Subwoofer hunt

Thanks for the reply bob. Small as in how small you think I should go in for say about 200 sq ft room?

@willland : Thanks Bill. 

@yogiboy: checked out SVS. Most of their 12 inch subs but seems Rythmic beats them for music as per the reviews. Anyone compared SVS vs Rythmic?

@alpha3 : Most of the RELs have front and down firing dual driver subs which might make it more boomy. I am looking for a something thats more tight and resolute than boomy sort of. however let me spend sometime and go over them as well :) thanks for the help 

@willland : in the tristate area what do you have :)

@bob_reynolds : Thanks Bob! I am looking into the HSU sealed ones as of now. However, I had read on the JL's site for reviews of one of their models that the amp had failed on the buyer within 6 months of purchase. I was curious to know if HSU subs are reliable.

@oleschool: thanks oleschool! :) noted....im trying to decide between E110 by JL and F12SE by Rythmik

@hifiman5 thanks for the detailed post hifiman5. one quick question, wouldnt the current on the speakers drop if you connect subs to them in parallel? because current would decrease for parallely connected components right?

@jldouglas : thanks jldouglas. You think I should give E110's another chance and listen to them with my setup? I was leaning towards the Rythmik F12SE.

Thanks guys for all your inputs. However I still have one more question :) promise this would be the last. 

So if I plan to just connect "ONE" sub for now. and if I still want to go with the high level inputs and not the pre-out from the sub how do I connect since there are two channels out there left and the right. Which one would I connect to?
