MB Quart MB 280 loudspeaker

A new name to me, West German company MB Quart GmbH is, in fact, the reincarnation of the Peerless loudspeaker company that until 1983 used to be owned by New York–based Electro Audio Dynamics (EAD). The company has been in existence for over 20 years and under either name has an excellent reputation for its drive-unit technology, MB being one of the first manufacturers to offer an OEM metal-dome tweeter. Their 1" titanium-dome unit, for example, was featured in Dick Olsher's Dahlia-Debra DIY design (footnote 1), and I became quite enamored of the effortlessly clean nature of that speaker's treble.
