Busted Polk LSi9 worth keeping?

Last summer I purchased a set of new LSi9s. Loved the sound for a set of bookshelves. However the low load put the heat too high inside the right cabinet and actually overheated a portion of the crossover. The drivers are not damaged and still play in fact. But now I am considering whether or not to have skiing ninja build me up a set of crossovers to replace the cruddy Polk ones or just press on and let a local vintage shop give them a quick fix in exchange for in store credit on records. Immediately following the overheat, I replaced them with a set of HSU Research HB-1's and have been generally happy, but they miss a little in the 80-250hz range. The polk's dominated that range and I feel like just pressing on towards a nice set of M-Lores from Tekton. Any Advice?
