what a coincidence, I thought today of this Idea

maybe you can take this design to maximum if you make the rear half of sphere perforated, so the rear wave goes free through it, and the front wave slides back following the sphere shape, something like this if that can function?!

I have a very large plastic fiber outdoor planter from target. Must be close to a half sphere with straight walls at the top. It was inexpensive and would be easy to cut. Maybe a good mockup for testing. I think it would fit an 8".

WOW
nice stuff ! do you currently have distribution in north america?
you obviously applied the concept to tweeters and orb speakers are packaging their drivers in a sealed sphere this makes me really interested in seeing what the results would be in an open baffle concept with a fullrange driver

Are talking about something similar to a Gallo design?

are those open back or even partially open my interest is in trying to reduce diffraction effects of the baffle while retaining the characteristics of an open baffle

Hello, they are not open in back. In fact I have heard the larger higher end multi driver systems by Gallo and was unimpressed, hence another reason I DIY. Mark Audio 12P's in OB'S.

Turk 182,,
So the objective is to leave them partially open in the back? Wouldn't that be giving rein to the backwave coming in quickly and causing phase cancellation?
