Fluid Audio FX8 active studio monitors

Fluid Audio FX8 active studio monitors. I recently bought a pair of these from an authorized dealer. One of them seems defective or dysfunctional. When the product is functioning properly, they are wonderful. When they aren’t, they aren’t. Is there anyone else here who has had problems with the FX8? If so, have you found solutions? Were you able to have them repaired by Fluid Audio?

P.S. / please note: I am referring to “FX8”, not “FX80”. The “FX80” are a newer model, which I am not referring to.

Kinda curious of what is the issue in detailed description.
No experience on Fluid Audio otherwise.
