ProAc speakers have a reputation for being relatively even in response. If you'd like to maintain that honesty I would contact Audio Envy and have them build you a bi-connector set. I believe they're upgrading their SP9 orders to SP11's. The set that they sent me was phenomenal and more even inĀ response to the point that I no longer used my dirac correction and when I did an impedance sweep it was notably smoother.
