Curved wings on sides of baffles
03/14/21 at 18:38:43
 
Ive followed Mr. Leons posts on the Lii Audio Facebook page for quite sometime. Ive always been intrigued by the side wings that he puts on each rear side beside the woofers. These are aimed at controlling the rear bass waves. Im thinking about experimenting with curved wings that would follow the outside curve of the baffle, and would be 3/4 x 5 1/2. Lowes has material for this made out of polyurethane. What do you open baffle folks think about this? Would I be wasting my time?

Geno,

I know enough to know that I don't know. I can pass on this video.

https://www.youtube.com/watch?v=H0dYJc9SeZ4&t=717s

I enjoyed watching Danny Richie's videos about speaker design. This one he talks about wings about 10 minutes in. I say it's worth watching all his tech talk videos.

Great video! Perfect explanation. I had not thought about varying depths of the wings. Deeper for lows and shorter as the frequency gets higher. I guess a full range driver would be very hard if not impossible to try this with.

Thank you for posting, groove! Ill definitely check out more of his videos.

I have a lot of curiosity in this area. I also have no desire to try it myself.  :D

In a full ranger application, a really aggressive scallop cut in the wing might do something desirable?

Im interested in trying this with my 15 bass driver only baffles, so I guess Id need them relatively deep (6 to 10?) I wonder how much difference itd make making them deeper on one side than the other? Experimenting will be the only way to find out.

Gene I think Mr. Leon puts those wings on because maybe one day they will fly!

I have tried wings and they do change things, sometimes for the positive.

However, all my uppers have been full rangers. That was my Holy Grail. Find a full range driver that did it all.
Tall call, that one!

So I never had any need to make the heart shaped or the baby cheek wings as GR Danny did. At least as far as I knew ...

I sometimes wonder if I have missed something along the way.

This is a good LP to use to test whether wings change things.

Ha! Out of necessity, I ended up abandoning the two separate Caintuck style baffles on each side, so that I could put both the full range driver and the bass driver in a single speaker unit. So, the idea of putting curved wings on the sides of the original radiused baffle, went away too.

So, as Riviera Jim said, they flew away Smiley

Best,

Geno
