Hi there! Hope will find some help here! Question is…How to access (to disassemble) the two inner subwoofer of the HP 580. I've found the Technical Manual of the Hp 520 (I think is same disassembling procedure). It tells:
1- Turn speaker upside down
2- Remove screws
3- Remove bottom panel then remove damping material
4- Remove 4 screws
5- Low frequency transducers are now free

But…what does it mean "are now free"? Can I remove either from the bottom panel? Or only the lower? If the second option is right, how can I remove the upper transducer? From the top of the speaker? Not sure, I suspect other upper components can create obstacles...Any help?
