The watchdog agency said about 20,500 Dual-Voltage CineMate II Home Theater Speaker Systems were made in Mexico and sold at military exchanges and select stores from September 2009 through September 2012 for $600-$800.
"A component in the bass module can fail when used outside of the U.S. in electrical outlets rated at 220 volts or higher," the agency said.
The firm received two reports of the bass modules catching fire. Both incidents were in Europe, the CPSC said.
The recall involves dual-voltage CineMate Series II and CineMate GS Series II digital home theater speaker systems that were built for use with 120-volt electrical outlets and outlets of 220 volts or higher.
The home theater systems included two speakers, a bass module, a remote control device, an interface module and accessories.
The recalled systems included items with a product code of 051365, 051470 or 057971. The product codes are recognized as the first six digits of the serial number on the product label, which are found at the back of the bass module.
Consumers were advised to stop using and unplug the dual-voltage CineMate II systems and contact Bose to arrange for a free repair or replacement of the bass module.
Consumers can call Bose Corp. of Framingham, Mass., at 877-354-1004.
