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.

UHF
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.
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.
50 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".
93 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 - 35000 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.
2 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.
3/4"
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches or millimeters, required to contain the speaker.
2-3/8" x 2-3/8"

Infinity Kappa 10.9T is the best tweeter money can buy!

February 20, 2014

I had Memphis 3 inch tweeters and didn't love the sound quality. I called the guys at sonic electronix, very friendly and helpful by the way, and he suggested these tweeters to me before anything else. They are very easy to install, the sound quality is excellent, and I couldn't be happier with my purchase! Next upgrade is replacing the mids and lows with infinitys' as well!!!

Nice sound quality but not very pretty

October 31, 2013

These are high quality tweets with an incredible versatility when it comes to mounting. They sound very nice but the aesthetics are greatly lacking. I got the 10.11t's as well and they are beautiful maybe this has skewed my review. In closing if you want good quality sound for a good price I would recommend these but I'd also recommend the 10.11t's more they are 1/4 inch smaller and look great

Best out there

May 13, 2013

I have had them all and at higher volume levels, nothing sounds cleaner and has higher headroom before clipping than Kappas. I have (12) of these along with (32) 63.9is, (8) pioneer pro TS-W3002D4 and (2) Buttkicker transducers in my excursion. The volume levels these speakers are capable of with the proper power and crossovers is staggering. Its like hearing a pin drop at 200 db...

Infinity 10.9T

January 7, 2013

I have a Hummer H3 w/ the speakers very low to the floor, even thou I had Infinity Kappa two-ways in the doors, the sound stage was at my feet. I purchased these 10.9T and replaced the Hummer tweeters in the pillars. Immediately, the sound stage was ear level, and detailed. These tweeters are bright, and really highlight guitar and saxophone. I had to re-eq the whole truck based on these, but it is nite & day sound-wise. Highly recommended. Pro Easy to install w/ many mounting options Easy to connect to my system, and crossovers were appropriate Soundwise; bright, crisp, defined and musical w/ a hint of highmids mixed in Con might be too bright for some (and therefore require EQ to get right in the mix) Tweeters are not small- and although they fit into my pillars, the holes required were bigger than standard

May 11, 2012

Another great product by Infinity! I have always used Infinity products in most of my cars for aftermarket mids & highs.. These Infinity Kappa Tweeters sound amazing! I used them to replace the tweeters on the dash pillar of my SUV. I would highly recommend these to anyone who wants to add crisp, clear highs to their system.

Awesome Tweeters

April 16, 2010

These tweeters really set off my system. I originally had the infinity reference 1031T's and blew them pretty much right off the bat. I went ahead and shelled out the money for these and they've been at it perfectly ever since. I've always had really good experiences with Infinity and these are no exception. The installation can be tricky because they're 2'' instead of the easier and typically stock 1'' but it can be done with a professional look. If you're going to get component speakers, definitely get the set that include these tweeters as opposed to the reference 1031T's...you'll be happy you did in the long run.

Sound Great

March 13, 2010

As many know, Infinity Kappa's are awesome speakers. These tweeters made a huge difference. I am confident these will last for a long time. I replaced these with ten year old infinity's that were in the car. Those still sounded good but could use the upgrade. Just don't lose the allen wrench it comes with. It is a custom size. Found that out the hard way.

Very Loud

January 29, 2010

These tweeters are a very good buy. I have them in my 99 grand am and they easily outplay the other 8 tweeters i have in there. Which are spl's, and kenwood's. These tweeters are very clear and very loud. I will definitely be replacing the others with more of these. GREAT BUY.
