Exactly what I'm facing. I have an alcove about 4' by 5', 7'high behind the left side of my listening position, full of deep bass. I have tri-trapped both corners but this situation persists. As I see it my options are either a Scopus tuned membrane trap or build a resonator.
Could you give me a hint on how you went about the process? Much thanks.
