I own two pair of Forte's, and would concur that they WERE forward/harsh prior to my installing improved crossover networks. Some of what you are experiencing is the degradation of the stock network components, which are not the best quality to begin with, and only introduce more noise as they age.
Forte's are a great speker though, any way you cut it!
