sorry couldn’t resist.
audioaural site has some basic info that may help here.
This is one of the reasons why certain songs sound way better than others with respect to bass. The building blocks of having better bass, is to make sure you have the bass frequencies in their proper positions.
Having clean bass frequencies is enough to get amazing bass through any audio system.
The bass frequencies are from 20Hz to 160Hz. The best frequencies to boost for bass in a song, are around 50Hz and 80Hz. These frequencies make sure that the bass sounds full and powerful. All bases should be subjected to a bell curve at the key of the song.
Bass in an audio track is between the 20 to 400Hz range of frequencies. The frequencies are shorter and longer when compared to the higher frequencies.
I probably missed it here, but, are you running a system with two fifteens per side? One crossed over to the other? I am confused and your question is interesting. By the way I play and have recorded bass.
