Tweeter Specifications

Tweeter Size
Refers to the size of the tweeter. Typically, smaller tweeters produces less output with higher frequency response.
3-1/4"
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.
Horn
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.

Aluminum
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.

No
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.

No
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.
150 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
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".
96 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).
2000 - 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 or 8 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.
1.50"
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches or millimeters, required to contain the speaker.
1.65" x 1.65"

I bought a pair of tweeters to replace the lousy ones that came in a set of box speakers. They work so much better and handle about 4 times the power of the originals.

These are great little speakers, I used them for replacement in a pair of shelf speaker boxes. The original tweeters were junk. I had already replaced the woofers with Pyramid 300 W speakers a couple of years ago and have had no problems whatsoever.

can you hear the highs?

January 24, 2013

Super highs amazing clear will make your ears bleed if your not careful... I've got four of these in my 03 ford f150 single cab two in the kicks and one in each door... bring on the mid bass... basically if u got the super lows get these for the super highs. only down side one of the four came with no black ring on the tweeter.

These sound great. Plenty of crisp usable high end, just eq what you want. Not sure they can really handle the rated power though, mine already are blown. These are for light DJ work or small room live stuff. They are great tweeters though.

Great bang for buck!

October 3, 2011

For the price you pay for these tweeters you can't complain. They can get a little airy and harsh sounding at certain tones, but I found that if you have a parametric equalizer you can cut out the frequency's that sound harsh.

Other than that they sound awesome and GET LOUD! I'm talking they can keep up with a 15" woofer pushing 1400WRMS.

Would recommend if you need loud highs or are on a budget and want to get close to high quality sound without paying the big price. Wish they came in black.

The Best Bullets EVER>>>>>

May 7, 2011

I grew up on this tweeter and saw the transition from the 120W version to this new 300W version. Same excellent quality, can't believe they're so cheap. I love them, I'm heard everywhere. Can't say anything bad... maybe if they were all black.

Horns over Domes any day!

November 17, 2010

Look I'm no professional, but i use this site very frequently and I've seen so many reviews from people who don't know what the hell they are talking about or what they're doing really. I have been into designing my own custom parts for my truck and installing systems for about 2 years now, and from all the tweeters I've owned or heard, these by far are the loudest, clearest, as well as value oriented I have come across. I have 2 of them a friend of mine gave me out of a totaled vehicle and these things scream to the high heavens and they are wired in series with my front door speakers, with no amp. so for the people who are only giving this product that oh they're ok bull, try them for yourself they will not disappoint you. any pyramid tweeter is your best bet unless you have limited space or if your looking to show them off. only thing it u might need to remove the resistor if its not amped or getting enough juice, trust me, they will make you deaf!

Great value, great product and good performance

May 13, 2010

I bought these tweeters to replace ones that blew out on my home speakers. I searched for value, perfomance, compatibility and reviews from others whom bought this product prior. I must say I made a wise decision buying these tweeters and also to have bought it from sonicelectronix.com. I had to modify my speaker boxes as far as making the holes a little bigger and a some re-wiring. I am very impressed and would recommend these to anyone!

These tweeters are nice and loud sounded great in my car. Only thing that was slightly annoying was the capacitor end just hanging around the tweeter making it very delicate. Besides that they are great.

I have had these for a couple of years now and I love them. I am running them off of my head unit and the sound is crisp. I plan on putting an amp to them in the future. They actually sound better outside of the car. I have used smaller tweeters but they don't offer the sound that these have. These are a must buy. I got rid of the capacitor and I am running them through a crossover network.

Hi a have a pair of theses the black version was wondering how to wire them they came with the capacitor/crossover already soldered on I have the mb quart OA600.4 wired to 4 6x9s since the capacitor/crossover is already on the tweeter can I just wire positive and negative to amp or do I need separate amp OA600.4 I'm running at 4ohms?
Desbee W on Sep 3, 2014
Best Answer: you could run a positive to the 6×9 and negative to the tweeter and put a jumper in between (8 ohm), otherwise run the tweeters off a separate 2 channel amp. (4 ohm) you can't add a coil without changing impedance
