Alesis M1 Active 520s

Recently one of my speakers has lost all high end and just sound real low and flat.
They approx 5 years old, never been red lighted or mistreated.

I tried to open them up to see if any caps have blown or fuses are needing replaced. How do you open these monitors up?

Any ideas, solutions, diagnosis?

Please help if you can
