Added A Second Subwoofer To System

I haven't created a Virtual System yet so I will give a quick overview of my room and system.

I'm currently using a Classe CP-50 Preamp into Black Ice Audio Fusion 3502P power amp using the balanced in/out.

Speakers are Sonus Faber Lumina III's.

Subs are SVS SB2000 Pro and SVS SB1000 (not pro version)

Room is 13'L x12'W x 8' H

Subs went from both front corners of room to half way along both side walls.  

Listening position is approx. 7.5' from main speakers and 3' from rear wall.

I like the way the bass sounds with the subs in this position and although they appear close to my listening position, I can't hear or am aware of their locations.  

I set the phase for loudest output at these new locations.

My problem (?) is I feel that the overall volume of my system has dropped a bit.  I feel the need to turn the volume up a little louder than I did before the change.  

I'm actually concerned that I lost a little hearing overnight.  I am 63.  In all seriousness,  I doubt that I did although I know that hearing loss is inevitable.

Anyone experience anything similar?

My 3 subs are integrated in a way that boosts certain frequencies and attenuates others which were "boomy" because of room acoustics.

When the subs were adjusted to cancel out (attenuate) certain frequency peaks, the overall volume appeared to go down. But the other frequencies were allowed to come forward, no longer obscured by peaks from 20-300 hz. 

There's no substitute for measuring these things, in my opinion. The free REW Wizard program plus a $100 Umik is one indispensable way to do that.
