Onhwy61 said "A bass trap is a passive device that can only dissipate acoustic energy from a room. As such it can never eliminate a null in room response since it cannot add energy into the room."
The energy is allready in the room (if your speakers/equipment are capable). The problem is a null is created when the waves come back to you and meet where you are positioned and those freq are cancelled and therefore not heard. Just the opposite of a peak where you are positioned at the peak of the waves coming together to reinfore that freq. A bass trap decreases the wave strength (reflection) and therefore decreases the null and at the same time brings down the peaks.
Onhwy61 said "But in that case you didn't really have a bass null, but two bass peaks."
So, have can you have peaks only and no nulls?
