DUO SD
Not following the easy road, but the proper one. In pursuit of a goal that only few will ever be able to reach: horn technology from bass to high range! And the DUO MEZZO reaches it easily and implicitly, even a brief look at it will directly tell. The visual result is demonstrative, agreed. But the MEZZO’s sound stage and musical authority is equally so! We welcome you to the fascinating world of full-range horn loudspeakers.
