UPDATE: Please note that this is a basic guide to get started and many mistakes were made that were brought to my attention after the video was uploaded. Apparently you can export the EQ as a txt file and upload directly to Helix. Also, Peter from PSSound responded on Facebook and stated this:
"You measure in 1/48 highest resolution, so you can see EVERYTHING! All the narrow dips and peaks too and THEN you can apply 1/12 or 1/6 smoothing. Also, mic technique is not the best as mentioned above, so you base your filters on a slightly false measurement. Then the target curve is selected quite wrong as if you have to use more than +4-6dB (and you did way more than that in the lower midrange), you’ll overdrive the DSP outputs to clip. Rather select lower target level and in given cases you may need to select different Xovers too, readjust gains. Like in your video if your mid can not deliver the lower midrange, then increase the HPF on it."
This video is outdated and will be replaced with a newer refined version in the future.

Be careful “boosting” those dips. I’m new to REW but from what I hear, dips can be (most likely are) cancellations caused by your room/car. it’s only gonna cancel harder. And you’ll just be wasting power. And/or ruining your speakers. Better to cut peaks. Speakers not in a system don’t usually have a giant dip in their natural response.

Great Tutorial. Learned a lot from this. Thanks.

@Leysner77 2 года назад

is this also posible when you have a passive filter setup ?

@adleneamir4068 Год назад

Hello can you make a video about measuring technique, how to place and where placing the mic

@joaoalmeida9411 2 года назад

Can you try to move the mic slightly and remeasure again? You might be incorrectly equing some phase issues.

Great video!

Great video! One question about EQ of drivers together (L&R tweet, L&R mid, etc): when making adjustments to EQ does it make a difference which side (L or R) you boost/cut frequencies as long as a desired result is achieved? And do YOU personally EQ them together in pairs or is individually good enough? Thanks!

Dónde puedo conseguir ese archivo que usas para las curvas objetivos?

Different ways of doing things, I would have raised the gain in the mid amp slightly so I would cut in the EQ and not boost as much. Sometimes boosting clips the ch on the DSP.

@andrekrausz2407

Thanks for the video. But at

@anggarrahudhi8403

please tell me the set up of the tools you use. microphone and so on?

@Sku11Leader

Where can I find that background?

@surrealartphotomanipolatio5271

When making measurements to set delays between the speaker and the listening point, should the measurements be taken from the grille to the listening point? or would it be more correct to remove the grilles and take measurements from the listening point to the base of the speaker cone without the grille?

I saw the jl dsp with a rta function in jl dsp software ..

@clydesharman2053 2 года назад

Thank you for the video I think the trickiest part is being sure REW settings are correct which without this video I would have never figured that out.

@onesikm3

Did you learn by now that you could export your eq tune file directly from rew if you just clicked save as .text file in the eq section and upload the file directly to your helix dsp ? That I wish I had 😢

@cencao5045 Год назад

I remember that your homepage has a lot of videos, why all of a sudden these are the only ones left

@beherit98 2 года назад

hi, really keen to watch your video and learn. but the lack of volume is really not helping.

@chrisselke449 2 года назад

Don’t boost if at all possible. Lower the mids hp filter then yoi don’t need to boost all of that.

@derekhallett6946

Silly Question here, are you sitting in your car doing this? I'd rather not sit in my car to do this but I can't figure out another way. I'll be attempting to replicate this entire video using REW (keeping your post-video edits in mind) going into a set of VXi amps.
