Some SPL Tetsing results for you

Recommended Posts

I thought I`d put up some scores from different sub set ups which I have tested in my standard 2.5 Cu.ft. box - 4" Aeroport tuning to 27Hz with 1x Directed 1100d amp.

Here goes:

Stereo Integrity Baby Magnum 12" in ISO: 1ohm Load / 1100wrms

Peak= 137.0dB @ 29Hz

40Hz= 134.7dB

33Hz= 135.6dB

25Hz= 136.7dB

20Hz= 133.7dB

10Hz= 127.3dB

Total ((((Propper Droppers)))) Score = 134.1dB

JBL Isobaric: 2ohm load / 700wrms

Peak= 134.8dB @ 33Hz

40Hz= 133.3dB

33Hz= 134.8dB

25Hz= 133.8dB

20Hz= 134.0dB

10Hz= 126.7dB

Total ((((Propper Droppers)))) Score = 132.9dB

Baby Magnum 12" DVC: 2ohm / 700wrms

Peak= 136.9dB @ 46Hz

40Hz= 133.9dB

33Hz= 132.8dB

25Hz= 131.6dB

20Hz= 133.0dB

10Hz= 124.9dB

Total ((((Propper Droppers)))) Score = 132.2dB

Adassa Audio 12" Prototype QVC: 2ohm / 700wrms

Peak= 134.5dB @ 33Hz

40Hz= 130.7dB

33Hz= 134.5dB

25Hz= 131.9dB

20Hz= 131.4dB

10Hz= 125.9dB

Total ((((Propper Droppers)))) Score = 131.5dB

JBL GT4 12" Normal: 4ohm / 450wrms

Peak= 135.3dB @ 46Hz

40Hz= 133.9dB

33Hz= 130.7dB

25Hz= 129.5dB

20Hz= 131.2dB

10Hz= 123.6dB

Total ((((Propper Droppers)))) Score = 130.7dB

Here are the totals in each SPL league:

((((Propper Droppers)))) - Average Totals

1: 134.1dB - Stereo Integrity Baby 12" - ISO Configuration

2: 132.9dB - Pair of JBL in ISO configuration

3: 132.2dB - Stereo Integrity Baby 12"

4: 131.5dB - Adassa Audio 12" Prototype

5: 130.7dB - Single JBL

Peak Freeqs:

1: 137.0dB - Stereo Integrity Baby 12" - ISO Configuration @ 29Hz

2: 136.9dB - Stereo Integrity Baby 12" @ 46Hz

3: 135.3dB - Single JBL @ 46Hz

4: 134.5dB - Adassa 12" Prototype @ 33Hz

5: 132.9dB - Pair of JBL in ISO configuration @ 33Hz

20Hz:

1: 134.0dB - Pair of JBL in ISO configuration

2: 133.7dB - Stereo Integrity Baby 12" - ISO Configuration

3: 133.0dB - Stereo Integrity Baby 12"

4: 131.4dB - Adassa Audio 12" Prototype

5: 131.2dB - Single JBL

((((Outlaw Bass))) - 10Hz :

1: 127.3dB - Stereo Integrity Baby 12" - ISO Configuration

2: 126.7dB - Pair of JBL in ISO configuration

3: 125.9dB - Adassa Audio 12" Prototype

4: 124.9dB - Stereo Integrity Baby 12"

5: 123.6dB - Single JBL

You can see by the results which subs or sub set up excel at low frequencies.

You can also see which subs have a higher Peak performance

And it`s a good way to see how budget stuff can outperform or nearly match even more expensive stuff, even if you have to get two subs to do it. It still costs only

I`m pretty sure I can get them louder. :)

If they were in a standard ported box the Peak SPL score would probably be over 140dB+

But the ISO set up makes them play flatter, louder @ lower frequencies.

BTW: The scores are done with the mic in this position.

It`s the position I test in for ((((Propper Droppers))))

I have it there because it`s roughly where your ears would be when listening.

In the dB drag position I think it would be louder still.

When I get the chance I`ll test the system in the dB drag (dash legal position) just to see the difference...
