I made some traps to tame the highs behind my Martin-Logan SL3's. I got 6 swimming pool noodes and covered them with material from the company that supplies tube traps (silent source - link from the tube traps page) - the noodles are bubblegum pink. I then attached 3 tubes to the wall behind each speaker with velcro, spacing them about an inch and a half apart. I have fournd that they smooth out the strings on symphonic works - they sound more rounded and fuller. I think I need to add at least one or two noodles behnid each speaker. Next project is corner traps...gotta find something better than chicken wire, though. I was thinking of noodles placed in a ring. secured to top and bottom wood end caps using dowels, and stuffing fibreglass in-between, then using the same material as before to make a tube sock. Any thoughts ?
