Duntech is an Australian loudspeaker maker who really had a hot hand in the 1980's with their absolutely gigantic, towering speakers.
Duntech today is the self-proclaimed "most accurate speaker" which is an odd claim. The company is not seen in as many of the audiophile salons in the United States as they once did. However there is a small but fiercely loyal following for Duntech as well as those who fondly remember their sound.
Duntech is best known for their historical product the "Sovereign". Today they make a speaker called the Duntech DSM-15 that has a claimed frequency response of 45Hz to 35 kHz, and a sensitivity of 89 dB.
