I was working under the premise of trying to make the room the best I could BEFORE adding any EQ but when dealing with LF this appears to be hit or miss in terms of the value equation (cost and practicality vs. benefit achieved). How low should I be worried about if my sub plays flat to around 18Hz? Does the criteria change if I have the ability to go lower in my setup in the future (i.e. sub upgrade)?
Being that is the case, your treatment options are not limited to bass traps. Multi-sub mode cancellation per Welti can yield much more effective results than absorption.
Roger, thanks for the specific response. If you consider my room modes below, does that mean you would not attempt to tame the peak at 30Hz through absorption but rather through the addition of multiple subs placed to cancel out this particular gain?
Here is the FR of only my sub (1/24th smoothing applied to make comparison easier):
Green is with the sub in the middle front wall (under C speaker), red is right front corner loaded and purple is the same as green but with MultEQ XT32 applied.
