Frequently Asked Questions
The DSP allows for precise control over the frequency response and driver protection, resulting in a cleaner, more consistent low-end with less distortion at higher volumes.
While it's powerful enough, its limited frequency range means you'll still need a full-range speaker to cover the higher frequencies for a complete home theater experience.
Given its power handling, a high-quality amplifier capable of delivering at least 800 watts RMS would be ideal to truly unlock its potential.
