The Evolution series represents our latest, greatest approach to subwoofer design. Using the same engineering expertise that delivered our popular Cub Sub, these Episode Evolution Series Sealed Subwoofers deliver tight, punchy bass. They are the perfect complement to our Episode Speakers and Soundbars. An efficient DRiVE digital amplifier is combined with LFEQ Technology to deliver extended bass response with more output than anything in their class. Add in a piano gloss finish and flush-mounted grill, and it’s obvious these subwoofers deliver premium performance you can see and hear.
