Did some more work on the system. I found that the kick panels are FAR better places for the tweeters. Moved them down there, got the TA dialed in, and it sounds MUCH better. Have the xovers both set at 2k Hz. Seems to blend very, very well. Not nearly as fatiguing as it was with them in the a-pillars. Just needs a little EQ'ing now, and it should be great.
