I am lucky to live near Austin, so I was able to pick up my dual subs directly from his warehouse and got to meet the owner Brian and got all the info I needed. Couldn't be happier with the service and my F-12s. That was years ago. Got introduced to them through Ascend Acoustics. They have a special relationship going. David Fabrikant, the owner, is an outstanding individual. I no longer have his raal towers since I wanted to go larger in my house of stereo, but they were amazingly good for their size, specially the bass and of course the clarity of the treble with the raal tweeters. I guess I wanted to give them a shout-out. A couple of great brands that mostly go under the radar because they don't advertise.

@jtwrace Thanks for posting this. I own a pair of Rythmik subs and couldn't be happier. Brian Ding makes a great product at very reasonable prices. I've add this video to my listening queue and looking forward to hearing what he has to say. |
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:
