Jeff the more I read the more I think that an MBM would be our next step for bass bliss.
But I continue to wonder about the frequency response below the 18hz tuning point of our subs. It is true that with room gain we can possibly reach the depths of 15hz if we are lucky. But that still leaves us with sub 15hz bass that we cannot hear....well "feel". That to me is a level of bass that I want and need.
That being said, I wonder if adding an MBM and then a 2nd PB-12NSD is going to be the right move for us. Regardless of how many PB-12NSD's we add we cannot LOWER the frequency response, we can only gain more headroom.
Obviously the MBM is a good idea for ANY set up because of the mid-high bass that it dominates. Then I wonder if our next SVS step should be something OTHER than another PB-12NSD so we can attain that sub 15hz bass.
---Should we go a single driver ultra and set it to 10hz mode and set it on top or underneath our PB-12NSD?
---Should we get a 16-46PCI PLUS and set it to 12hz mode and set it right next to our PB-12NSD?
---Should we get a PC Ultra and set it to 12hz mode and set it right next to our PB-12NSD?
---Is there another SVS option that would give us what we are looking for that we are not currently thinking about.
Would these combinations totally cover frequency range that all movies cover?
Most notably I'm thinking about Blackhawk Down and how IRENE has bass from 5hz and up. I don't just want 90% of the bass covered in my system, if I'm spending this much cash, I want it all covered.
