I read the theory of servo sub and am very interested in the idea how the subs work. I want to buy the used OB servo plate amps and drivers to DIY my sub as I don't have much fund to buy new.
If you are planning to upgrade your system and want to release your used ones, please kindly inform me or email me at tien.mec@gmail.com.
