"For system designs in which an automotive audio amplifier DSP architecture doesn’t account for a specific loudspeaker protection algorithm, digital crossover filters placed after the limiter block in the signal flow allow to mitigate the risk of a potential transducer failure due to loudspeakers operating outside of their designated bandwidth at high excursions. Considering a real-world automotive audio system use case with given filtering resources and defined DSP flexibility, this paper discusses various choices for crossover parameters selection and distribution in the system in relation to the limiter block (before and/or after). The impact on loudspeaker bandwidth and crossover behavior is evaluated for several filter-design parameter changes, at varying reproduction level: such analysis considers subwoofer, woofer and midrange loudspeaker cases, eventually leading to a best-compromise design approach."
