Had been browsing the web for good speaker designs and was intrigued by the concept of horn speakers. Thought I would go ahead and make one just to see if the claims on the web were true or not (very high efficiency, no cross over distortion, great sound in th mid range, and bass up to 30-50 Hz without woofers) . The designs on frugal-horn.com seemed well thought out and the Spawn
family seemed to be good performers especially after the glowing reviews on equivalent speakers. I was planning on recycling drivers (3 inch or 4 inch speakers) that I already had so therefore selected the least wide Spawn speakers.
The picture shows how the speakers turned out. Wife likes em! Will post a video later on.
Printed the plans
out. I needed 18 inch wide panels for the sides and 5 1/8th inch wides for the baffles and dividers etc. Closest were 16 inch wide and 5.5 inch wide. So decided to get enough of the 5.5 inch white MDF panels to make one speaker. Also bought some nice plywood and Lowes cut it for me to 18 inches wide. Was simpler to stick to the original 18 inch dimensions otherwise I would have to recalculate the internal baffle dimensions.
