Hi I read you got some new speakers, congrats! Did you place them where your exsisting ones are in the pic? Aren't they allot larger?
Minus K is the way to go for your TW, when doing such look at only placing your table on it and not your motor. You will need to have something made for under your motor so to bring it up to the same level.
You will most defiantly be very happy if you do this.
