What stereo system is rquired to run 12 or more speakers at thome?

Answer 1

a big one  lol

Answer 2

Homes don't generally have more than four speakers for a stereo.  If you want 12 or more there are two options.

Option 1.  Get a home intercom with a radio in it.

Option 2.  Do it like commercial buildings.  You use an amplifier which has a 25 volt output, then you install speakers which have 25 volt transformers on each one.  This way you can add as many speakers as you want.

The amplifier and the speakers are listed in the two links below.
