The MB Quart 985 A is an active, floorstanding speaker that was manufactured in Germany by MB Electronic GmbH in 1985. It features a three-way closed construction, designed to deliver a robust audio experience. The speaker is equipped with dual 205 mm woofers, a 50 mm midrange aluminum dome, and a 25 mm titanium dome tweeter, allowing for a wide frequency response ranging from 18 Hz to 32,000 Hz. The total power output of the speaker is rated at 300 watts, capable of handling both continuous and dynamic sound. The speaker's design includes three level controls for input sensitivity, bass, and turn-on threshold, utilizing step switches or fixed resistors instead of traditional potentiometers, which enhances audio precision. The MB Quart 985 A is available in several finishes, including walnut, oak, black, and white, and has dimensions of 295 x 1050 x 295 mm with a weight of 31 kg. It originally retailed for approximately 8000 DM for a pair. The model is part of a series that includes variants such as Quart 280, Quart 390, and Quart 450, among others, with the Quart 985 S serving as its successor.
