Just figured it wouldn't hurt the traffic/discussion in here to add a bit of spice by having a thread devoted to SPL (Sound pressure limit), or systems built for competition use.
Hopefully this will attract people who don't know much about the SPL community and enjoy learning!
Anything from videos of competitions you have been to or competed in, to builds you have completed of your own or for others.First lets start with some friendly information.
What is Sound pressure limit?
Sound pressure level (SPL) or sound level is a logarithmic measure of the effective sound pressure of a sound relative to a reference value.
It is measured in decibels (dB) above a standard reference level. The commonly used "zero" reference sound pressure in air is 20 µPa RMS, which is usually considered the threshold of human hearing (at 1 kHz).I'll start with fairly recent news from brazil, Alan Dante has set a new world record of 183.4 db
He achieved 183.4 dB using two STETSOM amplifiers, the25k2 at 18V and 6 DDZ 18's
This was recorded using RTA audio control that is accurate up to 190db.
Here is also a leak picture of an amp that is soon to come to America, and is a incredible monster at a stable 70,000 rms watts
Its likely that this could be the amp of choice for any teams running stetsom next year
