[QUOTE="hispls, post: 8800882, member: 614752"] No it does not. The sub "sees" the output impedance which for anything besides a tube amp or some theoretical designs not used in commercial audio amplifiers is nearly a dead short. The "breaking " effect on the cone doesn't come from the amp it comes from the woofer's coil and the magnetic field it is in. Take a coil and drop it down the gap of a motor and it'll plunk right to the bottom. Now short the coil leads and try to move the coil quickly through the gap and you will feel a good bit of resistance. You may be able to verify this by just pushing on the cone of a woofer with a soft suspension with and without the leads shorted. This is what low output impedance accomplishes to put the breaks on the cone and "control" ringing. [/QUOTE]
