Two possibilities -- listen or measure.
Listen; you must already have recordings with reasonable bass information (<200 Hz). Select a few with what you believe to be the cleanest bass (electric or acoustic bass, low end piano or organ, synthesizer, etc.) and listen at a high/average level. Pay attention to how well different instruments are defined and whether or not there is a dominant tone, regardless of instrument. The "boom" that some have mentioned will often occur around 60 Hz and jump out at you. I'm not a fan of using drum recordings since the bass drum will have one note pitch so will not offer the differentiation I look for.
Measure; while the RS meter may not be a precision instrument, you are looking for differences, not absolute values, so it should work fine. Mount the meter on a tri-pod at your listening position and make notes of the values shown for a test disc such as the bass response segment from one of the Stereophile discs. First set loudness to your normal listening level, then note the dB for the 1K tone. Next write down the dB level for each frequency from 40 to 200 Hz. Any peak tones will be obvious. The goal is to achieve the smoothest bass response possible - the least total dB variation from the 1K baseline when adding up all base frequency measurements. I've used this method to fine tune speaker position with good success.
