HQaudios Restoration & Testing Process

Before Restoration

• After decades of service, the Klipsch Heresy III speakers require careful inspection before restoration begins.

• For every pair of Heresy III, HQaudios places particular attention on the titanium compression tweeters, titanium compression midrange drivers, woofers, crossover networks, capacitors and inductors, internal wiring, binding posts and input terminals, cabinet structure, and grille assemblies. These components are critical to preserving the speakers’ tonal accuracy, imaging, efficiency, and long-term reliability.

• The crossover performance, driver integration, cabinet integrity, damping materials, and overall acoustic performance are also carefully evaluated to determine the speakers’ operating condition before restoration starts.

During Restoration

• Based on the inspection results, each pair of Heresy III speakers is restored according to HQaudios’ technical standards while preserving the engineering and performance characteristics that have made this model one of Klipsch’s most respected loudspeakers.

• The titanium compression tweeters, titanium compression midrange drivers, woofers, crossover networks, and internal wiring are cleaned, inspected, serviced, and adjusted where necessary to restore accurate frequency response and seamless driver integration.

• Speaker terminals, crossover components, cabinet seals, internal damping, and all mechanical assemblies are carefully inspected to ensure long-term reliability. Components that no longer meet technical specifications are replaced where necessary while preserving the original sonic character of the speakers.

• After the technical restoration is complete, the cabinets, grilles, and trim are professionally cleaned and detailed to preserve the Heresy III‘s original appearance while respecting the authentic character of Klipsch equipment.

After Restoration

• Once restoration has been completed, every pair of Heresy III speakers undergoes comprehensive functional testing under real operating conditions.

• Frequency balance, channel matching, imaging, tweeter performance, midrange performance, woofer response, crossover performance, and overall tonal accuracy are thoroughly evaluated to ensure the speakers perform as originally designed.

• Finally, the speakers undergo several hours of continuous listening tests through a complete audio system to evaluate musicality, soundstage, dynamic performance, and overall real-world listening performance.

• Only after successfully meeting HQaudios’ restoration and testing standards are the Klipsch Heresy III speakers approved and prepared for their next owner.
