The Misco speaker company in St. Paul, Minn., is celebrating its 70th anniversary this year. But the company's future is uncertain — a result of the trade war between the U.S. and China.
Dan Digre's dad started Misco after serving in World War II.
"He was a B-17 radio operator and came back to the United States and married a woman with a bad radio," Digre says. "Turned out the radio wasn't bad but the speaker was bad, so he started his own speaker repair business."
