+10 dB is perceived as twice as loud, as a rule of thumb.

more like 4x as loud

Its all from a point of reference. I promise you from 130-133 wont have the same volume increase as 165-168. Using a rule of thumb based primarily on its point of reference is kinda irrelevant imo. Thats why i just dont bother.

A lot, every 3db on the meter is 2x as loud to ear... I think thats how it goes at least. //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif
Especially when u are getting over 140dbs, 5dbs is a lot. 145 is nothing compared to a 150 to ear at least, and the abuse that you're vehicle is gonna take.

3dbs is the necessary amount for the human ear to distinguish a difference. Not double.

10 dB is HEARD as twice as loud.

3 dB is twice the Sound Pressure Level.

Neil is correct.

Thats where i had the little bit of confusion... I knew 3db difference was double something lol.

need yours guys opinion, I have a big show this weekend in madison I will be throwing about 8000wrms to the setup, TSS or Alphamax?

Lets hear what you guys think

I definitely wanna see what 8kw would do to a TSS.

Go for the TSS

Can you post a new thread with just test results, power, box, vehicle, instead of having to read through 50-60 pages? Just an idea.

 

[bumpin buick 5,000+ posts]

I will once I have them all, I just posted a page of my results, I have tons of pages. I will post it all when im done //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif hope that helps

I didn't think that it would be, but even a middle line woofer taking 6k is impressive as hell. Numbers?? And are u planning on testing out the Alphamax on the same power??
