- This is mostly due to power compression effects. The speaker becomes extremely
- nonlinear at a high power level and its internal impedance increases
- considerably. Incidentally, this causes horrible distortion on transient
- passages, but it does make the things almost impossible to burn out.
-
- The 901s have the cheapest drivers you have ever seen... I would estimate
- the component cost for the units to be less than $50 total per speaker.
-
- I would go on at length about this subject (among other things about how
- the speakers are specifically designed to eliminate proper stereo imaging)
- but it would just make me mad, and you can read the stuff in the
- info-high-audio archives anyway.
