8" Beam Mount loudspeaker System
The BB2 is a complete, beam mount loudspeaker system consisting of an 8C10PAX - 8" O.D. dual cone loudspeaker with a 10 oz. magnet, TBLU - 5W-25/70V transformer, BR8WS - round, studded baffle and two (2) beam clamps attached to a round, steel backbox. As one of the oldest loudspeaker manufacturers in continuous operation in the United States, Quam-Nichols has lived through numerous changes over the years. American made brands of consumer electronics are all but a memory, as most of the big brand names of their era are either gone completely, or gone offshore — along with their vendors. Not Quam-Nichols.
