Skip the meter. Play music with good bass at the volume level you care about the most. Because the perceived loudness of bass is volume dependent, while meters are not. Also the level you get with a meter is only good at whatever frequency is playing. Your ears on the other hand will balance and average it all together. Meters cannot do this. So play music, make very small adjustments, and repeat until satisfied.
