Newbie here with the first of many questions to come, I use 2 KSW 10 subs for my home theater / music room and one is starting to crackle from the bass. I have played with the controls to find a sweet spot and not satisfied between the movies and music, the front main sf 2s work like they should but lack bass so my two options are either replace the 2 speakers or buy 2 new subwoofers. I looked online to find replacements with no luck and would like to replace both to equal them. Thanks in advance for suggestions Any suggestions? Has anyone replaced the speaker in their subwoofer?
