Admittedly, I have modded and damped more Klipsch models (mostly Heritage) than I care to remember. However, many other horn brands needed it to, such as JBL and Altec. Ringing/resonances from the horns/woofer frames; other resonances and distortions from the cabinets; outdated crossover components (lets be real, any speaker) and minimizing contact between the crossover boards and the cabinets. Yes, all of this takes a great design by the master, PWK, and eliminates the drawbacks of economic production costs. I am a Klipsch devotee!
Volti audio upgrades for klipschorns
I bought a pair of Klipschorns in 1982' in 2018. I did a complete voting audio replacement. In addition to converting to tubes. The replacement was more than I could believe. I will not go back. the increase in quality was more than I could have believed. I would highly recommend this conversion.
