Opera P15 features
You can connect the speaker cables via the locking speaker connectors. In this way, a stable connection is ensured and you don't run the risk of cables getting yanked out, since the connector clicks shut. Furthermore, the sturdy housing has been kept light and portable, thanks to polypropylene material. The speaker is easy to mount on the wall with an optional bracket, and you can choose to mount it vertically or horizontally. You can also mount it on a stand, thanks to the 36mm adapter.
