my room is roughly 20 x 15 x double hieght ceiling, with openings to other room s along the back wall. not ideal but the khorns never struggle to fill the space even with my modest 10watt amplifier. I spent many years on the audio merry-go-round until finding these speakers they will probably be my last. you can see my review of them if you want further insights. warm regards, tony
It's nice to have vintage and new pieces coexist together and form such harmony. Bet your Klipschorns sound the best they ever did with the new 2A3 PP amp! Enjoy.
