Exactly, which is why broadband absorption is the best solution in most rooms. Further, peaks and nulls don't occur only at modal frequencies. Comb filtering happens at any frequency, and as soon as you move your head or a microphone the frequencies change. The only time I'd consider a tuned trap is to target a single large peak at a very low frequency. And I'd build it in such a way that a broadband absorber could be placed in front to handle all the higher bass frequencies.
