If you have monopole speakers and want to see what dipole sounds like then try this. Get your self some Lexan (plexiglass that bends) and cut out a two pieces that are the same hieght as your surrounds. Make sure you leave a 1" wide tab at the top that is the length you will need to wrap it around the top of the speaker. This is so you can attatch it to the speaker. Put a 7 degree bend in the middle of the Lexan, lengthwise. Attatch it and you have dipole speakers. It does work, and if you want to just try it out, then fold a piece of card board and tape it to the speakers. Let me know what you think.
