fully active with too few channels 🙂

Servus, I’m just thinking about switching to full active. But since I have a 3 way front + sub and the Sony Radio only offers 5 channel LZK two LS one channel parts. Now I wonder which LS pair I best give a separate channel and which I can put together. The HTs and TMTs by chance FAST have the same distance to the listening position (driver side 4cm difference, passenger side 6cm). The TMT and kickers lie over 20cm apart. It is now more meaningful to operate TMTs and HTs together, as before, because the deviation would not be so great. Or would it be more important to allow the HTs own channel to precisely adjust the TMTs as they play the larger frequency range and purchase the larger deviation from the kickers? The Eton at the kickers would have a phase controller, with which I could probably align them to the TMTs. Or HT and Kicker on the sleben channel, LZK on the HT The kicker would also have a quite large deviation. But would have the advantage that the two frequency ranges are far apart and changes by equalizer would not affect both LS even in the transition range. How would you do that if you didn’t have money for a Prozi or 7 channel radio?
