Are you referring to the EMP 1010 sub?
I like my RBH (big bro) SX-1010N subs a lot because of this vertical real estate. It's almost like a tower speaker. Why, if you stack a bookshelf above this vertical tower-like sub, it would look just like a big tower!
I just ordered 3 more RBH SX-1010N; I already have two. So now I can place my 5 KEF 201/2 bookshelf atop the 5 RBH SX-1010N subs.
I know I'm supposed to be SELLING, not buying more, but I just could not help myself.
