Raising resonant frequencies of a new build
Initial frequency analysis of this D28 copy (done with a temporary 35g bolt-on bridge and the back plate taped on) is VERY LOW. Main air resonance 83.5hz and top monopole 156.6. It's standard Martin scalloped X-bracing with a torrefied Adirondack top. Since I can still easily access the bracing, I'm thinking of going in and laminating wood on top of the X brace to stiffen it. Other options would be a very light bridge, though I'm not sure how much I can reduce it or how much effect that would have. I'm not real eager to enlarge the sound hole. I was planning to thin out the perimeter of the top, but that doesn't now seem wise.
As-is, it seems like I'll be creating a real bass boomer. Monopole mobility currently calculates to 21.7.
Any other options/advice will be greatly appreciated.
