Good luck.

Never got REW EQs to transfer to my MiniDSP 2x4 but I'm mainly using it as an outboard crossover to dual subs and used REW the manually EQ the subs using the parametric equalizer with decent results so happy for now.

Your face looks familiar, (I've been in Santa Rosa since '84), I think I've seen you in the Sherwood Forest neighborhood where my daughter lives in a rental we bought in 2013.

Hey guys I have the filters and MDATS now and have a folder in Dropbox but when I share it it gives me options for email, name , or group so if you let me know how to a\share it on here I will, otherwise send me a pm with your email and I’ll send the link

After installing Dropbox on your PC, drag the MDAT file to the Dropbox folder:





After the file is successfully uploaded to Dropbox, you will see a small green checkmark in the lower left hand corner of the file's icon, as shown above. Right-click the file icon and select "Copy Dropbox Link" from the drop-down, as shown below.




On AVS, open a reply post, click on the Link icon in the message toolbar, and paste in the link. As a courtesy, change the "dl=0" to "dl=1" at the end of the link (makes the download easier for the reader).

Yes. Click "Save All Measurements".

The file I downloaded is called "Current.MDAT" and contains all your speakers including the two subs. Is this the correct file?

Since you did not provide a measurement of the combined sub response, I used the REW Trace Arithmetic function to get the combined response. Here it is:




Using the following REW EQ Tool settings:





I was able to get this predicted response curve:





The predicted response is clearly improved between 70Hz and 150Hz, except for that dip at 120Hz, which could be SBIR. Below 70Hz, the dips are too deep to correct, given the 10dB correction limit I imposed. My suggestion would be to try some different sub placements, because the response below 70Hz is not great.


Here is the filter coefficient file for loading into the 2x4HD:

So you apply the same file for both subs? I thought the eq was applied separately to each output? So I would load that file into the eq input? And then just do time delays in the output? Speaker boundary response, is there a way to fix that or is that not a problem?

Yes, you should be able to apply that PEQ filter on the input channel so that it applies to the combined sub response. Did you look at the settings I provided? I did not get any warning when I generated the predicted response curve.

You should be able to do this yourself in the future, especially if you experiment with different sub locations as per my recommendation. Each new location requires a new run with the EQ Tool. Does your disability make it difficult to move the subs around?

Yes it does I will not be able to do it till this weekend. I have the subs located at the front of the room in 1/4 from the corners as sdurani suggested I might be able to move centered on the front a back wall but I’m limited as my room is small

To answer your question about the settings, I ran a combined sub sweep and used your settings no problem. But how do you export the filter I used the export filter to txt button but it produced the file included in my folder
Answer: use the coefficient button

Does this mean you have loaded the PEW text file that I provided? Did the bass improve?


TBH, the recommendation by Sanjay to place the subs at the 1/4 and 3/4 spots is a good one. I follow that myself, with good results. I also have two more subs at the midpoint of the back wall, which probably smooths the response quite a bit. I would listen to the current sub setup with the new PEQ filters before moving anything around. It may be good enough.

I’ve included the MDAT for the combined subs in my Dropbox. I produced a filter for it. It looks close to yours but if you want to check it it’s there.

The important question is whether you hear an improvement in the sound?

Well I’m going to upload it this weekend and then do a full ARC calibration on the Anthem. About the distance delays the subs are both at the front but one is down firing the other is front firing so they are about a foot different. How would I enter that in the output?
About the SBIR can that be fixed by moving them away from the wall?

The dip in the sub response is 120Hz. Plug in the distance the subs are away from the wall into the formula, and it will tell you whether the dip is associated with SBIR. Also, if the dip is above the crossover point, it may not make any difference. Measure Center+subs to see if the dip is still there. If no, then no need to worry about it.

As for one sub down-firing, and one front-firing, why did you do this? Was there a measurable improvement in the sub response? As far as calculating the delays, the 2x4 guide linked in my sig talks about how to align the subs. Input your best guess for the sub delays, then measure each sub by itself. Observe the impulse overlay, which will show whether the subs are aligned with each other. If not, adjust the distance on the closest sub, re-measure, and look at the impulse overly again. Repeat until properly aligned. Fun, isn’t it?

Time to call it a day here in Central Texas...

Well I didn’t buy them at the same time the fist one is and old Outlaw LMF1-EX the new one is a VTF-15H MK2. I’m going to buy a second VTF-15 MK2 and put the outlaw at the back of the room. Austin could you look at my eq of the combined subs? I totally removed the dip at 20-30hz

I’m trying to set the correct settings for taking proper REW measurements. Here is my screen
And here is your guide

I selected acoustic timing reference but it only lets select Lt or rt as timing reference. Is that a problem?

Keep in mind that you are using a Mac, and all the examples in the guide are from a properly-configured Windows PC running ASIO. If the Mac is properly configured, you should have a choice of eight HDMI outputs, any one of which can be configured as the Timing Reference channel. Are you still having issues getting your Mac running properly? If yes, then how were you able to provide the measurements file you shared yesterday? TBH, I am confused.

I was running an order v5.19 beta 8 but had “no acoustic timing reference” selected. I figured out what the problem was, when I select acoustic timing reference in the new beta or old I get this result.

These were my settings

I don't mean any disrespect, but you are all over the place. Your first screenshot shows "HDMI" in the output box. Your second screenshot shows "Speaker" in the output box. At this point I have not a clue what you are doing, and cannot provide any help.

And posting both in this thread and the REW thread is not helping.

MiniDSP 2X4 HD help!

Austin, I started the other thread because some in this thread seemed to say I should take the rew questions somewhere else. My apologies for jumping back and forth I was trying to figure out why my REW wasn’t measuring correctly so I was changing setting and testing. That pic is from the testing.

I know now since I’ve tested it in both versions that the acoustic timing reference is the problem. Here are two sweeps the only difference is the acoustic reference settings

Ok I don’t understand where too set it then. I selected the SL as the acoustic reference on the measurement tab but obviously it’s using the LFE channel. Is there another tab to specify the acoustic reference channel?

While you have downloaded the latest REW beta which is good, it appears you have a lot of REW questions and not fully know how to take measurements. Best to read the REW guide in Jerry's signature and relearn and start over before asking questions. First you had questions about EQ portion, then mac user portion, and now having questions about timing reference. While this thread is about minidsp or so we thought which isn't, I think you should read the REW guide and learn it before attempting to learn minidsp/ rew eq portion.


Once you get REW setup and read the guide and learn it, post questions in the REW thread (after you read it). Once you understand it all, then want to learn EQ filters and minidsp then that should be last IMO unless you just have multiple subs and want to connect all subs to minidsp and run it all bypass for the moment without EQ filters or anything.

And to answer your question about acoustic timing reference....select one speaker (could be left or right speaker) and keep it the same for ALL measurements.
