By reducing excessive low-frequency energy reaching the loudspeaker, it increases power handling and improves long-term reliability. When using the protection unit pro, cerasonar recommends combining the loudspeakers with a dedicated invisible subwoofer for optimum system integration and low-frequency performance.\u003c\/p\u003e\n\u003cp\u003eWhenever a compatible DSP amplifier is operated with the appropriate \u003cstrong\u003ecerasonar factory DSP preset\u003c\/strong\u003e, no additional protection unit is required. Loudspeaker protection is already integrated into the preset, which also optimises tonal balance, low-frequency performance and supported technologies such as Dynamic Bass Enhancement.\u003c\/p\u003e\n\u003cp\u003eThe protection unit pro is therefore intended for installations where a cerasonar factory DSP preset cannot be used.
