[QUOTE="BrazilianBassBuster, post: 8888927, member: 692876"] For me, it's the other way around. The pleasurable bass only happens at 30 Hz and down. I have just done a test hearing on this track: [MEDIA=youtube]CuQ4dI6kmX4, list: PL8y869KV1Ir8ks9G0avxw9XBP1WkJjedw[/MEDIA] I did it using my Sony [URL='https://www.sony.pt/electronics/support/wired-headphones-headband/mdr-xb700/specifications']MDR-XB700[/URL] headphones. The specs say it reproduces from 3 Hz to 28 kHz: [ATTACH type="full"]62737[/ATTACH] I'm also using a Fiio headphone amplifier which is currently receiving an analog input from the onboard Realtek audio device of a Gigabyte motherboard, with all equalization turned off. Hopefully, this is a reliable setup for this test. Results: At 10 Hz I can notice the vibration, but it isn't quite a "musical tone" yet. Then, with enough concentration, I can hear the "musical tone" beginning at 15 Hz. Then, starting from 15 Hz, I notice a gradual change in tone. This tone change is very mild in the beginning but becomes more noticeable from 18 Hz onward. Conclusion: It makes sense for my hearing capabilities and tastes to have: [LIST=1] [*]A 4th-order high pass filter tuned to 15 Hz (-3dB@15Hz) [*]A subwoofer that extends down to 15 Hz and if possible with a slight gain in the 18-22 Hz range.
