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. Herb Chong... I'm user-friendly -- I don't byte, I nybble....
