METAL TWEETER HOUSING
Our new Reference 19 mm tweeter uses a metal tweeter housing. It is a direct application

of our BTT technology originally applied to our Q-Line tweeters. This new design

encapsulates the neodymium magnet structure in a specially designed metal

cooling housing. This new mechanical structure helps to remove the excess

energy generated inside the tweeter’s magnet and voice coil assembly. By

dissipating the unwanted heat into the surrounding environment, our new

Reference tweeter offers exceptional performance, improved power handling

and high reliability. We’ve even reduced the dimensions of our new tweeter

to allow it to be installed in even the smallest areas.

COAXIAL TWEETER SUPPORT
The new Reference coaxial tweeter support allows for rapid conversion of the

component speaker elements into a coaxial system. This completely new support

system offers adjustable positioning of the tweeter. By twisting the support, the

tweeter can be set to three different angles, each 45° apart. This level of adjustment

allows for the best acoustical reflection angle based upon your specific installation needs.

COMPOSITE BASKETS
Using a combination of polyamide ABS composite reinforced with extremely short

glass fibers, our Premium and Reference Line baskets withstand temperature and

humidity extremes with little, if any, reaction. The magnetic motor assembly is

added through an insert molding process, resulting in precise orientation with the

cone and voice coil. Because the basket is non-metallic, non-magnetic and resonance-free,

it becomes one of the best possible designs for automotive loudspeaker application.

TWEETER PROTECTION
A light bulb is incorporated into the Premium and Reference crossover networks to

extend the life of the tweeter by protecting it against overloading. This element

automatically absorbs excess energy (lighting the bulb) and allows continuous

operation of the tweeter even at extreme volumes.

CONNECTION TERMINALS
The solid one-piece connection terminals provide all possible connection options.

Whether plug-connected, screw-connected or soldered, even with heavy-duty twin-core leads,

the connections stay secure, effectively cutting out transfer resistance of even large-section cables.


TITANIUM DOME
Titanium was initially developed for the aerospace industry because of its superior

strength-to-weight-ratio. It is at the same time both very light and very strong.

As a material for tweeter dome application, titanium is ideal only if properly engineered.

MB QUART has nearly perfected the use of titanium over the past 25 years. Similar

to the Q and Premium tweeters, our new smaller diameter 19 mm Reference tweeter

domes incorporate a composite surround material connecting the dome to the housing.

This combination of dome materials reduces unwanted, out-of-bandwidth harmonics

and acoustical distortion. The result is an extremely smooth frequency response and

extended bandwidth for a truly musical listening experience. This is what gives
