Tough decision on subs

[ukrosie31]

I posted this on another thread and thought that I could get more imput by from all of the experts out there with a new thread. The issue:

With the VTF MK3's improvements, I have a tough decision to make, please help steer me in the right direction. I already have a VTF-3 MK2 for my audio only system in my study and love it. I'm now in the process of building a home theater in the basement of my new home; room dimension 21'Lx19'W with a 7'-8" front half ceiling height and 7' back half of the room ceiling height. I'm also building it with acoustic walls and staggered wood beams, etc...

With price always a consideration (keep the intro prices going for a while longer please), what combination or single subwoofer do I go with (I,m keeping the VTF-3 MK2 sub upstairs for my audio only room)?:
1. a pair of VTF-3 MK3s
2. a single VTF-3 MK3 turbo or HO/turbo
3. a pair of VTF-2 MK2s
4. or just a single VTF-3 MK3
or 5. something else...

Thanks

For strictly HT use in that size room I'd go with the VTF3-HO w/ turbo plus a MBM-12. Or if that's too much of a stretch just go with the HO for now.

I second that!

ukr, I would probably lean towards getting a single VTF-3 Mk3/HO with turbocharger placed farfield handling 15-50Hz, and an MBM-12 placed nearfield next to the primary listening position handling 50-80Hz.

Thanks for all the recommendations.

I did not consider the MBM option, that's something new to me, but makes a lot of sense. Too bad for me, I just moved from SoCal to the East Coast, I should taken the opportunity to visit the Hsu listening room (as I did before I purchase my first sub) to hear this setup. I will give Peter's rec more thought.

BTW, when the stated frequencies for far- and near-subs are set, is that done just via the sub itself. Or, are you passing a signal through a high-pass filter?

What I have read so far is that you would split the sub pre-out signal to both the MBM and VTF-3. I believe that the MBM naturally rolls off at 50Hz. So, you want to engage the crossover for the VTF to IN and set the low pass filter to 50Hz so that it would take care of the low bass. Correct me if I'm wrong.
