The bottom speaker in the top portion of my L1 Model 2 is having a buzzing/fuzz sound that can be heard mainly on clean guitar/vocals/low-end bass. We tried different cables, running a T4S and a T8S, and going straight from guitar into the analog input but the sound remained. We began to take off the 4 screws on each side of the top line array and it appears to be glued down or extremely difficult to get off. Rather than attempting it myself, I had two questions.
1. What are the exact type of speakers that are in that model?
2. How do I go about getting them replaced or fixed?
