Title: Hybrid Open Baffles with Harmonic Resonators.
Post by: Rocket_Ronny on 2 Feb 2024, 07:54 pm

I have a pair of Rythmik FM8s subs with GR Research Super Minis. Here are a couple videos for proof of concept. Subs have 4 hours, Minis about 30. Crossover is 200 hz. Still a lot of work to get things right, but a start. Room in new house is challenging, but a miracle to even have the system there, ha. Acoustic foam has yet to be put on the front baffle.

I have since raised the subs 10" off the ground with the funny things on the sides. They are Specially Tuned Harmonic Resonators that create an out of phase signal to cancel out box resonances.  :wink: They also just happen to be fantastic grab handles to move the speakers to their listening positions.  :wink:

Those sound great, the birds think so too! Feeding the birds are a must.

   Ha, ha. Putting them on stands makes them look like real speakers. Funny enough, they were a lot of work, since I built them the hard way to avoid mdf side seams.

And the Birds are well fed.
