I have both GIK bass panels and corner traps and ASC Tube Traps. The ASC Tube Traps, though more expensive, are by far and away the more effective of the two. So much so that the GIK corner traps and some of their bass absorber/diffuser panels are now out of the stereo room and are in the family room with the AV system.
The workmanship is also much higher with the ASC products. I was disappointed in the overall workmanship of the GIK products, which came from the factory with exposed staples on some panels, wrinkled seams, and front decorative diffuser panels improperly fastened and bowed.
Eight 3' Tube Traps (two stacked in each front corner, with their diffuser side turned toward the sweet spot; two stacked to the outside of each speaker in the plane of the speaker fronts) made more improvement in the overall sound from top to bottom of my stereo than any component-level upgrade I've done.
Though not cheap, ASC products sometimes go on discount for show samples and clearance.
Good luck,
Steve Z
