The XO between the mid and bass is an area to look into as the 1823's roll off steeply around 500 Hz at the bottom end, and I see the Sentry lV uses a 400 Hz XO point.
Once you get everything working, you can try getting the 1823's and ST350's in phase. To do this you can build a sled so you can mount the tweeters on top of the cab, and slide it back and forth. Reversing the tweeter connections from their normal hookup, you can set an oscillator at the XO freq., and slide the sled back or forth to find the point where you get the greatest cancellation at the XO freq. with a mic placed at your listening position. The test tones on the Stereophile Test CD will work for this if you don't have an oscillator, and a reasonable quality mic plugged into something with a VU meter will suffice. When you reconnect the tweeter normally, the mids and tweeters will support each other at the XO freq.
Keep us posted on your progress!
