Ill give BK a call and ask if I can buy one of these things/devices but what do i ask for....what was the 'something'?It´s amazing how they can`t get rid of the humming/buzzing issues. Seems like on going issue for many years. Maybe it`s time re-design the amps. I was lucky no humming with my BK sub during 4years.
Tom Pearce from BK (technical guy) sent something for one member as he`s new Monolith buzzed and it stopped. I would call to BK and talk with him if it bothers you. One thing is good with BK stuff the repairs are very cheap what i have seen so even 10year old product can be fixed under 100£ possibly.
