This morning, Loudspeaker Designer Jeff Bagby, from Kokomo, Indiana (Howard County) passed away after having been hospitalized with pneumonia on March 9th. A 60-year old man from Howard County was also confirmed to have passed away to COVID-19 today after having been hospitalized. I can't confirm if these two people are one and the same, but it's a great loss for our community nonetheless.\n\nJeff designed the Continuum, which was his take on the classic BBC monitor spec, but far more modern:\n\n\n\nthe above is the Salk-constructed version. The design was also available as a kit. Jeff designed various speakers which many have made here on Audioholics\n\nhttps:\/\/forums.audioholics.com\/forums\/threads\/continuum-build.107913\/\nhttps:\/\/forums.audioholics.com\/forums\/threads\/jeff-b-testarossa-tmm-2-way-raal-satori.94755\/\nhttps:\/\/forums.audioholics.com\/forums\/threads\/who-doesnt-need-more-speakers.86029\/\n\nand this was his Kairos 3-way, a very high-end piece:\n\n\n\nAs well as the Salk Pharos\n\n\n\nand Salk Archos Open-Baffle:\n\n\n\nHe also designed a good chunk of the enclosure design of the Salk Soundscape, those passive radiators were his idea.\n\n\n\n\nAnd some constant directivity style kits, such as the Zephyr-12s below:\nand the Maximus-12s:\n\n\n\nAnd his own DIY pair of towers named the Rubicons, one of my personal favourites just from the aesthetics:\n\n\n\nAnd he also wrote this outstanding article on a key aspect of measuring drivers\n\n\nFinding the Relative Acoustic Offset in PCD (1).pdf\n\n\nalong with other endless information he's shared with the loudspeaker community. I carefully utilized this information when I designed the speakers linked in my own signature, and he shared friendly PMs that helped make that project happen.\n\nFinally, his various excel worksheets, most notably Passive Crossover Designer and Baffle Diffraction Simulator, became a staple of DIY loudspeaker design. They are available on his page:\n\nhttp:\/\/audio.claub.net\/software\/jbabgy\/jbagby.html\n\nRIP, Jeff:\n\n\n\nThe community lost someone great, today.
