I’ve followed Mr. Leon’s posts on the Lii Audio Facebook page for quite sometime. I’ve 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. I’m thinking about experimenting with curved wings that would follow the outside curve of the baffle, and would be 3/4” x 5 1/2”. Lowe’s has material for this made out of polyurethane. What do you open baffle folks think about this? Would I be wasting my time?

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! I’ll definitely check out more of his videos.

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