Google Fletcher-Munson Curve or Equal Loudness Contour.
Ah got it. Totally makes sense. Before I read your post, I was curios so I used SPL meter and ran 100Hz and 50Hz and 30Hz and found that even though I had a 10dB curve, there was a 5dB difference b/w 100Hz and 50Hz (50 being ~5dB lower) and 30Hz was like 8dB Lowere. Wowwwwww. My House curve had 100Hz at 4dB hot and 50 at 6dB hot and 30 at 9dB. To make 50dB produce same spl as 100Hz, I had to bring 50Hz to 11dB and 30Hz to 16dB
. Tried it out and wasn't too crazy about how it sounded.
Round 2: Changed to following
30Hz = 13dB
50Hz = 11dB
100Hz = 4
Muchhhh better. I mean really good. each gun shot was shaking my shirt a bit
. Then I finally changed it to the following
22.5495 = 13
30.6893 = 13
49.5316 = 8.4592
80 = 4
100 = 3.64454
138.907 = 0.999999
Watching with above House Curve is a loottt of fun. Bring BOSS in the mix and it gets AMMAAZING. I know
mentioned many times in his last video of chest slam that its the house curve that does the job mainly. While I do agree with the statement, I still think that the kind of subs used also make a difference. I my case, I used to use Mini Marty with UXL18 driver and they were awesome when it came to pressurize the room but they didn't hit the bass as sharp. Don't get me wrong, they are very very good subs but it was lacking a bit of that super sharp bass hitting in the chest. There is lots of that in Tron movie. Compare that with Devastator Sub. Devastator Sub can hit very sharp bass right in the chest but lacks that low bass that Mini Marty offers. But, these Devastators also bring weird feelings which I think is due to particle velocity. They also sound very brutal. I mean really really mean with very clean and sharp bass. Finally running them 13dB hot with 30Hz doesn't really make me think that they are missing much in low bass area. But no matter what I did with Mini Marty, they couldn't produce as sharp bass as these Devastators do. I mean I had even tried 16dB and they would make my hair jump but the would still lack the punchyness. Not with Devastators though
In the same room these two subs performed differently applying same EQ. Clearly each sub has its strength. I do agree with him with the point that most think they don't have good subs and mostly its because they are running their subs flat.
What these Devastators can do is quiet scary. Running them with above curve can really catch your attention
