TDC,
Just to clarify: I am considering cutting out only the welds and/or enough material to leave an open (damped) gap in each fin. That is what Sam P. did as well. In searching the archives here I did run into a post by someone who had cut out the fins entirely and reported no improvement beyond that obtained from just cutting out the welds and leaving a (damped) gap.I had not considered a cutting wheel for cutting out the welds. I imagine that the working room was pretty tight? The hand drill I have would probably not allow a square cut with a cutting wheel - it would have to be angled in. Were you able to get reasonably straight, clean cuts? How would you describe the resulting improvements in sound quality?
