Even with it's low sensitivity rating, it can get loud enough for normal folks listening habits without a problem. I was powering them in my garage/back patio with a Technics SA-101 reciever (15 watts) and they got plenty loud for everyone. In fact my wife kept asking me if I had it loud enough, being a smart-ass of course. 10 watts gets these thigns a bit over 95dBs...with plenty of excursion to spare for transient peaks. What kind of SPLs are you looking for from a 5" driver? Sure they are spendy compared to the Tang Bands...they lunch the TBs in every aspect if you ask me. Not trashing the TB shere, they are great little speakers for the money you pay for them indeed. But now compare them to the Jordans, which are twice as much. They perform as well, if not better some seem to think...at half the cost. Very nice indeed.
Just my thoughts, to each his own I understand....
