JBL Control HST 5.25-Inch Surface Mount Speaker

The JBL Control HST 5.25-Inch Surface Mount Speaker provides a flatter resulting frequency response along with a consistent sound character throughout the room.

The patent-pending design includes a wall-facing woofer, two horizontally splayed tweeters, a wall bracket that spaces the speaker the required distance from the wall, and a tapered cabinet that provides proper loading and dispersion of the sound. With most on-wall (surface-mount) speakers, the baffle of the speaker is some distance from the wall. It is the nature of low and low-mid frequency sound waves to wrap around the speaker, where they reflect back out from the wall, recombining with the original sound. When this occurs, some frequencies add coherently to the original sound and other frequencies cancel, causing peaks and dips in the resulting frequency response and inconsistencies from location to location within the listening space. By substantially reducing this occurrence, Control HST is able to provide a flatter resulting frequency response along with a more consistent sound character throughout the room.
