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.

Yes
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.
250 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.
125 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).
5,000 - 25,000 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.

Awsome and Sharp

March 23, 2013

These are just what my system needed. These are not for people that don't like bass they're for people that have powerful subs (semi-comp). With all the options of an amp HPF and Gain these are perfect. Power acoustic is becoming my favorite brand since my wife won't let me spend the big bucks LOL

Beyond my hearings range

December 12, 2012

Sorry but the range was to ear peer-sing for me. to much was given to the ex-stream hi end and they forgot the human ear cant even hear that high. It over powered the high end I found myself turning down the highs all the way just to control it. Defiantly not for the audio system I need.

Major improvement for small bucks

November 11, 2012

Have 98 GMC reg cab pickup. Great sound from my Alpine SPS speakers in doors and SoundStream-13 sub. But Alpines behind seats in corner pillar sounded muffled. Increasing volume to them did help create bigger sound environment, but their muffled high end wasnt just noticeable, is was actually distracting. Hooked up these little guys in parallel with existing rear Alpines, and WOW what an improvement! The sound field is SO MUCH more open. Used to have volume +2 to the doors before. Now run at +7 to the doors because these cover the rear response so well. The versatile mounting was perfect for locating higher, closer to headrest level, still out of the way, but pointing at 45 deg ang across back of cab for good L/R mix. Now that I know what a difference dedicated rear tweets can make, I would probably consider a set with silk domes for less harsh delivery if these ever go out. But Im in no hurry cause these work so well. Probably the most sound improvement Ive ever heard from the least amount of money. If these can open up the sound field in a cramped reg cab pickup, they should be even better in car with more room for the sound.

Good Tweeters!

May 12, 2012

I am running them on a Rockford Fosgate P200-2 with Jbl GTO 626 and they and a great touch to all types of music! Giving them at least 50 watts Rms all day every day and they sound great! Would buy again! The only con they have is they are a pretty tall for surface mounting.
