Rendezvous Region Rod Run


DB Drags Stereo Competition



You spoke and we listened...

we have lowered the entrance fee for  "leveling up" to the professional category!

Though we let you entrants come up with the cost of the entrance fee at $50 in addition to the show entrance fee of $20, when show time came we received some complaints that the total cost of $70 was too high. therefore, we have lowered the "level up" fee from $50 to $30, bringing the total entrance to the professional "Level up" to $50 instead of $70. we hope this satisfies the needs who felt that the entrance fee was too high, while at the same time bringing in enough support to recover  the costs of the equipment we purchased to have this part of the show in the first place.


Also...


Because of the serious spirit of our audio enthusiast entrants in the battle of the boom,


We have now added a third category.

Along with the amateur SPL trophy, and the professional overall trophy, 

there will now be a professional SPL Trophy !

 

About DB Drags 


 a couple years ago we acquired access to a professional Audiocontrol full spectrum analyzer with high SPL capability. ( 160 DB ) This gives us here at Rendezvous Region Rod Run the ability to analyze your systems stereophonic abilities much beyond the license plate rattle from a bump in the trunk! Don't get me wrong, the DB Drags high SPL will always play a majority role in scoring, but now we have the ability to create a judges sheet that will reflect the total systems sound and how it is safely assembled and presented.


That's where you came in. We at Rendezvous Region Rod Run created a judging sheet . . . we took your input on such questions as…What percentage should . . .the DB, the clarity, the curve track, the installation, the presentation and safety . . . count in scoring? Furthermore, many will like to have test and tune days . . . how many should there be and when? Also on show day this will take more time . . . should we have it in two parts . . . part one on Friday with a test and tune day and Saturday the DB Drags . . . or somehow roll it all into one day? Given the upgrade in equipment, what is a reasonable entrance fee?


We considered your input on these questions and combined that with IASCA / UASCA standards, the intent to be reasonable, and yet improve contestant progression. and came up with the following . . .


     So here are the details as we mash down the pedal on the DB Drags Stereo Competition.  


In an effort not to leave out anyone who may just want to get their feet wet in stereo competition, the Rendezvous Region Rod Run entrance fee of $20 to enter the show will remain the same and includes the use of the previous years SPL method and a category trophy.


 However, for those who want to “level up” in an effort to professionally analyze and improve their system, the New Audiocontrol Stereo System Analyzation Competition will be $50.


Test and Tune day will be Friday at 3 PM at the “Burnout Box” on Main St.

Judges may use any score value within possible scoring range as needed.

 

Name______________________________    Vehicle____________________________

 

Staging

Defined:

Staging refers to the musical point of origination (front/rear/side placement) and how closely it approximates that of an ideal concert-hall environment. So stage presence is the ability of a vehicle to mimic the presence of live concert as if you are sitting in the front row, in theory everything should sound as though it were emitting from the hood of your car (where the stage would be) as if it were a live concert.

 Explained:

This is perhaps the stupidest category ever, when in your car, you’re not at a concert, the type of music most automotive stereophiles are listening to is not at a concert (have you ever heard hip hop/rap live? Did you just puke in your mouth a little?), and you don’t want your car to sound like you’re at a blaring muddy concert either. (No, that belt squeal under the hood is not Prince on a guitar whammy bar in “Lets Go Crazy” and that engine knock clatter is not the drums in Van Halen’s “I’m Hot for Teacher”. If you have noise that sounds like its emitting from your hood, please…go see a mechanic.  

Therefore, this category is worth a big goose egg.

Possible score 0

 

Imaging

Defined:

Stereo imaging is defined as the illusion of lateral and vertical placement of instruments across a concert-hall stage.

Explained:

This is the placement of the instruments on the stage, if we apply it to Stage presence it would be equally lame, but if we ignored the principle all together then we would be saying a muddy mess origination is okay, which its not, so as applied here Imaging is the differentiation of origination of sound, though it arrives to your ears at the same time in relation to the other sound frequencies. Think of a loud stereo system in a car that goes by you, the sound timing changes as it goes by, this is a change in imaging, but from one location. We want different points of sound origination, but arriving at the same time.

Possible score 10 20 30

 

Frequency Range and Linearity

Defined:

 Frequency Range is how closely an individual frequency segment is reproduced. Sound Linearity focuses on how evenly music is reproduced throughout the frequency bandwidth. Both having to do with closely sticking to the music frequencies as produced.

Explained:

Also known as Tracking the Groove or Tracking the Curve. Flat sounding systems fall short of tracking the Groove (or Linearity) in a given Frequency Range, and systems with excessive emphasis in a given Frequency Range extend past the Groove (or Linearity). This is also a somewhat lame category as well, here’s why, 99% of all music is not acoustic, its electronically produced (and reproduced, and reproduced), until the powers that be get the sound just the way they want it so it will appeal to the menial mass of would be listeners. Here’s the deal, you’re an individual not a menial mass, and if you have the ability to reproduce (remix) the music the way you want to hear it, why shouldn’t you? But we digress, this doesn’t mean that your system shouldn’t have the ability to Track the Grove, if you can follow the leader closely, you can probably lead the group well too.   

Possible score 10 20 30 __________

 

Noise

Defined:

Noise refers to anything that does not exist in the original program material, and is created by the vehicles electronics or the audio system.

Explained:

Not what your parents call all your music, but the engine whine, static buzz, and hum usually created by improper component and wiring installation.  

Possible score MINUS 10 20 30 __________

 

SPL

Defined:

SPL (Sound Pressure Level) is just that, the level of atmospheric pressure increase produced by the sound wave that emits from the sound origination, usually by the fluctuation of speakers.

Explained:

 This comes primarily from low frequency and not only because woofers are bigger pushing more air. Think of it this way, imagine standing at the beach in waste deep water, high frequency waves are short and close together ^^^^^^^ so a smaller wave at impact, low frequency waves are larger and farther apart /\/\/\/\/\/\/\ so a larger wave at impact. These waves need not be audible to the human ear to produce SPL, but most often the waves that produce the biggest impact are audible to the human ear, think tsunami wave crest vs. a large ocean swell. That is a rudimentary explanation, and several other factors play a role, for instance, where you are standing on the beach, if you are out to sea like a surfer you are on the wave swell before it crests and the wave might just go right by you, but if you are standing waste deep on the shore the impact of the crest of that same wave might kill you, that is high SPL.  

Possible score 160 (one per DB)__________

 

Electrical

Defined:

Proper fusing, wire-looms on all exposed power wires, grommets where wire passes through sheet-metal, covers over terminals, zip tied or otherwise fastened wires and components.

Explained

Bundles of rats nests of wire crammed in or around system components, loose unprotected wires and wobbly batteries are not just unsightly, they’re a safety and fire hazard. So unless you’re raising chickens, do something with that nest!

Possible score 10 20 30__________

 

Components

Defined:

Components are securely mounted and complement the vehicles decor.

Explained:

Many components fail because of poor loose installation, amps, EQ’s, head units, etc. should be secure. And if you like a certain amp brand and a different speaker brand, and a different source unit brand, okay, fine, but if you have three different brands of amps, your right and left meowers are different brands, with mismatched woofer grills, a tweeter is hanging from a wire, and third gear shifting doubles as a way push the head unit back in, you better be able to reasonably tell your Judge why.    

Possible score 10 20 30__________

 

Ergonomics

Defined:

  System ergonomics is how logically the system and controls are laid out.

Explained:

Do you have to open your door to adjust your EQ under the seat? Did you have to put the car into reverse to allow the head unit to open? Did you have to lean across the console and put you foot on the steering wheel for leverage to push yourself in reach of the back seat to adjust your preamp?

Possible score 10 20 30__________

 

Creativity

Defined:

  Creativity is originality beyond basic ergonomics.

Explained:

Speaker configurations beyond a woofer box fastened in the hatch, amps that are more than just screwed to the trunk floor, and preamps locations other than just screwed to the bottom of the dash. 

Possible score 10 20 30__________

 

Attention to detail

Defined:

Attention to detail pertains to presentation and cleanliness of the owner and the vehicle.

Explained:

Do you look land smell like you just woke up from an all night binge with a Sasquatch? Is the Judge going to get lung cancer just from sitting in the car with you? Is your car washed and waxed, or does your Judge now need a shower just from touching your car? Is the interior clean and vacuumed, or did the Judge have to wait for you to clear off the passengers seat and floor of cans, bottles, and gas receipts? Does your car smell like a 1960’s smoke filled bar crossed with a sweat sox gym? Are your amps fighting for fresh cool air from being buried under clothes and rags in the trunk? Is the engine compartment one spark away from an environmental oil fire disaster? Anyone can get a near perfect score here, and there absolutely is no good reason not to.
