Spiral speaker enclosure to Omni-Directional driver - Why?
For those who have never seen my work or my FB timeline - www.facebook.com/SparrowLegsSpeakerDesign/, initially I wanted to build the best audio speakers on a budget. Starting off the first construction was a sealed spiral speaker enclosure. Logarithmic, similar in shape to Bower & Wilkins “Nautilus” - Design by Laurence Dickie.
Why a spiral? Three reasons:
To test my cabinet making skills
The cabinet becomes a sealed infinite baffle in design, IE it absorbs the speaker drivers rear waves
It looks cool - “Your ears have eyes!”
Moving on to Omni-Directional speakers, this transition evolved simply due to the potential problems an enclosure can produce. Get rid of the enclosure and there’s one less link in the chain.
Open baffle speaker design has no enclosure, but this doesn’t fit in with SparrowLegsSpeakerDesign’s mantra - “ anything with a sharp edge wasn't conducive to sound reproduction”.
Omni-Directional speakers was the alternative. (Especially with the tools and materials available).
