Wow. Best REW/mDSP tut so far Imo its the best becuase you went through the whole process in detail and patiently Others , all though pros . They have no patience for it. You can tell , they just skip so much of it . They cant be bothered going into detail Thankyou very much for showing the WHOLE process from start to finish This vid will help so many of us starting out . 🙂👍

brother this has got to be the best tutorial for REW I've seen thus far. Been waiting for this one. Thanks so much

The second time you ran the eq basically undid everything you did the first time because you ended up eqing with the mains, whereas before you were only eqing the subs. I appreciate the fact that you uploaded a video showing the process, because there are a lack of videos detailing this process for sure. Your rew results looked great at the end so congrats on your hard work.

Good stuff Corey, I use 4 subs and found that listening while adjusting the delays in each channel by ear with music was the only way I could dial in the lowest frequency rumble, experimentation with inverting the phase on individual channels is a must, so many variables to allow you to get the sub frequencies right, using the REW to get the smoothest response curve is great, but the final tweaking for me had to be done by ear. The minidsp 2x4hd is an incredible product, nothing even comes close for multiple sub users.

Thanks for the tutorial! I'm still nervous about doing this but your video sure helped me.

This was immensely helpful. Thank you.

Great stuff, it helped me a lot with the EQ-ing, even though I only did it for stereo. However, it worked for me to a great extend. Thanks !

The end result was pretty amazing.

Great video will help me a lot in my learning of same setup as yours Thanks buddy. I have subscribed. Told my friends too we all are newbies in Minidsp and rew

Fantastic video Corey. Very handy mate. Subscribed

The alignment tool built into REW within the controls tab would've saved you a ton of time doing this. Input sub 1 and sub 2 and adjust the sliders and it will give you a predicted frequency response based on the delays. Really powerful tool! I used to do what you're doing and it was VERY labour intensive! Try it out next time you're doing a calibration. Yes, I appreciate this video is over 2 years old. 😂

The "LR" and "BW" designations in the crossover settings stands for "Linkwitz-Riley" and "Butterworth". Basically an "LR" filter is comprised of multiple Butterworth filters. Linkwitz-Riley crossovers are flat, whereas Butterworth filters have a 3dB bump at the crossover point.

Thanks, I'm working on it too, but can better, but you have a good clear explanation, will there be another video for setting multiple seats? i hope so, 😉 then i understand everything when you make that video 😁

Well done 👍. I don’t know what I’m doing wrong but I only can get the sound out of my left and right front speakers no sound out of the subs

Excellent tutorial Bro

I agree but the miniDSP doesn’t have XLR inputs so if you wanna integrate the subs using that device it’s the only way. Or upgrade receiver with better room correction like separates.maybe MiniDSP has a different product with XLR inputs idk

Nice Work. Should have worked REW on your mains as well, at least to tune for delays and flatten the frequency. Then X-over with your subs and see what you got. Dont need to tune beyond 8 or 9khz. Some say dont need to tune beyond 1khz. The X-over filters you were working with were Butterworth= BW and Linkwitz Riley= LR take your pick.

Is it just me or is there so little on YT in the way of measuring a pair of nearfield monitors less the sub(s) Thank you for sharing by the way. Much appreciated

Very good video! What volume level did you set the AVR during the measurements?

Hello, Corey! I have some pair of speakers and they aren’t straight, they are as straight as a roundabout! So I wonder if I could connect these to a stereo speaker. I’m thinking to put in a stereo rca cable and then go through the miniDSP and a rca cable as output that connects to the amp, could I do that? I’m sorry if I where unclear, English isn’t my first language, what I wondered was if I could for example connect left Chanel to input 1 and then configure output 1 as output for just that Chanel so I can use a equlizer and then for example I connect the right Chanel into input 2 and then use output 2 for that Chanel and use equaliser for that speaker. (I don’t want them to interfere) Great video btw!

Thanks for the review though

What about phase response using the MiniDSP? Seems to me thát is important as well for having a balanced output (listening experience)

You should have used the PEQ to adjust those nulls,it is really powerful.

Corey, I noticed you ran you sweeps at -21dbfs. I’ve seen the defaults are usually -12. I’m struggling with this step (level matching). At what volume was your receiver when you ran at -21? I know it’s always room specific

Great Video. I am new to REW but your video is great help. Did you have to configure any settings in REW before started lining the subs?

@coreyskinner - when you said to rerun audyssey again, did you mean to exclude or include sub channel from audyssey calibration? Please clarify

Awesome. Thanks.

Thanks for the helpful video. Is the mic also plugged into the laptop?

Awsome 🤘🤘🤘 I will try highpass only cause my neighbour is mad 🤪 Subs rated to 11hz, measured to 8 hz 😁😁 Btw, neighbour is a different house, 80 meters away 🤪

After running REW. My subs were to loud for Audyssey to run. I lowered the gain on the minidsp to get it continue. When it was all said and done the setting for the sub was -12. I ran the pink noise on the Denon using the spl meter and umik-1 to put everything at 75db including the subs. Was this correct?

Did you gain match your subs before starting?. If not id suggest watching the REW from Home Theater Gurus.

After you were done tuning the subs, you said you were hooking up your mains. What did you mean.? I've never used rew, but am thinking on spending the 450 cnd for the minidsp and umik. The minidsp is only for tuning your subs, right? Since you only gave the two inputs from the sub outs on the receiver? I'm sorry, I'm a total newb with this.

Hello Team, I need some help darling in my subwoofers, My question is should I add a house curve in the mini DSP and then run anthems ARC room correction or just use the mini DSP to flatten the response and then add the house curve in anthems ARC room correction? I’ve tried letting the anthem do everything but I think incorporating a miniDSP will achieve better results. I can’t move the subwoofers around my room to improve their in room response as I’m very limited with space.

Bro those delay settings are huge. I don’t know what your setup looks like but if this is the way you’re doing it, I’d try like .5 .6 .7 etc.. 9ms is like 10ft in distance. Also something small like a .2ms could be the difference between peak output and a huge dip.

my receiver doesn't have front hdmi, can I just use the hdmi 1 from the back?

Just to be clear, you are using the miniDSP 2x4HD, correct?

After you created your house curve did Audyssey not trash it?

Awesome vid, thanks heaps, one thing i cant get past is in the setup, in minidsp my reading of is -99 dBFs where as yours is -75, am i missing something?

What if my subwoofers are connected with XLR? How do you connect to mini dsp in that case??

If you are running deal subs would you not connect both from avr with 2 independent sub outs ?

Did you use another eq like Dirac or audessey for the mains? I’m am Little bit confused if I should use XT32 for the mains and a mini dsp for the sub.

When doing sweeps is audessey/deq ON?

I need help I just got a new mini dsp 8×12 I don't have the software I need help

Hi, Thank you for sharing, I learned a lot. So my subs are Rel 1508, and they are stacked on top of each other. So when I take individual measurements, they are almost exactly the same. And then both at same time, are just louder all around. So I guess "delay" is only for when they are on different locations? Thank you!

When u ran a sweep on ur mains. What changes did u made in your amp in settings and in rew ?

Did you gain match your subs before you did this? I heard gain matching should be done with REW first. And since you use front corners like me, you should pick whatever corner that gives you the best bass and use it with both subs to get them properly gain matched (don't SPLE the subs where they are already. For me that is the right corner)

Ok I have the minidsp 2x4 hd I have the power hooked to my power conditioner I have the USB into my laptop also have the umik1 plugged into my laptop I have the minidsp input 1 running to my emotiva xmc2 with my 4 subs plugged into the output side of the minidsp I have a fiber optic hdmi cable from my processor hooked to my laptop I have my rew all setup correctly my minidsp 2x4 hd plug-in downloaded connected with everything hooked up correctly I have double and triple checked but when I check ny levels and also when I try to measure I get no sound

Are the test tones on rew or did you import them? Is there pink noise on it also?

Did you connect the mains to the minidsp and set high pass filter?

i cant get mine to do a sweep anymore... not sure what im doing wrong

Does it matter what you have the crossover on your receiver set to? What was yours set to when doing this video?

Didn't you use outputs 1 and 2? You are doing output 3 on the second sub

I had mine on 80hz and all set to small.

Hello, do you know if it is possible to make phase correction as well with miniDSP ?

Confusing! Confusing! The video was pretty good when it comes to connecting the wires did a great job with that but then once you got inside of the software start running test and talking about how to connect the mic and all of that confusing I would love to do my subs but this is too much for me to do I don’t understand any of it

YAM ....aha! it literally sounds like you tried to surprise a vegetable. Good video though!

WhAt sub is further away from you?

MILLISECONDS 😅

go ducks

This company is a joke. Save your money. You will regret ever dealing with this joke of a company. You will wait 36hours for a response from their ‘devteam’, on hong kong time, and only via email, just to be told to ‘read the manual, it helps’ Seriously, dont give them your money. You will be living in anger and regret like me and many others.

PEQ boost and reductions for each sub 1st ,to get best response per sub then delays on one sub to get best summation of all subs.
