The problem with room modes at low frequencies is not that they are there, but that there aren't enough of them present to smooth the overall response. The number of modes per octave increases each time you go up an octave and somewhere around the 200-400 Hz or so point, depending on room size, there are enough present to finally smooth the room response. Bass trapping will always help at low frequencies if there are insufficient room modes present.Bass traps have another benefit: they reduce room reverberation time and accelerate the decay of reverberation. This helps reduce the level of reflected sound you hear fast enough to reduce or eliminate masking of lower level direct sound and clarifies the music considerably. There's a test track called the 'Music Articulation Test' on one of the Stereophile test discs that will allow you to hear this problem in your room, and you can then try comparing the results with and without bass traps. They will always be better with traps.
