WHAT'S THE LOW DOWN on (((pd)))?
(((pd))) propper droppers is the WORLDS 1st and ORIGINAL, MULTIPLE FREQUENCY SPL testing format for finding out just how LOUD your car audio sound systems can truly play Ultra Low Frequency BASS.
WHAT IS ULTRA LOW BASS?
By Ultra Low, we mean those thunderously low bass frequencies that will shake and vibrate the very ground that you are standing on, the surrounding air that you are breathing in.
Frequencies that are so low and played so loud, that you can hear and feel the effects from vehicles that are streets away.… well before you even see the source of the air shifting, ground pounding, street bassing sound machine.
WHAT IS THIS (((pd))) propper droppers SPL TESTING ALL ABOUT?
It all started here in the U.K. and we have been having a crazy time, testing car audio systems for nine years now. Our SPL Testing frequencies start at 40Hz and drop to 20Hz.
With a standardised set range of
40Hz – 33Hz – 25Hz – 20Hz – Peak
Your Peak score in the main (((pd))) SPL League is taken as your highest out of the four set frequencies that you have been tested in.
The scores that you achieve are averaged out and it`s your average score that determines your place on our leaderboards.
All the scores are taken from the head rest, which is also placed at a standardised distance from the front windscreen to roughly represent the listeners head position when seated in the car.
Is (((pd))) in any other countries then?
(((pd))) is fast becoming a very popular Bass Testing SPL format, with it now running in quite a few countries around the world.
Australia – England – Italy - Netherlands – South Africa – New Zealand
Who can take part in the competitions?
- Anyone with a car audio sound system that can play bass is welcome to take part and give (((pd))) a go.
- At pd we do not mind if your system uses cheap or expensive equipment.
- We do not mind if your system isn`t finished yet.
- We do not mind if your system is super cool looking or down `n` dirty ghetto style.
If your system can play bass then it`s welcome in the pd lanes.
