Default Array wings -- needed with active equalization?

The holes are cut and I'm ready to get serious about my open baffle array. It has 12 NSBs and 32 Dayton 3/4 inch tweeters a side. I have a question about the wings everyone seems to be using on their arrays -- do I need them if I'm going to actively equalize the arrays?

Wings are not "needed"...but, since they extend the dipole cancellation path, wings can provide considerable reduction in boost/cone excursion/driver distortion. If curved or angled to the rear they also impact diffraction for any monopoles in the system (like tweeters).

Imho, the "wings" are necessary for optimal frequency response.

If you read Rudie Blondia's website you'll see what the effects on the
response are from the wings... there is no effective means to correct the response due to diffraction effects, which is what you get with sharp edges and "wings" that don't do the right things...

EQ will only effect the response in the axis which you measure - assuming on axis, then the polar response (the response everywhere else) will be "wrong."

So, it's best to get the optimal results from the physical configuration, and hopefully not need any EQ, or very gentle EQ if any...

Thanks! The mid-domes are Dynaudio D-76AF. (The others are W26, W22, OW-1)
