Atlantic subwoofers use the same design approach in all our subs-from low-priced to high-to produce consistently realistic, convincing bass effects. Our subs vary in how loud they’ll play and what size room they’re most suited to. But our quality doesn’t vary. Big room or small, from loud to soft, the sound quality of an Atlantic Technology subwoofer is always top-notch.
