Hi everyone, I am new to the forum. Recently got a ML Depth-i Subwoofer for a project. After opening the sub for further trouble shooting, found out the amplifier board is totally fried! Corrosion on the board everywhere! After calling the ML service dept, I had the feeling that they are NOT going to do anything.....no parts, no suggestions..COVID-19 excuses.... So, I am thinking if it is possible to find an internal amp board that is compatible to the sub? I think the power supply is still good? I have no knowledge in circuit stuff and only know how to use the multimeter to check voltage and connectivity🙁😕 Correct me if I am wrong....power supply to amp board to crossover to sub cones? or is it possible to use an external amp to drive the sub? Thanks in advance for all the inputs and suggestions!!🙂
What is the approximate power needed to drive the think acceptably well? Or the rated by the manufacturer?
This value is by far, far from my actual knowledge of of-the-shelf amplifiers. Try search in ebay or the like for a ready-to-use board.
You'll lose the servo control of the cone if you swap in a 'normal' amplifier which would be a shame. I've heard the Depth it's a great sounding subwoofer. Remarkable really for it's size and 'only' 3 x 8's.
