Sound quality wise there has been a lot of discussion on how the basket and the motor itself will introduce lo levels of noise that are simply attributed to the basket and motor disturbing the sound waves when they leave the cone. However, output doesn't seem to be affected at all by this. Reversing the polarity is a must so that the subs do not counteract each other. Hope this helps!
