Standard compression horn tower speakers have a horn in the center of the woofer resulting in a less efficient performance. The decrease in efficiency is due to the gasket used to seal the gap between the woofer and the horn. This gasket adds weight to the center of the cone negatively impacting the cones performance. The gap in the center of the woofer also reduces effective surface area which means the woofer moves less air, less air means less output. By using the bridged tweeter array, Memphis has freed up significant surface area on the cone and reduced a great deal of weight from the center resulting in a significant boost in SPL.
