Another thing people it's good to be aware of, is that the power ratings on modern active speakers are a bit misleading.
The QSC K12, for instance, is rated at 1,000 watts, which is technically true.
But it's got two matched 500 watt class D power stages- one for the woofer, and one for the horn.
There's no way that even a high-pitched instrument like a violin is ever going to push even 250 watts through that horn under normal operating conditions.
If you're sizing a modular PA with this type of cab, it will sound much smoother and nicer than conventional passive speakers.
But when it comes to maximum dB levels, it's better to think of them as having roughly half to two-thirds of the rated power.
