Hello Everyone,
So I just got into more in-depth tuning of my home theater system. I am forced into a lot of compromises since I live in a condo. My entertainment center has to be in the front right corner of a somewhat large and open living room. Moreover, due to furniture (and spousal approval concerns), the only place I’m able to put my dual subs are behind my couch. One is closer to the wall and near a cement pillar which might provide some bass re-enforcement, but the other is behind the couch, more or less in the middle of the room, which I know is a terrible place. Also, one of the main “walls” is ceiling-to-floor windows, though I at least have cloth blinds to somewhat help. I provided pictures of the room for a bit of context, though it doesn’t exactly show how much distance there is after the subs to the back of the room (there is a decent amount).
Here is a list of my components so you have an understanding of what I’m working with:
- Onkyo TX-RZ810 receiver (AccuEq room correction)
- Monoprice Monolith x7 amp (powering all 5 main speakers)
- 2 SVS Prime Pinnacle front towers
- 1 SVS Ultra center
- 2 SVS Prime satellites (ceiling mounted and angled down)
- HSU VTF3-Mk2 and VTF3-HO subs
- MiniDSP 2x4 HD (for subs)
- Jensen ISO-Max ground loop isolation transformers for the 5 main speakers to break a ground loop issue created by my PC
Anyways, utilizing Onkyo’s room correction and REW/MiniDSP to flatten then subs’ responses, this is what I have so far (see the attached graph). I should mention that this graph was taken with all room correction on, in Onkyo’s “ALL CHANNEL” mode since I wanted to see what all the speakers were doing together (I typically use L+R+subs stereo mode when tweaking the subs with MiniDSP). The mains and center are crossed at 80hz, and the surround are crossed at 100hz.
I think I can tweak between 20-30hz further to bring that up a bit, and generally raise the level on the subs to have the lowend raised a bit more, but I’m more concerned about the 80-120hz range, as I’m not sure what is causing that. Is there something I might be able to try with more EQ and minor speaker placement tweaks, or are the responses I’m getting just way too far off.
Any help and guidance would be greatly appreciated. For what it’s worth, I’ve spent a ton of time trying to get the low end smoothed out through EQ already, but perhaps I’m just not doing the best job?
