Velodyne MiniVee 8 or Sunfire HRS-10

Hi everyone, I have a Kudos C2 with weaker low end that I'm looking to add a sub to help round off the bottom.  I do 70% music and 30% movies.   I can buy locally used Velodyne MiniVee 8 for $280 or Sunfire HRS-10 for $450.  Which one do you guys think is a better investment for a small 12 x 14 entertainment room?  Is the Sunfire worth $170 more?  Thanks ahead.
