Placing your speakers on a table or the floor might be fine for a small room with a few people. But in a large room with fifty or more people, you will need to raise the speakers higher so that everyone will be able to hear. The spreading tripod legs of these speaker stands allow you to get the height you need, while still being stable enough for large 15 inch speakers. The mounting pole has two sizes on either end for compatibility with most speakers. The included mounting bracket will fit VocoPro's PV-802 speakers as well as other speakers with screw in type mounts.
