What sub under a grand?

I have a REL and I like it a lot. Hsu subs would probably be my second choice. Yea, they're made in Red China and that sucks, that's the reason I went with the REL. The Hsu VTF series has a lot of control built into them. Bass ports, you can plug one or both with the supplied plugs. They also, have a Q control which can help get the tight sound you may want. Just a thought.

I just lost a detailed post for the OP to use as he see's fit, but I'm not going to sit here to 'hunt & peck' to retype it. Short version, is I recommend you look into HSU, SVS or Rythmik. Those companies will have what you need to play the mega bass in the movies like you desire. I believe you can easily do it for under a $1000. I have found that the HSU VTF series will give you the most flexibility and the best chance of reproducing the bass as you like it. The biggest reason I didn't go with a Hsu sub, is they are built in Red China and when I can find an alternative to China I take it.
I would use the REL you have now strictly for music as you said it works ok, on music.
Good luck,
