Seriously, can you have too many speakers?
Think of the possibilities...you could have everyday speakers, bedroom speakers, den speakers, HT speakers, laundry room speakers, garage speakers, holiday speakers, son-gets-invited-to-medical-school speakers, outdoor speakers, portable endodontist speakers, bathroom speakers, etc. etc.

Surely, 17 to 20 speakers should be in every household! I can establish a national adopt a speaker society to find homes for orphaned speakers in need of a little TLC.

C&C speakers are rare birds. Best luck with your search.
