It was designed to use 3 inch midrange speakers in separate PVC tubes, and to use dome tweeters. Currently I have found no 3 inch mids that have better specs than the SAMMI copper voice coil 3 mm Xmax speakers at any price. There is no other dome tweeter that can be configured to be as close c-to-c as the Dayton Neo (and I'm not going to ribbons since I don't like their sound, nor can the lowered distortion on eight ribbons match that of 30 domes). While I could upgrade the amplification hardware and go from an analog electronic crossover to a digital one, I'm not sure that this would be significant enough to be heard.

So.... while I look for items to upgrade, I've not found any yet---at any price.
