"Eiron"


I think you will find that they
1) take speaker-level inputs
2) which are directly connected to terminals for the left/right speakers
3) via a resistive network, combine L+R and feed it to an electronic
LP filter and thence to the built-in power amp and subwoofer driver.

Please feel free to give an example of one that works your way.



** Don't ask the STEAMING GREAT IDIOT to do that.

All the useless cretin will do is post links to false and misleading
information.
