Frequently Asked Questions

The sub-bass control is a more gradual, gentle roll-off; it's less surgical than a shelf filter but provides a smoother, more musical low-end extension.
Absolutely, 250 watts is plenty for most club or small-to-medium stage scenarios, especially when paired with a suitable cabinet.
While limited, the single sub-frequency control provides a good starting point. You’ll likely need external EQ to shape the overall sound extensively.
