Hello, I'm a another ignorant noob with a question, but I promise one day I won't be a noob anymore. I have a pair of Samson TS50 Tripod PA speaker Stands and I'd like to know if I can adjust the heads to place my pair of BEHRINGER Truth B2031A Studio Monitors. The stands have standard 1-3/8 inch pole receptacles (to insert in the PA speakers) but my Monitors need a flat base to stand on. Is there some kind of adapter for the pole with a flat base? How can I do this? Should I bee doing this in the first place? I rather not have to buy a pair of monitor stands If I can put these to use. Thanks a lot!
