Bluetooth

Portable power.
Crank it to 11.

A self-contained powered build with amp, battery, and Bluetooth — dual 4" woofers and an itty-bitty dome tweeter in a print-it-yourself cabinet.

  • Dayton Audio KAB amp + battery extension board
  • On-the-go listening without a separate amplifier
  • Same enclosure DNA as the passive builds
