HK-25 Omnidirectional Loudspeaker

youmagine

I found a unique pair of vintage loudspeakers on Craigslist that caught my eye, and although I couldn't justify buying a full-sized pair, I wanted to recreate them in 3D printable form because they were so distinctive. Each speaker consists of a top and bottom part. The bottom part is designed to accommodate a 50mm aluminum driver found in many inexpensive "iPod" speaker docks, as well as a small cut-out at the base for adding a speaker terminal. The top sets above the speaker with its diffusion cone facing down towards it, and can be attached with adhesive once you're satisfied with the arrangement. These speakers are designed to project sound over a 360-degree area. The diffusion cone has an unusual shape that I copied from the original design. I'm not sure if the intention is to give the speakers some degree of directionality to preserve the stereo image, or if the shape serves another purpose, but I tried to keep the model in line with the original design regardless - a photo of actual HK-25's is included for reference.
