Our Dutch SPL Categories are slightly different from the U.K. rules.
We only use the PD scores, the highest score will count double (peak).
We use other classes because our Dutch locals like to compare measuring like this:
Class BB1 = 1 woofer (single 10")
Class BB2 = 2 woofers (up to double 10" or a single 12")
Class BB4 = 4 woofer (up to four 10" or double 12" or single 15")
Class BB6 = 6 woofer (up to six 10" or four 12" or double 15" or single 18")
We have no power limit at our wall class!
And we have time limits: 30seconds time to score per frequency....
60 seconds to prepare for next frequency.
