Speaker Installation And Acoustic Treatment Workflow

Use one sheet for each door, panel, speaker location, and revision. Preserve the original baseline and record every treatment as a specific physical job.

Stop And Correct Before Reassembly

Material Job Reminder

panel resonance      → damping / bracing / joint repair
trim contact         → clip / clearance / decoupling / preload
airborne transmission → barrier + flanking-path control
cavity reflection    → compatible absorber
speaker boundary leak → baffle + gasket + opening control
water exposure       → drainage + shield + durable materials
