I got a miniDSP and a UMIK-1 to play with, and I'm baffled why a flat bass response, as in the bass is as loud as the rest of the frequency spectrum, sounds so weak? The subwoofer FR in my listening position is flat from 40-120Hz within 2dB (new sub is coming on Monday).
If I have a flat FR, when I listen to some songs with a lot of bass, and watching my SPL meter, the bass notes are about 5-7dB louder compared to the rest of the music. The song I'm playing for this example is DJ Snake's Turn Down For What because this song has a strong sustained 41Hz note throughout the body of the song instead of most songs where the bass beat hits once a second or so, which would mess up with the SPL reading if the meter is not quick enough to show the burst in SPL. The main music is playing at around 65dB.
However, if I put this song through Audacity and plot a frequency vs energy spectrum for the entire song, I see that the 41Hz note is around 30dB louder compared to the midrange.
Here's the spectrum for Turn Down For What
According to Audacity, most hip-hop/rap songs have bass 20-30dB higher than the mids and highs. On flat, the bass sounds really weak. If I bring up the sub volume so it is 20dB higher than the mids and highs, just like Audacity's spectrum, then it sounds a lot more normal, and a lot closer to "flat". But really, I want another 6-10dB more on top of that to really get that bass in music to sound exciting and powerful.
Does anyone know how much louder the bass beats are compared to the rest of the music? If I have a flat FR, shouldn't the bass on that song be around 30dB louder than the music?
