The Tweeter

NVX had a unique goal when designing the X-Series tweeter to engineer a tweeter with exceptional clarity and sonic characteristics, while optimizing the off-axis response for ideal imaging. The resulting tweeter has several key design features which help achieve the phenomenal sound:

  • 29mm Silk Dimpled Dome
    • Silk provides warm, crystal-clear sound
    • Unique dimple improves dispersion for improved off-axis response
    • Wide diameter offers improved clarity and output at high volumes

  • Ring Radiator
    • Improves clarity and fidelity of high-frequency sounds
    • Prevents decoupling at high frequencies

  • Robust Tweeter Chamber
    • Provides even compression throughout the full range of excursion
    • Improves linear movement and promotes more defined treble
    • Lowers resonant frequency for improved imaging

General Features:

  • 29mm X-Series Car Tweeters
  • Power Handling:
    • Peak: 260 watts per pair / 130 watts each
    • RMS: 130 watts per pair / 65 watts each
  • Silk Dome tweeter construction offers crisply detailed highs with warm characteristic
  • Dimpled tweeter dome improves the dispersion pattern for improved response
  • 4 ohms impedance
  • High-temperature voice coil
  • Robust Tweeter Chamber helps lower the resonant frequency, greatly improving imaging
  • Ring Radiator design prevents the surround from decoupling at higher frequencies
  • Improved clarity and fidelity at higher notes reduced strain on the surround
  • Surface and Flush Mountable
  • Sensitivity: 94dB
  • Top-mount depth: 1"
  • Frequency response: 800-22,000 Hz
  • Authorized Internet Dealer
  • 1-year Manufacturer's Warranty

Tweeter Specifications

Tweeter Size
Refers to the size of the tweeter. Typically, smaller tweeters produces less output with higher frequency response.
1-1/8"
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.

Silk
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.

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.
260 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.
130 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".
94 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).
800 - 22000 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.

Can't beat them for the price...

November 3, 2014

These tweets lived up to all the hype. I really don't have a thing bad to say about them as far as their sound quality. Although, they did take a couple weeks to develop the all around smoothness they have now. The first day I did consider them just a tad harsh, but that was just the pre-break in time period. Other than that, just the size of these gargantuan tweets. Hard to find a suitable location for a stealth install. am about to purchase the 6.5" door speakers and make this house a happy home!

Great Tweeters!

October 16, 2013

I was planning on getting some tweets that list for $580. Then someone convinced me to try these. I replaced my Rockford Fosgate T5 tweeters with these, and the improvement is awesome!

Details galore, not to bright and a very natural sound, They seem well built, and look great.The best tweeters that I've owned. They pair up great with the RF T5's woofers which is the best woofer i've owned.

Cons,
They are BIG, and i had to get creative to install them.
Also they don't seem to lock into their pod/cup to easily.
