Bass traps in the corners will remove mudiness in the bass notes but they are not a cure for no bass. Ie. Bass traps don’t make more bass, they make the bass you have better.
Absolutely agree, except in the case if the OP has to work in the "constraints" of his room placement and winds up with the only place for his listening position that doesn’t have a "null" has a slight "peak". I shouldn’t have phrased the traps in tandem with speaker placement. Appreciate the clarification!
plant caddies can work for your method of finding placement
My wife’s a total green thumb; but this idea never popped into my mind; great suggestion! My narrow-minded thinking could only picture "walking" the beasties around the room in a sea of sweat. 😆
