This image shows a pair of Top Speaker Wedges. They sit loosely on the top shelf and are retained at the rear by a channel which hooks under the rear section of the top shelf. They can be positioned anywhere from left to right along the top shelf. The Top Speaker Wedges are angled down at 30 degrees. The stop bar at front can be fixed thru 0-30deg.
Included with each Speaker Wedge is a 2m (78") speaker securing strap. It feeds through the slots in the side panels, underneath the shelf and over the speaker monitor creating a loop which is locked by a buckle.
