Just about any of the models and especially the most talked about models do not need even 20 watts believe it or not.. however some of the larger woofers, or Multi driver woofer klipsch models can sometimes benefit from more power simply due to having some better current running through them for better bass output and control, but they will all play plenty loud, maybe just not as deep without the higher power amps.
Klipsch Speakers for a low power tube amp.
I have a tube amp that is rated close to 20 watts per channel, and I would like to use Klipsch speakers because of their sensitivity. Does anybody have this combo, and are they satisfied with it? I play everything on my system ranging from radio, records, and cds!
