There are way too many associated variables to warrant an absolute answer. A perfect speaker for one person's application might be unlistenable to someone else and his application. Maybe that is why there are so many choices and so many different approaches. Exclusive of the cost, if there were a perfect speaker, there would be no need for any others.
Speakers - Your "Safest" Choice
Hello All: Many of us have limited access/ability to audition multiple speakers brands. That got me to thinking- If one had a budget of $20K max, a solid state amp rated at 125WPC, and listened to all varieties of music (primarily rock, pop, folk), what speaker(s) would you be most willing to recommend to that person and feel confident they would be happy with the purchase?
