How to Tune a DSP System with JL Audio MAX and TüN4!

When we want to truly get the best performance from a car audio system we must be able to fully tune the system with a Digital Signal Processor. With using a DSP we can tune the crossovers, equalization and time alignment of every speaker and subwoofer in our audio system. JL Audio has an incredible program for this that not only interfaces with their DSP integrated devices, but also with their MAX measurement system, and that program is called TüN4! Let's take a look at the entire process for how to tune a DSP!

Another great video Mark! Thank you for always keeping us well informed! Kudos to you!

[@roedblok267]

Great easily understandable video, just wish it was more clear that you require the MAX if you are trying to perform time alignment. Finally figured it out from one of the JL Audio videos.

[@roberthopkins8089]

THANKYOU for this video so much. Best video on the subject because you use it in the field and stay on topic. I learned more from you in 40 mins than hours and hours of JL's content. Your videos are the best above all the KZbin I view. Your organised and professional throughout

[@lassebrustad]

you just explained why I like to watch his videos, it's just too good content to compare to anything else. it's detailed, easy to understand, but still not too long videos, so it's easy to watch all of it, even as a newbie within car audio, like me

[@OldSchoolCarAudio]

Very informative! Enjoyed watching this video immensely 👏👏👏👏

[@donaldthompson3434]

I really appreciate the video. You will have a million views because one has to rewind often because you talk so fast ( I say this with love bro!). I know this video is old however it would be helpful to make one for dummies, people that are very new to this. Also do you have a general guide for Target's let's say for mids, sub and components. Again thanks for this video and all the other where you explain how to get the best out of the equipment we buy.

I love the JL Max! It’s like 5k here in Canada and it has optical toslink but it would have been nice to have coaxial digital inputs and outputs.

[@carlosgraphic]

38:30 Great video. It will be helpful if making sounds before and after. Even though everyone has a different audio performance they will not listen to the real output but will notice differences. Thank you.

I just bought the audiocontrol DM-810 for my system. Mmats 3000.1, NSv3 15 with underhung coil, SI 3 way. Will be adding; Mmats HIFI-6150, HAT U69-s for front door.

[@TheBBGlobalNetwork]

What RTA will you be using to "listen" to your speakers? Windows based?

[@572012myo]

@@TheBBGlobalNetwork I'll be using my Android based phone via Bluetooth from the DM-810 to tune and stream.

[@angelludia6758]

Excellent video ! What section of cables for the dsp we need to connect?

[@RydinginStyle72]

Thank you for the invaluable lesson. Do you need separate tunes for different types of music? Or if you incorrectly should at play all types with equal performance? Thank you

[@InMotion808]

How do you feel this compares to the AudioControl DM series for tuning a system?

[@chriscuthbertson]

Whats the thoughts on tuning to a flat response and then using a global eq to tune the sound to taste.

[@optimizerben]

What's a good way to generate a preferred target curve for the overall system, using the TUN/MAX system or otherwise?

[@raeldor]

Wow, this software is way more advanced than what I have with my Musway. I'm curious... the measurement at 17:18 (for example) seems way perfect. Is it subtracting the noise floor? If so, did I miss that step?

[@klubstompers]

I like to make 2 tunes. One for windows up and one for windows down. The sound is completely different when the sub freq's can escape threw the windows, and the highs aren't bouncing off the glass right next to your ear. Would be cool if you made a video and showed the differences between windows up and windows down when using one tune, and how different the 2 tunes would need to be to hit the same curve.

[@hyoctane23]

I literally thought the same thing. Get on it, Mark!

[@klubstompers]

@@Pens4Life85 Sure mail me your car.

[@EpiceverythingProductions]

Good thought! Wondering also can the initial tune (windows up) be copied so the second tune can be modified easily for windows down?

[@klubstompers]

@@EpiceverythingProductions I just start from scratch, because the acoustics are so different in my vehicle with windows up and down on the low end and a little on the high end. Vehicle is very well insulated, so sound can not escape anywhere, until the windows come down.

[@EpiceverythingProductions]

@@klubstompers cool thanks for the reply! I can do that! Another question, when making different tunes for rock vs rap for example, did you start fresh each time or did you build off the initial tune and modify slightly? Thank you!!

[@timwheeler1503]

I love all your videos Mark, all great info. I'm currently installing a Alpine Halo ILx-F509 in my 08 Impala. I have a Dayton DSP-408 with 4 inputs and 8 outputs. The Alpine has 6 RCA outs, am I better to run the sub outputs from the Alpine to my sub amp directly, or just ignore the sub outputs from the Alpine and use the DSP to feed my sub amp? Thanks

[@amthanhxehoivietnam]

hello, better you use dsp ch7-8 for sub.w, you can control whole your system instead of speaker and sub.w separately. if you have dsp you only need full range signal from Front left and Front right of Alpine Head unit and use mixer function from dsp to output signal.

[@touring189]

Would it be worth retuning with MAX if I was already tuned previously? I'm active with the VXI's and it already sounds great. Just wasn't sure if MAX changes anything.

[@maks8233]

Which Sample Rate and ASIO Buffer Size did you use for JL Audio MAX?

[@joeponder9668]

How do we go about getting your help with designing a box? I bought a skar 3 evl-10-D2’s and their 3 10 box. The box is 0.6 per 10 and the speakers I got are recommended 1.6-2.0. Obviously installed them and they do good against their 4500w amp. However I’d like to build a box to the correct size and most likely run 2 due to space restrictions as I wanna retain some truck space. I plan on using you amp ideas to mount all the electronics to the back of the seat to fold down in a 2014 Corolla.

[@francislack3362]

Excellent video! Super informative, definitely gonna download Tun. 👍

[@MrMr123]

How does this compare to Dirac?

[@okanaganmedia]

I have a TWK 88 and a FIX 86. The issue im having is once I tune the TWK 88 I cannot save it. Actually it says it saved the profile but once i unplug the laptop, it defaults back. Also, the 3 different lights are flashing, RED, GREEN , AMBER. Why wont it save? Someone mentioned a fuse was burnt out. Very frustrating. Please advise

[@lowdimes8775]

Where can i get one?

[@559Lucchese]

How much would a shop charge to tune your dsp?

[@leaanne4965]

If I understand that correctly, can Tun be used place of REW to measure and analyze the sound?

[@amthanhxehoivietnam]

I'm using REW( RTA Dbx-m and sound card Focusrite Gen 3) for tuninh dsp also,but all of thing have to manual don't have enough function like JL ( hard ware and interface of soft ware so friendly)

[@user-hk4cj4fc8q]

So there's no way to get time delay data without MAX, Maybe I'm confused a little. If i'm using TUN as the signal generator in to the head unit AUX wouldn't TUN be aware of the start point?

[@KaiCam808]

If I am going to use a USB mic is there anyway to test speakers and get them in phase without the max?

[@crewdawg16]

Obviously I'm a bit late to respond to this, but you cannot directly observe the phase without the max as shown here. What you can do is look at the "summation" of the speakers using a USB microphone and the RTA function and look for any serious nulls in the response. For instance, if you observe the output of the left midbass and you unmute the right and it doesn't add equally across the entire range - you can see where the frequency of the null is you should be able to apply an all pass filter in that area and see if it helps or not. It just becomes a trial and error process.

[@TheBBGlobalNetwork]

Hey Mark - While the JL TuN software is "free", It appears you must have a JL DSP for the software to work. You mentioned the Measuring aspect is free, but I can't get it to work because TuN is looking for a JL DSP (upper right corner says "MAX not detected"). I have an Audio Control DSP and want to use only the Measuring aspect of TuN. My goal is to run Audio Control DM Smart app on one Windows laptop and a RTA on another Windows laptop for tuning. Can you recommend a good FREE RTA for Windows OS? I do not want to use REW because it cannot show real time data. Thanks and keep up the great video's!

[@CarAudioFabrication]

You can absolutely use TuN with just a USB mic in measure mode. You will need to make DSP adjustments in the separate software for the non-JL DSP. TuN isn't going to be able to "talk" to a non JL DSP.

[@TheBBGlobalNetwork]

@@CarAudioFabrication Understood however TuN will not run unless it detects a JL DSP. Try it yourself. Disconnect the JL DSP from TuN and see if you don't get "MAX not detected" at upper right in the app. It won't work without a JL DSP. You should add that disclaimer to your video Mark.

[@CarAudioFabrication]

Incorrect. I just booted up and launched into measure only mode with nothing attached. Make sure you have the latest version of the program.

[@nicholasames4607]

@@TheBBGlobalNetwork so, “MAX not detected” is simply the message that software gives when in Measure Only Mode if you don’t have a MAX connected. This simply means that stuff which cannot be done with a USB mic, like real time transfer function measurements, won’t be available, however the Auto Match to target (AutoEQ) still works, you can still take RTA measurements with any connected USB mic or Audio Interface, and the full target generation system works unimpeded. When you plug in a JL DSP, like VXi for example, this “MAX Not Detected” message is actually still there, it’s just on the “Measure Settings> General” tab now. The area of the UI that you’re referring to will now show the currently connected JL DSP model number (such as VX800/8i). To be clear, as Mark mentioned in his reply, there isn’t a single measurement function, with or without MAX, that is dependent on having a JL DSP connected. Not one. The only thing that you don’t get if you don’t have a JL DSP connected is, obviously, the ability for you to control your DSP of choice from the same UI as the JL Audio TuN measurement software

[@TheBBGlobalNetwork]

@@nicholasames4607 Thanks Nicholas. I will try again. Yes, I do understand that TuN cannot adjust a DSP unless it is connected. What I'm trying to set up is a two laptop situation; one running Audio Control's DM Smart app connected to a DM 608 DSP, and the second running RTA software with USB calibrated mic ( Dayton UMM-6). Trying to use TuN for the RTA. Appreciate your advice.

7 months later and I now own a MAX and was one of the first to be invited to MAX Certification Training next month. Let's see how well this video has aged.

[@1ohmwrecker]

$3,500 tho!🤦‍♂️ give it up JL. That's ridiculous!

[@CarAudioFabrication]

As stated in the video it's a very high end piece of equipment target towards shops and professional users. Hundreds of shops purchased this the second it was released. For a consumer the fact that they offer USB measurement mic support is pretty awesome.

[@ToeCutter0]

Hehe, only installers would benefit from owning one. If you have a cool installer, they’ll prolly let you use theirs? Update: Annd, only AFTER leaving my comment did I notice that CAF already commented, perfectly.

They are the very best, honestly. And very rare. I've worked at the best audio shop in my city for a year now and I've seen these systems only twice. And one of the systems that I have seen, was only a retuning. It was a 2020 suburban. And I'm being 100% clear when I say the aftermath was truly unbelievable. Full3D sound. It was insane.
