Can two subwoofers reduce a bass problem?

@erik_squires 
48 and 127 are peaks and a actually have a dip at 70.
EQ; from where do I get an analog (I'm listening much on LP:s too) mastering EQ cheap? I can't ruin the sound with some cheap budget EQ.


A strange thing happend when I replaced my old Supra Annorum speaker cable to Kimber 8TC. Besides giving a more open, wider sounstage with a tighter bass the problem with the bass peaks also was reduced. Now it's more like the peaks has become more narrow.

I'm looking at REL T5i and REL T Zero and wonder if I get a better result with two T Zero than one T5i. With two T Zero I might counteract my bass problems a bit, but on the other hand I will not get a real low bass.
With a T5i I will get low bass but maybe it will increase the bass problem again.

My smallish room is not just a listening room so I can't just put four subwoofers anywhere and build bass traps or a Helmholtz.

Now I remember why I bought a new headphone amp and new headphones:)

A very interesting way to control the bass frequenzies. But sadly it's no option for me since I have an old integrated tube amp and the only outputs are those to the speakers. 
I'm looking at the REL T5i (and T Zero) because I think their high level input is the best way for me to connect the sub to an amp.
