BASSHEADLIFE DEMO KINGS 2018 RULES
Bassheadlife proudly presents: Demo Kings
A completely new style of competition that takes the art of Demo's to mind
The Following is a complete layout of the rules
1- The meter will be placed in the center of the passenger glass with ONLY drivers window down or driver door open. If door is open then all windows are up. You may choose to run either way, window down door closed or window up door open but not permitted to change during testing. Doing so may result in a disqualification. If the door is open you may however swing it out or in more to find that sweet spot.
2- You may sit in the vehicle and hearing protection will be provided if you ask but not required.
3- You may select a passenger for you run. 1 Passenger per available seat. ALL occupants will have the choice to wear ear protection and provided by event judges or staff.
4- Your score will be determined by TERM-LAB MAGNUM equipment and placed by qualified person selected for the event.
5- Your Maximum SPL will be recorded and limited to no more than 30 seconds. You may play ONLY music. Everyone will have 2 runs at the meter. The Highest Maximum SPL will be recorded of the 2 rounds.
6- In the event of a tie then a tie breaker will be held. Persons in the tie breaker round will be given 1 minute to play music or tones of choice for Average SPL count. The best Average 1 minute SPL will win the tie breaker. Other contestants will be ranked according to tie breaker position.
Rules are subject to change. Visit the rankings page to see current Demo Kings leaders and scores.
(Subject to Change)
Demo Kings will not be running a clamp just yet. Make sure to read the special notice for Demo 1-4 at the bottom of the page
The Newly Revised Demo Kings Classification will be broken down into 2
groups of classes.
Demo 1-4 will be based on a combination of cone area and total rated
subwoofer amp power.
Demo 5-7 will be the Wall classes, based only on cone area
Demo Unleashed – No limits, true ultimate/NHB class
These classes will be based on the total metric cone area (see chart
below) and total RATED subwoofer amp power.
Demo 1: 3,300 Aggregate
Demo 2: 6,500 Aggregate
Demo 3: 10,000 Aggregate
Demo 4: 20,000 Aggregate
To find your classification, find your cone area from this chart, and
add it to your total RMS amp power. Whatever class this number falls
under, is what class you’re in.
(1) 12 on 1 2000w amp, 730+2000=2730 Agg, is in class Demo 1 (Agg
limit under 3300)
(2) 15 on 7500w, 1140 x 2=2280, 2280+7500=9780, Class is Demo 3
(6) 10s on 2500w, 3042+2500=5742, Class is Demo 2
What this does, is level the playing field between those running a ton
of cone area on relatively low power, vs a TON of power with very
little cone area
Simple cone area limit, no mods forward of B pillar (such as wooden
roof, built out dashboard, etc.)
Demo 5: 3500 cm2
Demo 6: 7000 cm2
Demo 7: 7001 cm2+
No Holds Barred, True Ultimate class. Anything goes.
***NOTICE to Demo 1-4 Power ratings. Your amp power rating will be determined by OHM load and how you are wired. If your running a 1 ohm amp and you wire lower, then a % of that will be added to your power rating. We do not calculate for rise in classification. So lets say you are running an amplifier rated at 3000 watts at 1 OHM and you are wired to .5 OHM. You will be classified as a 4500 watt power rating. Demo Kings recommends wiring at your rated ohm load. We will be checking OHM loads at the amplifier for classification. And we will be going off the manufacturer ratings for all amplifiers in Demo 1-4
