I am getting back into sound systems and would like some opinions on subwoofers. Looking through these forums there are a lot of new companies to me with interesting equipment. However, i still have some Orion HCCA 12d's that i have been holding onto. One of the speakers though has a bad coil. My question is, if i got the Orions reconed, will their output compare to these newer subwoofers, like the Obsidians or Sundowns? I am currently waiting on a quote from fixmyspeaker but am questioning if it is even worth getting these older speakers fixed. Also, if i do end up getting new subs, what pair would match up well with my Orion XTR Pro 2400? Thanks in advance.
