You might find this hard to believe (I was quite surprised myself), but with Boom Boom Pow running full range -- we managed to hit a very clean 108 dB measured at 12 feet (stereo pair). This was with a 150 watt amplifier. Keep in mind that this is in our extremely well damped listening room. Even at this extreme volume level, we managed to have a low volume level conversation between the 3 of us in the room and we heard each other speak with ease. This is most impressive for a pair of bookshelf speakers...
Here is that information.
