Questions/Request for additional information on Equipment:
- Subs: 16 cf ported box tuned to 16 hz, loaded with UM18 x 4
- Power: 2 Behringer NX6000
- Power info: I have the knobs turned all the way up. When I'm pushing them, the clipping red light will come on. Only for a split second though.
- Other Equipment in chain: MiniDSP HD
- Are the NX6000 on a dedicated circuit? Yes/No
- If Yes - what amperage? 15 amp, 20 amp, etc
- If No - what other items are also connected to this circuit
- Post screenshots of your MiniDSP configuration for each tab
Questions/Request for additional information on Room Configuration
- Size: 12' across, 20 ft deep, and 8 ft high. So 1,920 sq ft. I sit 11' from MLP.
- Misc info: The bass quality is okay. I think I was hoping for just a little more there too. I hear a little overhang on the bass. I have bass traps and heavily treated theater (about 30%). Whole front wall (membrane), 20% of side and back wall.
- Graph from post 15:
- Graph from original post:
- Please post pictures of your room so we can see where each sub is located in relation to the other subs, your seating, and your room treatments
- The graphs, what order are they in? Is the first graph the initial configuration and the second is after running your AVR's room correction? Is it after doing work in REW to export filters into the MiniDSP, etc
I'll make this the long post, so we can all go off of this one.
I was working on the theater tonight.
Here is what my room looks like. I don't know why the sub pictures are showing sideways in the individual pictures.
Tonight I rotated the front two subs so both point towards the side walls on the outside of the center channel. Just to compare, here is a picture of where they were before. The second to last picture in the attachments is the current measurement with the subs facing out towards the L&R. The last picture is the overlay, the blue is subs faced out, the orange is subs faced in. Looks like moving them to facing out towards L&R gave me more mid-bass, more SPL, more linear, seems like a good move right? Again, no filters on the minidsp.
Today I was pounding the subs pretty hard. Multiple times, I took them to distortion, and then turned them down.
Does it sound good? Yes. Does it sound great and impressive? Honestly, it's okay. I want great! The problem is is that I may not have the room for many more if any. Which makes me wonder if I need to try and put another UM-18 on the top part of the boxes. But then would that mess up the ports I have in there.
Ugh... I want it to sound great. That's the bottom line, so what should I do?
The amps are on two different circuits. I had them on one, and it tripped the breaker a few times. Since putting them on two different ones, they have not. I don't know if it's 15 or 20 amps. On the one circuit I just have one of the 6000's, and then on the other one, I have my receiver and the other 6000.
Not to over complicate things, but I have been eyeing up DIYSG new Titan 818's, 615, or any other model that you guys would suggest. That may help with mid-bass (may not be enough I don't know.)
You guys are awesome thank you!
