Towers with built in subs vs separate subs

Treatments are in the works.  Waiting on wife approval. 

My room is L shaped. Main part which consists of living room and kitchen is 20 deep and 23 wide. To the rear of that, all open, there is a 15x12 dinning area.  Lots of hard surfaces. System backs to stairs going to 2nd floor. I put a second floor on a 1200sq' ranch and blew most of the walls out of the lower level.  I just posted some pics if anyone cares to look

The 120H speakers do have a port on them to use anthems room correction system which is supposed to be preatty good.  I understand the benefits of separate subs but given very limited options as to placement and the built in room correction of the 120s, the built ins are probably the way to go. I think Anthem/founders is having a sale right now too and I just bought the mrx740 avr which comes with the room correction stuff. Thanks all for the help.  Now to pitch it to the wife....wish me luck

Thanks!  She kinda went down the rabbit hole with me. She likes the tech end.  She actually bought the founder 90c center to contribute to the cause. 

Thanks again all!

@ditusa ,  multiples simply aren't an option unless i stack them. I have 2 options as to placement...next to the R or next to the L.  My first choice would be to get a bad ass rel s series, but.....if placement is that important ,Im limited.  So why spend the $$

Thats quite an endorsement saying the paradigm are better than the focal. 

Mr Soix,   i guess my question would be to you and others that think separate subs are better,  and i agree, they probably are, but can the room correction in an imperfect room with limited options as to placement get close to the results of doing a sub crawl with multiple placement options?
