Oh coolIf longevity isn't a concern. The Balsa shown is likely for R/C airplanes.
So one can build speakers, and with the leftovers make a small airplane too
Seems that the majority of people here prefer sandwich wood.A good quality 1/2" seven ply will work for a small project. Lowes, Home Depot sells partial sheets.
It's good that I consulted with people here.
It made MDF go out of the available options..
Thank you all
