Is this speaker a free air subwoofer or does it need a box
Answered by Polk AudioHello Weyman, the Polk Audio MM842 DVC is intended for installation in a box enclosure. I included the recommended dimensions for both sealed and ported enclosures. -Sealed Box Volume: Polk recommends a sealed enclosure between 1.25 ft³ and 3.5 ft³. -Ported Box Volume: Polk recommends a ported enclosure between 1.75 ft³ and 2.25 ft³. Regards, Polk Audio
