MB Quart DWG 304 12" Subwoofer

subwoofer with rigid aluminium die cast chassis. Specially designed for designed for extremely small enclosures. Dual voice-coil. Coated polypropylene-cone with large roll rubber surround. Spring terminals to fit large wire gauges. Powerful but compact-sized magnet system with protective Discus-red rubber cover.

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 excess energy and ensures the sound quality of the tweeter even at extreme sound levels.
