My first question is what does it mean to "undercut" the window?  My second question is about a Berg i have.  It is a 105/2 M.  The sound up high is good but the mid and low range is barky and does not speak well.  I am guessing this has mostly to do with the baffle.  Does anyone have experience working on Bergs with some advice on how i could even out the sound throughout all registers?  Maybe if i take the baffle down a bit that would help?  Thanks

spots, etc., it's probably not responding too well.

Take a look at the Wyman paper.  It is a large pdf file on the Yahoo Mouthpiece Work site.

See the dicussion around fig. 46 and fig. 60.  "W:C" in fig. 46 is "undercutting".

Discussion on fig. 45 talks about lengthening the window a little.
