A:AnswerNo one unless they trashed a speaker. Otherwise, they buy two.....Klipsch speakers are not matched as pairs as some are......so you can just get the same speaker and it will work. Isn't that great.
A:AnswerUsed to have a H/K PM660 Integrated Amp years ago. Great amp which I hope is similar somewhat to what you have. My recommendation is the Klipsch RP600M.
