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.
