Loudspeaker Disassembly & Repair Instructions; Amplifier Module - QSC K.2 Series Service Manual

5. Loudspeaker disassembly & repair
instructions
To reduce the number of pages in this service manual, all K.2 Series loudspeakers have been combined into one section.
The K10.2 powered loudspeaker is referenced for generic disassembly and repair procedures. The K8.2 and K12.2 models
are assembled nearly identical to the K10.2.
Slight differences between the K.2 models:
• The K12.2's high frequency transducer is not secured to the front of the baffle with screws. Instead, it's all mounted
behind the waveguide on the threaded studs with 4 nuts and 4 washers.
• There is no side handle on K8.2 models.
• K8.2 has a single port on the baffle, while K10.2 and K12.2 models have dual ports.
• The bottom rear foot is a custom shape and not interchangeable between models.
• The pole cup mounting plate is different and not interchangeable between models.
Torque specifications
Torque settings are not included in this service manual because they vary between models.
• All torque values can be found in the Exploded-View drawings.
• Each component that requires proper torque has a square box with a reference number
(next to the item number). A legend of all torque values is referenced on the first page.

access other screws beneath the rubber feet. See Figure 5.1.1.
4. Remove 6 plastite screws that secure the amplifier module to the speaker cabinet. Only remove the screws noted in Figure
5.1.2. There are other screws on the faceplate of the amplifier module that do not need to be removed at this stage.
