Tweeter Specifications

Tweeter Size
Refers to the size of the tweeter. Typically, smaller tweeters produces less output with higher frequency response.
1"
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.

Polypropylene
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.

No
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.

Yes
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.

Yes
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.
200 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".
97 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).
3500 - 20,000 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
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.
Not specified by Manufacturer
Bottom-Mount Depth
The depth when installed from the bottom of the mounting surface. Measured from the bottom of the speaker's magnet to the top of the mounting holes on the rim of the speaker.
Not specified by Manufacturer
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches or millimeters, required to contain the speaker.
Not specified by manufacturer

good little tweeter

February 21, 2014

they arrived very quickly and were a great choice for upgrading my factory tweeters in my and couple of co-workers cars, however their power ratings are overrated i managed to turn down the amp that powers my tweeters to about 50 watts of true power and they felt like they were on fire. the other 4 i got installed in my car they sound loud and crisp. running all tweeters off of a 4 channel amp running about 35 watts at 3/4 of the way up, no problems after 6 months of having them playing straigh some times for hours at a time

Great price i picked up a couple pairs to install in my car and a few of my friends cars. the pros is they add highs & clarity to your system. THE CONS if you plan on running these ONLY HOOK TO YOUR CD/or what ever stock amp. you have i would not hook them to an aftermarket amp as on 3 pairs all blew up within sec. correct ohms wattage ect. as for the 2 pairs i installed powered by my alpine cd player works great and all 4 other door and 6x9s are powered by an external amp.

March 20, 2013

Got these Tweeters about 6 months ago now and I purchased them for my car. These were very easy to set up with my current configuration in the car. I ended up mounting them on my A piller and they sound great, the highs cut right through my bass and make everything balanced nicely. Would definitely recommend these and would buy these again if I needed tweeters again.

ehh....

October 10, 2012

I bought these tweeters because of the price but you get what you pay for i guess. Dont get me wrong they sound great but after i play them for more then 15 minutes they cut out and kick back on every now and then. If you dont have a lot of money then sure buy these but im not a huge fan.

Good Product

August 21, 2012

So far product has withstand the elements of 55 peaks Watts and 35 peak watts of JVC headunit. Initially, was to have them connected to a 840w x 4 amp. (power accoustik) but installation did not happen this way due to installer error. So, can they handle the 100w rms, I don't know.....but I can say with these little bit of watts the sound is low, (db.) but sounds good with two-way sony speakers in doors. Highs are clear, but distorts with no amplifier. Not real bad distortion, but a little bit.
