Sub Integration with RME+ROON

[Mehdiem]

Hello Folks!

I would like to see how can I improve my sub integration. My current set up is as follows:

Preamp RME ADI-2
- Primary input: from USB - playing from ROON
- Secondary input: Optical from TV
- Output: XLR to Amp (NAD C298)

Amp NAD C298
- Output: Speakers KEF LS50Meta
- Sub Unbalanced Output: to SVS 3000 Micro

SVS 3000 Micro Sub
- For music listening: Using SVS integrated EQ for Music (using SVS app) Freq 63hz, 2.0 dB, 2.4 Q and Freq 63hz, 2.0 dB, 2.0 Q
- Low pass 70hz
- For movies: I turn off the SVS EQ and increase the volume by 4dB
- I switch between music and movie mode using SVS iOS app.

What I'm hoping to achieve:

1) Better SUB integration that could improve the overall quality

2) Currently when I play different music, I feel the need to tailor sub volume (using SVS app) by about 5-10dB depending on music and mastering to have seamless integration and optimal level of bass. I am hoping I could set predefined ROON EQ for each of those scenarios to avoid using SVS app each time

To that end, please help me understand:

1) If should I connect the sub directly to RME unbalanced output (instead of my amp) and whether I get a better integration and sound quality?

2) Should I change or tweak any setting in RME when I connect the sub. Please provide guidance on what menu should I change, as I don’t know.

3) All my EQs (for my speakers) are set in ROON. Should turn off SVS EQs, and instead I set any EQ for the purpose of SUB in ROON?

For an ideal sub integration you should have all speakers on a separate channel, check out this post as a start:

Fail with Maop 11.2 matched pair

...so you are boosting that null by about 20db at 65hz? If you want smooth frequency response why are you using full range drivers? What is the rest of your signal chain? Have you verified that chain is flat to 20khz?
