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.
