No positive approach , you can make only worse, Upgrade you speakers same brand to high end line
Crossover and Wiring Upgrade
Has anyone upgraded their Sonus Faber crossover, internal wiring, and binding post? I'm a cable and amplifier believer as not all cables and amps sound the same. Using that same mindset, I believe that upgrading the crossover and internal wiring would also yield positive results and keep in my speakers longer versus upgrading.
