There is no single answer to this question as the best EQ for bass will vary depending on the specific circumstances and what you are trying to achieve. In general, however, a good starting point is to boost the low end around 80Hz and cut the high end around 5kHz. This will help to give the bass more presence without making it sound too muddy or cluttered. From there, you can experiment with different EQ settings until you find something that sounds good to you.
