I (((rarely))) post in the finished forum. But anyway, I just finished work on this theater speaker. Sorry I could not show the back of it. The refference pics I have show only the front. The speaker is a HPS-4000 speaker and It's very unique in style and design. Only a hand full of theaters have these installed. The speakers make up a soundsystem called HPS-4000, or better known as ( High Preformance Stereo ). Visit the website to learn more about it Link Comments are welcome.
