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 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.
300 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".
99 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 - 25000 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
Hi-Res Audio Compatible
This feature refers to if the product is capable of Hi-Res Audio (HRA) playback.
