Priced Per Pair

Tweeter Specifications

Priced Per
Car Tweeters are typically sold in pairs so you will receive 2 tweeters for each purchase on tweeters marked "Priced Per Pair". If a tweeter is marked "Priced Per Each" then the tweeter is sold individually and each purchase you make will result in 1 tweeter. High-powered tweeters are typically sold per each tweeter.
Tweeter Size
Refers to the size of the tweeter. Typically, smaller tweeters produces less output with higher frequency response.
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.

Flush Mount
If the speaker or tweeter is flush mountable, then it can be installed flush to the mounting surface.

When installing a flush mount tweeter, make sure that there is enough room behind the mounting surface for the tweeter and magnet. Check the mounting depth with your specific vehicle.

Surface Mount
If the speaker or tweeter is surface mountable, then it can be installed to be raised above the mounting area.

When installing a surface mountable tweeters, make sure that there are no obstructions that will prevent the tweeter from being installed correctly.

Angled Mount
If the speaker or tweeter is able to be angle mounted, then the installed tweeter can be positioned at an angle. An angle mounted tweeter can improve the audible sound quality of your system.

When installing a angle mountable tweeters, make sure that there are no obstructions that will prevent the tweeter from being installed correctly.

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.
225 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.
75 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".
88 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).
1000 - 29000 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.
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches or millimeters, required to contain the speaker.
2" x 2" 
Hi-Res Audio Compatible
This feature refers to if the product is capable of Hi-Res Audio (HRA) playback.

"Hand's down" the most bang for your buck!

November 4, 2014

I Purchased a set of these for my Silverado few months back.
I've been waiting to see how far I could push these puppies before I wrote a review. First off, I have been running component sets for years because thats about the only way to keep your music loud, clear, and with little distortion. Here recently I upgraded my L7 12's to solar x's. This ment I had to drive my components harder to keep up.I try to stay at about 200 -225 watts clean (rms) for my mids an highs allowing about 2k on my subs.I keep my system crossed over thru my deck, amp and crossovers supplied with my components. This past year I've been thru endless sets of components.Not that they were cheap, but just cause I push them to hard. I blew my focals one week a month later I blew a set of high energy Hertz. Fed up, Hurt, and broke $900 later I said, "self,I just can't afford to upgrade to another set of $6-$800 component sets". I ordered a new set of 2 way type R 6 1/2's. I promised myself I would not over drive them.
Because they mount low in the doors, I still needed more highs. Well I ordered these, just knew I was asking for disaster and they would be toast wired in 2 ohms trying to match the two new sets. Getting to the point, im still rocking these babies and im driving them hard now. There about 75-80% as loud as the costly components that cost 7 times what these did.And I may blow them tomorrow for all I know.Butt if I do.For what I paid for this set up, ill just buy another identical set,its well worth the money. Thank you Sonic for getting these out as quick as you did

Elizabethtown, KY

perfect balance

December 21, 2013

Put these in the 06 Jeep Liberty 2" dash speaker location. They have a perfect balance of mid (vocals) and highs without being too bright or too flat. If you are trying to replace a mid/high speaker with a tweeter but dont want to lose any performance, these are a once a done solution due to their broad frequency response.
They do lack the mounting option of putting a screw in the center of the base. But I was creative enough so that it wouldnt matter.

recommended by my local car audio shop and was ten dollars cheaper than they had offered!

Tried and true, I'm looking forward to bettering my sound system.
RICHARD E on Aug 28, 2014
Seem ok, not sure if the RMS rating is accurate but they were on sale 69.99 and it takes a while to blow they seem to last little longer than the more expensive JL
Jake F on Aug 15, 2015
Based on specs and reviews, it feels as if these are the best replacements for an aging set of Eclipse component tweeters where one now no longer outputs volume and frequency (but not electrically blown). However, I just ordered these.
