"Subwoofer" - it's like a magic word around here and makes all of us audioholics have little dreams of black boxes that cause our walls to crack, dishes to rattle, and rock our children to sleep... from the other end of the house.

Could their magic black box deliver good bass and punch at an affordable price? Read our review to find out.\n\n\nDiscuss "Emotiva Ultra 12 Subwoofer Review" here. Read the article.
