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 would just connect the subwoofer using its high-level speaker inputs connected to the integrated amps speaker terminals.  Adjust the crossover on the sub so it underpins the main speakers as well as adjust the sub volume control properly so as the volume on the integrated is adjusted, everything stays as one cohesive system.  Super easy and this is how I've been connecting subwoofers for decades.  Mains = full range.  Subwoofer = support/ supplement for the lowest registers below the mains.
