Yes I thought the same. So I think I will need more pieces of it. (Its 127db continious and 132db peak pressure so from even 5-10m from the subs it would cause permanently hearing loss just in some minutes...)
How do you figure that?
Let's do a little bit of math. Let's use the 132dB peak number.
10M is a 20dB loss over 1M So that is 112dB at 10M. Next let's assume 15dB peak to average ratio (this is up for debate-it could be more or less)-so subtracting 15dB gives 97dB.
And if you add in (or subtract) the periods of time that the music is either not playing-or quieter periods in the music-the "average number" goes down even more.
And that is assuming you are running the cabinet right up to the edge of destruction. If you are running it with a little bit of headroom (which is ALWAYS a good idea), the max level would go down-so the continuous or "damage level" would also go down again.
So if you were to measure with a DOSE meter-it would probably be closer to 80-85dB at 10M. Not exactly what most would say would do permanent damage within a few minutes.
It would take a brave man to do a 1000 people outside gig with a pair of 132dB sub cabinets.
And if you consider that very often the subs are run 15dB louder than the full range cabinets-then that means that full range cabinets would be in the range of 70ish dB. Of course if that ratio is less-then this number could be way off.
HOWEVER-it depends on the expectations of the audience. It might be just fine. Just don't expect anywhere near dance club levels.
