Thanks, Doc. BTW I used to watch the original version of Dr. Who.
The speakers are only going to be used as playback speakers primarily. While we could move them for other purposes, it is not my intention to do so. The keyboard is used for playing melodies, chords, and for tuning, not for performing. I mean, I'm a drummer. What more can you expect from me.
My thought on the PA bit was to simply tie into the speaker wire and only use it when playing something on the keyboard and turning off the amp for playback.
So can I run the LaScalas through channel "A" and the KG4s through channel "B" and play both at the same time and get a little more highs(which I can do)? Or should I just adjust the treble/bass and enjoy what I have. They do sound great. Even without the tweeter. I was listening to "Salvation Is Created" today and it was simply great though those mamas.
