MILFORD — Fireworks, pictured from Wheatfied Drive, were going off over Altec Lansing’s Headquarters Tuesday night in celebration of its Dec. 1 sale by Plantronics, Inc., to a Texas-based profit equity firm, Prophet Equity LP, a company spokeswoman confirmed Thursday.

The company was renamed Altec Lansing Technologies, Inc. in 1996. Production facilities are located in Dongguan, China.
