I use a 8183 for the front speakers connected to the pre out from my surround receiver.
The idea is to experiment with the addition of a center connected to a 218 which is connected to the pre out of the receiver.
Off coarse it would be nice to control the volume of the 218 with the 818, AI told me to "Connect the SpeakerLink Out from the 218 to a SpeakerLink Input on the 818v3" would that work without damage or is there a better way?

Some Meridian...
