Thanks to all. I'm in Fl so with the a/c it's usually 38 to 46% sometimes lower in the winter.You must run your A/C almost non-stop if you're achieving those levels in FL. You might want to check the accuracy of your hygrometer. Normal "comfort zone" is between 40 and 60%, above that exists high potential for mold, below that leads to static and greater potential for airborne illness. The important thing for speakers is to avoid sudden, large shifts in relative humidity, this is especially true for cabinets constructed of solid wood or plywood.
