MB Quart: ZT1-25

Ceramic Coated, Titanium Dome Tweeter

Ceramic coating helps to reduce over tones and harmonic distortions that can occur when using Titanium at higher power levels. The assures the system is producing the highest sound quality with the lowest distortions.

Treated Silk Surround

Silk reduces harsh distortions which can develop on the the surround in the transition point from the tweeter dome to frame where the surround mounts.

<3h>35mm (1”) dome on a 25mm (1”) voice coil

Creating a larger radiating area on the dome creates more output giving the tweeter a louder yet smoother sound.

Removable Phase Lens

The phase lens allows “Dispersion Tuning” which permits the listener to widen or narrow the width of the soundstage depending on the chosen mounting location. When the tweeter is installed away from listeners or pointing at a windshield, a wide dispersion is better - phase lens on. When the tweeter is mounted with direct access to the listener, the phase lens off, creates a narrow soundstage with brighter high tones. Additionally the phase lens aides in reducing harsh harmonic that can develop at higher frequencies.

External Crossover with -6/-12dB Attenuation

Fine tune the high frequency by using the -6 or -12dB pad of the location of the tweeter is closer to the ear than desired.

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 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.
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.

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.
80 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.
40 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".
88 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).
1,000 - 20,000 Hz
High-Pass Crossover Frequency
The high-pass crossover frequency can be a fixed crossover point or a variable crossover range. A variable high-pass crossover allows you to select a specific crossover point which allows frequencies above the set crossover point to pass, while making frequencies below the set point gently or harshly roll-off, depending on the steepness of the slope.

The steepness of the roll-off slope is measured in dB/octave and refers to the rate of attenuation (lowering of volume) outside their pass bands.

5,000 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.
4 ohms
Hi-Res Audio Compatible
This feature refers to if the product is capable of Hi-Res Audio (HRA) playback.
