40 watts is fine for the 90db JBLs. If you want higher sensitivity you should take a look at a Klipsch!

Speaker Recommendation
Hi guys, I'm looking for some stereo floor-standing speakers that pairs well with a 40 watt per channel (into 8Ω) otl amp. My plan is for them to be mixed use between music and movies. My budget is around 1000-1500 dollars; I don't mind if the speakers are new or used. I'll be sitting around 10 feet away from the speakers. I'm using an avr as a preamp so I may decide to add a powered subwoofer as well. What do you guys recommend?
