Atlantic subwoofers have a well-deserved reputation for power and impact without sacrificing detail and articulation. Their subs never fall into the “one-note boom” trap that is so common among conventional subs,

One big reason is this: In addition to the normal “compressor-limiter” distortion-reduction methods, Atlantic has developed special circuitry that actually eliminates the deleterious effects that the enclosure itself has on the sound. Atlantic calls this Clear Filter technology, or CFT. That’s why other subwoofers, regardless of their power ratings or their limiters, can’t match the sound of an Atlantic subwoofer for detail and musical accuracy.
