Hi first time poster...

I am looking to add a sub to my speaker and amp setup I have currently, and hoping for advice on which to look into more. Im looking for a little extra boom at the lower end for my movies while not sacrificing quality while listening to my vinyls. My room is about 13x20.

Current setup is TT>Rega Brio>Dynaudio Emit

Trying to decide between:

REL T5
SVS SB-2000
Velodyne impact 12"
BK xxls400

Are there others I should look at? Which are the favorites of the above? Anything else I'm missing? I need something that will be ok with my Rega (power, speaker line, etc)

Thanks
