Sealed or Ported Subwoofer which is better| polk dsw pro 660 vs qacoustic qb12 

Sealed enclosures reproduce the low frequencies more accurately than ported enclosures because the air inside the box acts like a shock absorber, allowing the subwoofer to move back and forth in more control. The sound waves are reproduced more accurately than with a ported enclosure but the subwoofers may require slightly more power from the amplifier to get the woofers to move as much as they would in a ported enclosure. Sealed enclosures are generally smaller and easier to build because there is no port to tune
