I have a small forest of Knauf sourced traps sealed at each end with wooden pie plates. My sister-in-law fashioned spandex sleeves for them. I use a mix of 12" and 18" and stack them. I placed the 18 inchers behind the speakers and the 12 inchers mid way into the room.
Empirically, they were able to vastly improve the bass linearity in the bottom couple of octaves. Highly recommended.
