Am fortunate to have 4412s & 4410s. Of course the 12s were used as mains.
But , I don't have the room to align them horizontally as intended. Somehow they did not have the magical imaging of the 10s when used that way.
Swapped them front to back, 4410s new mains, an upgrade in my setup.
PS: anyone know why the 4410 has standard wiring post AND 1/4 plug for inputs while the 4412 does not have the plug input ???
