'House curve' for center speaker

[Droco]

I just fine tuned my recent synergy to be both time-alligned as equalised between 100-16000hz +-1dB.

I have found that I'm not completely satisfied with what I have. Should I apply a different house curve? Or?

It's a synergy using a 109x75x39cm horn with a JBL 2447 compression driver and a single 12" Beyma 12P80Fe. I'm using an UMIK1 mic ith REw and a Xilica XP4080 for EQ.
