The best sound I can come up with is not a sine wave, but a triangle wave. The triangle wave creates a very nice upper and lower shelf frequency that you can both hear and feel. The bad thing with triangle waveform is that it sounds more electronic, there's some noise and its not as clean and smooth as a sine.
I struggle to reproduce this effect with a sine wave and I don't understand why. What is the special thing I need to do to cause a sine wave to rattle my tables?
If I crank the gain up too high on the bass, then compression kicks in and the bass sounds terrible, thick with no harmonics whatsoever, and will not rumble anything, even with the main volume cranked up.
If I lower the gain, it can start to rumble with better harmonics but then I can barely hear the bass.
How can I create a sub bass that sounds loud and has a powerful rumble?
