ES speaker/subwoofer bundles are optimized for low to medium ceilings in venues that demand quality foreground music. Dance studios, workout facilities, bars and restaurants are just some of the venues where performance drives the overall user experience. Adding a subwoofer to the speaker mix let’s you take advantage of the wide-dispersion 4 inch dual cone speakers without compromising bass frequencies. Speakers can be spaced further apart with the subwoofer placed among them to add the kick that provides for a richer audio experience.
