Summary: 


I might mention at this point that there are some speaker
manufacturers, notably B&W and KEF, that use electronic protection of
the drivers.  They have electronics inside the speaker that measure and
approximate the power handling capabilities of the drivers and activate
relays when that capacity is exceeded.  I know that MY relays in MY B&W
DM7Mk2's do not have as many problems as fuses and, although not
perfect, protect my speakers far better than fuses while affecting the
sound far less.  I agree with Phil's statement that speaker selector
switches are the pits.  I have a $1200 integrated amplifier that had
arcing across the contacts until I changed them to heavy duty 15amp
microswitches.  I believe that the disadvantages of fused speakers
outweigh the advantages.
