Hello everyone, \nNeed your suggestions and guidance on adding two active tweeters in my existing 5.1 home theater setup. Onkyo tx-nc646 is pushing all klipsch speakers but I would need more treble. I want to set up two additional tweeters on top of whatever I have. \nHow about I use zone2 (line out), feed it an additional system that plays only treble? Like two additional active tweeters? What options do you suggest? I am thinking of using good quality desktop speakers, feed them after reducing the bass and mid somehow? Please answer.
