Rythmik Audio on The Intellectual People Podcast

Great share..thanks

Good to hear from the engineer who revolutionized the subwoofer world...

Love my Rythmik subs

Brian Ding of Rythmik Audio has a business and design relationship with Danny Richie of GR Research. Danny has long been a proponent of open baffle loudspeakers, including woofers. His business caters to the DIY market, offering loudspeaker kits for those who can build their own own enclosures (though Danny also has relationships with woodworkers who cut MDF enclosures as flat packs, the consumer then needing only to glue the MDF panels together and paint or veneer the box. Those woodworkers will also do the build for you, including the finishing, if you prefer. For a price, of course )

Danny heard about the new, patented servo-feedback woofer system Brian Ding created, and contacted him. Danny had the idea of combining open baffle woofers with the Rythmik Audio servo system, to create the world’s first and only open baffle dipole servo-feedback woofer. The two men put their heads together, and both companies sell the paper-cone version of the F12 woofer and the open baffle 2-driver sub. Danny sells only the 12" sealed and open baffle subs, Brian those as well as his aluminum cone models, in many variations (8", 12" 15", 18", 15" dual-opposed, some models in both sealed and ported versions).

Having established all that, here is video Danny Richie shot in which he goes over all the controls on the Rythmik Audio plate amp, explaining how to use the controls to blend the sub with loudspeakers:
