Klipsch and Capacitors

Probably not on that model as the only electrolytic cap is on the woofer.

I'd play them for 200-300 hours and then consider updating the tweeter diaphragm's (Titanium?) if more clarity/less bite is desired.

After that maybe the crossovers starting with air-core inductors.

Buy them  - they are fun.

I had a thrift shop pair maybe 20 years ago and they sounded good with my  Bottlehead 3 watt amps as well as an old NAD 20 watt receiver.

I didn't have low stands so I put small blocks under the fronts to angle them up (probably not ideal, but they sure filled the living room with sound).
