BASS BOXING
-
FORMAT OVERVIEW
IASCA BASS BOXING
is a type of SPL competition (sound pressure level) using full range music as the
main judging criteria. Bass Boxing pits several competitors against each other until one competitor
prevails as “Champion”. It’s a true test of how a system performs in every day applications.
The Qualifying Round
is a 30 second round. Competitors are allowed to use
any approved,
commercially available music
. IASCA
Judges, using an approved SPL meter, will register the average
SPL score during that timeframe. All competitors compete in the qualifying round and the top two
contenders with the highest average SPL score in each Bass Boxing Division will move on to the final
rounds.
Final Rounds
-
Rounds 1, 2 and 3
pit the top two competitors against each other in an all out, full
range musical SPL competition. In these rounds, competitors may once again choose any approved
commercially available music. Each Round has specific criteria; please read the General Bass Boxing
Rules on the next page for details. These rounds will also last 30 seconds each and the Judges will
register the highest average SPL score during that timeframe.
In all Bass Boxing competition rounds,
the full range of music (
not
just bass) must be heard
cleanly
and clearly by everyone
, including judges and spectators, so the goal is to build a system that sounds
as loud and good outside as it does inside!
If this format of competition sounds like fun to you, you’re absolutely right; it is! As a matter of fact, it’s
fun for everyone because anyone with an amplifier and a subwoofer can compete in one of our several
Bass Boxing Divisions. It’s also fun for the spectators to see these cars perform, so put on your BASS
BOXING “gloves” and have a great time with us .
QUALIFYING ROUND
The QUALIFYING ROUND will determine the top two competitors in each Division;
only
the top
two competitors
in each Division will move on to the final rounds. NOTE:
Event hosts have the
option of offering as many qualifying round runs as they want to; some event hosts may only offer one
round due to time constraints.
HOW TO QUALIFY
-
The competitor has the option of whether they wish to have the vehicle’s doors
open or closed during qualifying. The competitor has two minutes from the time they enter the
competition lane to get ready to compete. The round lasts 30 seconds during which time the
competitor’s highest
average
SPL score will be recorded. When all qualifying is complete,
only the top
two competitors
with the
highest average SPL qualifying score
will move on to compete against each
other in the Championship Fight.
The CHAMPIONSHIP FIGHT
The Championship Fight consists of three rounds where the top two qualifiers go against each other for
the Title of EVENT CHAMPION. Each Round has certain criteria that must be adhered to; please read
carefully:
ROUND 1
-
In Round 1, the competitor
must
compete with the vehicle interior sealed from the outside.
However
, the crowd must be able to hear
full range music
outside of the vehicle while it is competing.
During Round 1, vehicle openings (such as windows, doors, trunks, hatches or any panel) that when
opened allow speakers to play music to the outside, can be opened
as long as the interior compartment
remains sealed from the outside.
The use of external speaker pods, or opening panels that house
external speaker pods, is also allowed. The competitor’s highest average SPL score after 30 seconds
will be recorded.
NOTE:
When panels are opened to expose external speaker pods, the system, pod or
vehicle cannot allow any ventilation from the interior of the vehicle to outside in Round 1 of competition
(closed door round).
ROUND 2
-
Round 2 is the same as Round 1, with one exception. In Round 2, the
driver’s side
front
door will be opened to 24 inches. A jig will be used to ensure the door is opened to 24 inches. The
competitor’s highest average SPL score after 30 seconds will be recorded. Competitors are not allowed
to try opening and closing the door during the competition run, in order to achieve a higher SPL score.
ROUND 3
-
Round 3 is again the same as Rounds 1 and 2, with one exception. In Round 3,
both
driver
and passenger front doors will be opened to 24 inches. Competitors may also have any other panels
opened if they choose, but they are not allowed to try opening and closing any of these panels during
the run in an effort to increase SPL. The competitor’s highest average SPL score after 30 seconds will
be recorded.
DETERMINING THE CHAMPION (WINNER)
The Champion (winner) will be determined by adding up each competitor’s scores from Rounds 1, 2 and
3 then dividing that total by the number of Rounds to arrive at an average SPL score for all three rounds
(Qualifying Round is not included). The competitor with the highest average score for all three rounds
will be declared the Champion.
