I put a pair of Orion's in here and the sound great. I do wish there was a little more air space but Im more that pleased.Oct 2019 Update:  I love this box I even bought a second one to use "with" the last one. Very good craftsmanship worth every dollar.... Twice!

    Definitely worth the money
  

*by J***N on Reviewed in the United States on January 30, 2019*

Order thos box to get better lows. It worked. This enclosure is a little heavy but it has plenty of volume and air space for my Rockville k9 subwoofers. I'm running a planet audio 5000.1 Anarchy series amp  with this sub and box combo on a android head unit and it is installed in my 2009 Honda pilot.
