Seems tough to ensure only subwoofer is playing bass frequencies (& not the main speakers)

Given that the bass from main speakers will be qualitatively different than the bass from a subwoofer...  I do not want  them both playing the bass frequencies. Seeking help in this quest of mine to ensure only the sub plays the bass. 

**My Setup:**
- Source: Oppo UDP 205
- DAC : Black Ice Audio  Glass FX  (fyi: it has volume control)
- Integrated amp: Primaluna Dialogue Premium HP.  (no pre-outs, but has high level mono out and also HT bypass mode)
- Subwoofer: Velodyne DD+ 10 inch.  

Without the DAC in the picture, its pretty easy. The Oppo has bass management & dedicated sub output. This allows using the oppo for master volume control.

How can I use an external DAC (instead of whats built into the oppo) for both the  and continue to send bass frequencies to the sub but not the main speakers ? 

one thought i have is.. it will need introducing an external digital cross over as follows :

Oppo -> DAC -> Cross over -> Subwoofer & Integrated amp

In which case i suppose I would have to use the volume control on the DAC ?

I also run my speakers full range (down to 20hz) and reinforce the bottom end with an audio Kenesis swarm inspired subwoofer setup (two additional subs). The subs play from 16-80ish hz and integrate really well. If you can echolocate them, something is setup incorrectly (i.e., either volume or the sub's low pass filter cutoff).  

As you can see, there are lots of ways to play the game even with your current setup. Try them all and choose the winner. Do note that people tend to over cook their sub volume levels because they like to hear thump coming directly out of the unit. This ruins integration with the main speakers.
