I mentioned in another pervious post that my Quads and Apogees sounded very clear at "whisper" levels. What I didn't mention was I had to be 12 inches from the speaker to appreciate it, lol.
I just came back after spending an hour with the Tympani 1D, this time with a Radio Shack SPL meter. I started at about 80 dB-SPL, then incrementally turning down the volume until I reached the point where resolution would begin to fade at my seating position 17' away. When I came to 50 dB-SPL, there's still no sign of any fade. The sound is still crystal clear at 50 dB-SPL. Problem is, I've reached the lower limit of my SPL meter's range so I can say with some certainty that resolution above 50 db-SPL is still fine. Now 50 dB-SPL isn't anywhere near whisper levels. Room conversation is generally around 60 dB-SPL. And if I were to whisper at you, you would have to come within 10" from me to hear what I'd be saying. I listen to a lot of live FM broadcasts usually in the evenings. No real issues here.
