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 various reasons over many years, several configurations of closed box designs 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 Solutions 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.  


Each of the following three Widow Maker designs have been optimized to meet and excel in their prospective design goals / price point.


Every Manzanita speaker system is a plug and play design.  Any of them are complete and ready to use.  They do not require equalizers, sub woofers, multiple amplifiers or added components to complete them.  Simply plug them in to your stereo amplifier of suitable power, set them up in your room as indicated and listen.  You will be amazed!


Widow Maker II-A is an entry level Open Baffle speaker that performs way beyond others available at it's price point.  It exemplifies what Open Baffle is all about.  Simple in design, low in cost and can embarrass speakers several times its cost.   A great, low cost way to enter the world of Open Baffle performance!


Widow Maker III sits in the sweet spot.  A critical balance of size, sonic performance, output capabilities and price point.  No wonder it is our best seller!


Widow Maker IV.  For those who must have the best, well, this is it!  State of the art drivers.  Tremendous output capability and world class bass output down into the mid 20 Hz area. What the hell, go for it!!   Every self respecting man cave deserves a pair!
