Axiom Audio Ep500

I like the fact that the EP500 system offers phase control of 0 or 180 degrees. It even has five crossover points of 40 Hz, 60 Hz, 80 Hz, 100 Hz, or bypass, if you're using the electronic crossover in your processor. It's nice that the EP500's trim knob provides the ability to overcome room loading or boundary effect. The subwoofer is also available in multiple finishes and grille colors.
