Nemo--Darla Scene--Subwoofer Test

You need to have Finding NEMO and it is in chapter 25--Darla! (1:18:16) (I attached the waterfall chart to this too)

I just thought it might be something fun for ALL SUBWOOFER users to take part in....just something friendly

I wondered if people could take out their SPL meter and play the Darla taps the Tank scene. It has Very strong bass centered around 30hz and for the most part doesn't have too much above or below that point....

Some things I learned to be sure of when using the SPL meter.
1. Use C-weighting FAST for this peak test
2. Use the MAX button if you have a digital Meter

I'm curious about a few things.
1. db registered using C-rating Fast and MAX (if avalible) on the Radio Shack SPL Meter from Listening Position...Just post uncorrected numbers...meaning, post exactly what your SPL meter shows....
2. db from 1 meter away (this should help get an accurate reading for everyone since LP varies)
3. Room size cubic feet
4. What subwoofer set up are you running?
5. What setting of Master Volume and what do you have your sub dialed in at?
****Note....when running this test turn off main speakers if possible so you are just measuring the subwoofer output


I'll start since I just watched it again and it gave me this idea

WOW cool....never knew anyone did this.

Well lets do a current one here

My 105 seems WUSSY compared to some of those numbers....

That original poster says he hit 117db with Dual SVS CS 20-39s DAMN

Using a Digital SPL meter....72db Uncorrected.

C-weighing FAST looking for the MAX.

it would be easier to read if you could post in this format....

1. 105db from Listening Position (Digital SPL Meter)
2. 113db from 1 meter
3. 2300cuft (not sealed due to open doorway)
4. A single SVS 16-46Plus
5. Master Volume -4db Sub is calibated to 72db on SPL meter (uncorrected)


The 1 meter number is important since it can be a set measurement.........the LP measurements will be relative since everyones is diffterent...

Personally I start it from chapter 25 , Darla! (1:18:16) too

With the meter on fast you can get an accurate reading since the TAPPING happens several times over about a 10-12second span...

ps.....I did mine on SLOW....ED Mullen suggested that SLOW be used for calibration and FAST for measuring those Peaks..

Now I didn't know that, so I learned something.....Now I'll have to remeasure tonight when I get home...he said I should see 1-2-3db increase using fast

I also asked him about the Digital Radio Shack Meter....is it more accurate.....do we need to apply correction numbers to it??

For the PURPOSE of this thread DO NOT APPLY CORRECTION to your numbers....just post them as you see them on your SPL...maybe even note ANALOG or DIGITAL...

I'm not trying to be a pain But I want to create a Master list of our data.

Can we please put our information in this format??

1. db registered using C-rating Fast on the Radio Shack SPL Meter from Listening Position--Just post uncorrected numbers--meaning, post exactly what your SPL meter shows.
2. db from 1 meter away (this helps get an accurate reading for everyone since LP varies)
3. Room size cubic feet
4. What subwoofer set up are you running?
5. What setting of Master Volume and what do you have your sub dialed in at?


My Example...
1. 105db from Listening Position
2. 113db from 1 meter
3. 2300cuft (not sealed due to open doorway)
4. A single SVS 16-46Plus
5. Master Volume -4db Sub is calibated to 72db on SPL meter (uncorrected)

Then I can just copy and paste Items 1-5 and make a cool master list for us. I have this in other forums too with others already responding in this format....so I can take data from everyone and just copy and past for us


TO MAKE IT EASY FOR YOU......just copy and paste my information and just change the numbers to fit your data....that should take like 60seconds...

Sweet....give me a report from the various positions....Its cool if you have 2-3-4-5 sets of results...Once you post them in the format I'll copy and paste them to the master list

I'm really looking forward to seeing what people report

Eli are you willing to report on Darla on your system?

Actually once we get tired of DARLA. I'm going to start some other ones using the same exact format.

That way we know what we are posting!


AWESOME VIDEO!!!! 123db....what kind of SUBS DO YOU HAVE??

Dr. MDpain......i'm adding your information right now THANKS

Hey man this thread looks like it will be going on for a while I'm glad we are taking interest in it. Whenever you get a chance post your data and I'll update the list
