Hello all!
I'm building a dipole speaker and bought two open backed BG Neo3PDRs and they work fine but apparently the Neo3W works better in a dipole configuration.
So, my question is if someone else has tried to convert a Neo3PDR into a Neo3W by removing the felt on the side of the driver? Say using a toothpick or maybe it is glued to the driver?

Do you mean the felt on the round "mounting adapter"? I'm not sure "removing the felt", makes much sense though. There were some postings around here on a waveguide configuration that did though. Or maybe your dealing with a Neo3 I have not seen yet. None of mine have any felt on the driver itself.
Nope, rather the stuffing on the outer parts of the diaphragm inside the frame. This stuffing dampens the high frequency output of the outer parts which is great when used monopole. When used dipole this doesn't work as well as the CTC distance between the front and the back is increased thus pushing the dipole peak down to 7-8 khz which isn't that nice. Without the damping the driver has less off axis response at 10 khz and above but no dipole peak thus fairly uniform dipole response.
But in the end it didn't work well to remove. On the front of the driver it worked great but on the back the stuffing was glued so I ruined the driver trying to remove it (the diaphragm got loose). So if anyone wants a Neo3 to be used dipole it looks like the best option is to buy a selaed Neo3W and removing the back cover.

Ahhhhh,......"Thaaat Felt"
I have a plethora of them, "Neo8" that I'm experimenting with.
We seem kind of limited in what we have to choose from in ribbon drivers.. And these seem to be rated and thought of about as highly as any other currently manufactured ribbon type driver that I've seen.
And "POOF", That light bulb just winked on over my head again.
I have noticed how roughly these seem to have been made. I am not trying to "dis", anyone but, The work is just sloppy. I am wondering just how well I could do myself. I've taken apart Infinity "EMIT's" and they were surprisingly simple but well made
And I do just happen to have all this carbon fiber fabric just laying around. A few gallons of the epoxy for it. Enough neodymium magnets to levitate a large car. Ok, "A ......large.... clown car". A line-source I've been playing with of my own design. And enough machining experience to choke a North Korean dictator.
Would anyone around here happen to have a decent design?
Or at least a few theoretical idea's/concepts that I could work into a ribbon transducer?
Besides, you can see in the pic what happens when I have too much idle time on my hands because I am bored.
