really. It's actually quite a dramatic shift, depending on how many holes and the type of foam one uses. I can quite confidently confirm your claim that the bass is affected. It's a bit 'fatter' and ever so slightly more balanced with the highs and mids than it's stock, secondary role (to the highs/mids, that is). Again ... those are my highly personal and subjective comments ... so, user results might vary.
Otherwise .... I'm just getting started.
Today I'm going to go to Home Depot to try and find a cheaper more readily available source of different types of foam. I figure material type and density will hugely affect the results of any given hole configuration, so I'm going to experiment with anything I can get my hands on.
Also going to try and device some sort of cutting template for punching out the foam circles that will cover the driver (since I'm not going to be spending 5 bucks on the Shack pads ever other day!)
Gonna stick with my medieval brass punch for the time being ... but after I finalize a material and hole placement layout that suits me the best, I'm gonna investigate making some sort of 'multi-punch' that can punch all the holes at once and in a way that the holes interact with the natural driver assembly holes.
Never had so much fun changing the way things sound.
