clear and detailed up to very loud levels. A well constructed quality speaker that doesn't break the bank.
