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. Our new,

smaller 13 mm Discus tweeter dome provides a smooth frequency response and extended

bandwidth in a very small package. This is what gives MB QUART its signature sound.

COMPOSITE BASKETS

The new Discus baskets use a combination of polyamide ABS composite reinforced with

extremely short glass fibers to form the basket. Similar to our Premium and Reference

Line baskets, our new design will withstand temperature and humidity extremes with little,

if any, reaction. The magnetic motor assembly is attached via a metal flange

(another application of our BTT technology) that acts both as a cooling element and as

a protective covering to seal out dirt, humidity and temperature fluctuations. Because the

basket is non-metallic, non-magnetic and resonance- free, it becomes one of the most

ideal designs for automotive loudspeaker application.

POLYPROPYLENE CONES

The cones of the bass and mid-range drivers are made of a special mineral-based

polypropylene. This material is far superior to a conventional paper cone. This applies

to both its acoustical properties and its resistance to humidity, temperature fluctuations

and UV radiation. The result is pure listening pleasure, year after year.

TWEETER PROTECTION

A PTC protective element is incorporated into the loudspeaker crossover to extend the

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