WIDOW MAKER SERIES Open Baffle Speakers

Widow Maker 3 open baffle speaker

HISTORY

  Welcome to the world of box less Audiophile speakers!  All speakers started out this way. Open. Simple.

For several reasons along the way various configurations of the closed box came to dominate speaker design.  For many years boxless speakers, also known as Open Baffles were rare. 

  

Thanks to advances in materials and crossover design theory, Open Baffle is back better than ever!  

Manzanita Audio Widow Maker Series of high performance, value priced Open Baffle designs are the culmination of years of effort.  Each offers an unbeatable combination of neutral full range music reproduction incorporated in the smallest practical package, All feature efficient engineering at a very competitive price.  Thinking and designing outside the box.
