1 Subwoffer for a small room

[ezra_s]

So, I'm thinking on getting a sub for my room as my self-given birthday present.

My room is small, and my budget is limited so I want to buy a good subwoofer which can go as low as 20hz or so if possible, it probably will be the only one I may be able to buy in a long while, so I better do it right.

I have two scenarios, if possible I'd like to be able to use both cases without having to be playing around with cables:

rme adi-2 dac (as dac only) -> moon 220i integrated amp with rca- pre-out output
rme-adi 2-dac (as dac pre-amp) ->behringer a800

So, ideally if sub has "rca in" and speaker in - speaker out I think it would be great (I'm not too knowledgeable about subs so If I am saying something incorrectly please do correct me)

Room is 11m2, about:
Width: 5m (left-right)
Length: 4m (front-rear)
Heigh: 2.40m

Budget 600€ max

Europe shopping only.

Any impossible to miss suggestions?

Edit: It can be two subs if there is an awesome offer, but budget remains the same
