I think Larry is surprised, and I know I was to find that bass drivers run flat only to 60 to 100 Hz and then roll off. As you said about the Altec 414, lots of mid bass, little deep bass. The 414 was more than 10 dB down at 40 Hz. But the acoustic bass "E" string at 42 Hz just booms out of the speaker. Now Stereophile, as always, says full range means output dowjn to 20 Hz. But they never say how much? So when using WinISD and watching the output plot, how many dB can the driver drop below "flat" and still be a "bass" driver?
