Возвращаясь к амплитудам пиков.
Накидал в симуляторе 3-х полосный кроссовер Линквитца-Рейли 4-го порядка.
Получилось что-то такое:
   

Частотка выглядит так.
   

Подал на вход 6 разных WAV файлов. Благо LTSPICE умеет это делать.
Анализировались первые 2 минуты левого канала.

Для входа и каждой из 3 полос симулятор считал значения RMS, Peak to peak, Махимум и Минимум на этом 2-х минутном интервале.
Выглядит это примерно вот так:

Результаты естественно очень разные, но видно что в некоторых случаях (например 6-ая фонограмма), пиковое значение в полосе может даже превосходить исходное пиковое значение.
За 100% считается уровень 1В

Если кто-то захочет поиграться сам-файл модели прилагается. Без исходников WAV файлов есесьно. Долго аплодить.
