Creating a diffused sound field for rear channel surround has become critical to mimic the array of speakers along the side and back walls of a traditional movie theater. The new AIM Cinema DiPole does this in a very elegant format. Each speaker has two 5 ¼" drivers and two 1" dome tweeters placed 50 degrees off-axis from each other. Two switchable settings allow the speaker to operate in either a bipole configuration or in opposite polarity as a dipole to create the desired null at the listening area. In the second position there is a circuit to boost bass response, which would normally be lost in the cancellation through the opposite output from the two woofers. The drivers are mounted in a baffle that has been carefully molded with graceful curves and angles to avoid any sharp reflections. The result is a piece of acoustic artwork that is impressive in both its style and its performance.
