To be clear the sub I am having issues with is the RW-10d. So if this fix doesn't work, which should be comparable to it? I have all reference speakers right now, and when the sub worked everything sounded great. I was thinking of the R-110sw, or maybe the R-112sw, I just dont know if I need a 12", since the 10" was powerful enough. And, will it last? I mean mine was purchased in 2006 brand new, and I havent ever really pushed it, not to mention that since we had my daughter I have barely used it at all, and she's 2 now. So, from 2006 to 2013 it was used lightly, since then it was used even more lightly and rarely used at all. I just don't want to spend money on a sub that will crap out in a few years again.
