In my original M&K system, years ago, I used the speaker level inputs on the sub for 2 channel. Now I have been into multi chaannel for about five years and have been using the line level from the LFE output(B&W speakers,Titanic sub)to the sub. DD and DTS sound great, as does SACD and DVD-A, yet I am not getting any output from the sub when playing 2 channel SACD's. If I go back to using the speaker level inputs and the sub's crossover, I know the bass from the 2 channel SACD's will go to the sub, but will I still get the LFE output when watching movies? ANy thoughts?
