Jim,
To say the least…yes you`ll be pleased with the sound from those JAC6A’s, especially comparing them to the Radio Shack stuff.
A speaker selector will take care of the impedance matching in your system. You`ll need just standard volume controls. The Monster selector is fine and these volume controls would work fine:
