Hi Dave; I have 3 of the ASC Planar Traps and find them useful for controling high frequency reflections off side walls and other highly reflective surfaces, ie I have one in front of a large hardwood dresser and two on sidewalls. I don't think these were meant to be reflective-- they are primarily diffusors/absorbers. I assume you've looked at the pics at their website www.tubetrap.com When I bought the Planars, I requested a 4 ft. height (for aesthetic purposes), and ASC custom cut them for me (same price as the 5 ft. ones).
IMO, these are kind of fine tuning devices and are not substitutes for the bigger and more effective Tube Traps (for bass control). I also use five ASC 11" tube traps. For $150. At first glance, it doesn't seem like you're getting much for $150., but I think what the customer is paying for is design and engineering as the Planars themselves seem lightweight and kind of flimsy, but they are nice looking and effective in helping to fine tune your listening room, and I can recommend them for that. Good Luck. Craig
