Dumb question..but just wondering ?????

I have a pair of speakers that are manufactured by one of the higher end companies and paid extra for the cherry finish. I have used Fornby's oil and or polish on them about once a month or so since I bought them 6 years ago. They have obviously darkened through the years and look absolutely beautiful....So, my question is....does the wood ''age'' as the years go by and add their own sound? I guess my analogy would be guitars and violins get better with age.....does the same hold true for the wood on speakers ?
