Currently the best REW tuning guide

[@speedpros]

Raw cat u a beast 💪 your lesson teaching is making car audio even more interesting and I'm still bumbling dummy head at this 😅. If I can just remember the sequence of leveling, target matching, octaves and what may be a dip lol. No joke I've gotten better since you just drill and take your time and explain so clearly. I wanna send you pictures of my set up and see what you think. Finally in the future I can say I'm getting my time and money worth but bess believe many a Saturday night when the neighborhood isn't so noisy I be like man I wish raw cat was here so I can meter faster and not forget steps that's what be killing me and my computer knowledge is not very good but anyways it's fun

I think there might be minor misconception. When generating a target for a given speaker, REW thinks the target is flat because there is no target curve is loaded into REW (it's right there in the dialog in new versions of REW). Once you set house curve in REW to preferred one, REW generated speaker target will follow loaded house curve and will match the one which exported from Excel Sheet pretty well with minor deviation. And to be honest I trust REW math more than Excel Sheet. So what I usually do is setting up preferred speaker and exporting measurement from target. So it can be used as reference in measurements screen if needed. This way you don't need to export individual speaker responses from excel every time you need to make some changes to crossovers. (oops, sorry, it looks like someone already commented about this)

As always great video, thank you for your work. My 3 cents - mostly we loose most of the energy at woofers due to not similiar response which is caused by installation. If you want to push them forget about mounting in doors - panels or ib installation gives the best opportunity to save most of it. The installation issues is the thing that DIYers should consider and think of before picking the equipment - you need to think of what you can sacrifice (cutting the car) and then the output you can expect. I hope nobody does it but if you're going active don't try to set crossover points to the passive 2 or 3 way crossover as a starting point and do tons of eq to match the target cause the system will sound horrible, the way RAW-Cat is showing is the way to let the system breathe where it can and sound magical even with not hi-end equipment. Installation and a plan before work is the key.

[@sibusisomasina753]

Dropping great gems with every video. Thanks man

[@Matteo080101]

14:05 I have to disagree with you Nerijus at this time of the video. You can export rew house curve as. Txt file and load it into your REW preferences in the house curve tab and then you will be able to use the EQ tab with your own house curve which is not flat, then AutoEQ works well too, unless I'm missing something 😃 Thank you for your awesome work 🙏😎

[@RAW-CAt]

Yes, you are right. I just found out about this a few days ago myself👍

[@Tomzuki.]

One thing to note about the targets in REW, you mention that they do not match the targets from JEB, but that is only because you have not loaded in a house curve. If you load in your main house curve in the target settings and use speaker driver as the target type, you can choose the crossovers e.g. L-R4. Using the REW targets has the benefit of being able to adjust the crossover frequency and slope much easier compared to going back to the Excel sheet and exporting the targets again. Also you don't need access to Excel this way

[@RAW-CAt]

Nice, thanks for that👍

[@kgators8345]

Wow, thanks for this. I've never seen it mentioned anywhere before. No more exporting tons of jazzi curves and going back and forth. Cheat code unlocked. I'm sure it's in the REW manual though right...lol.

[@Ac-cj8pe]

I disagree with you, because you cannot get a detailed house curve without tuning sheet in excel

[@Tomzuki.]

@@Ac-cj8pe For making your own custom house curve, I agree that the Tuning Companion is great. Now, you certainly CAN get a detailed house curve without it, people have shared their house curves on Facebook etc. and they work great if they suit your tastes

[@kgators8345]

@Tomzuki. correct me if I'm wrong, but my thought was that I would use the jazzi sheet to generate the overall house curve, load that in REW, then I would be able to use REW to modify individual speaker driver curves without generating those in jazzi and pulling them over to choose new crossovers that better match my response. Am I making sense? Is this what you were referring to?

[@sanekn]

Hello man, like always very cool content, absolutely love your channel. I'm still trying to find a good house curve. I like detail and I like a very proeminent bass. Right now I'm at the point where I have a good system but still I find the twitters being fatiguing. I love my Sony system in my home, smooth but detailed highs, very nive bass but not muddy at all. Trying to do it in the car but didn't had luck yet. Close but not exactly what I love.

[@jonesaleroy]

Hell yea! New RAW VID! ❤

[@jamesrichard6815]

Such great content your work is going to help out thousands of people. I am currently looking for mi range drivers and your mid-range shootout has helped me a ton. I think I narrowed it down to the One Audio 3wb.e. Someone suggested it to me on DIYMA and I checked out your video on it and you had really good things to say about them.

[@justinmcduffie5863]

Keep Them Coming Bro!!!

[@jperezg]

I love your videos 🤜🤛

[@jonesaleroy]

Yea, I'm with you RAW on the house curve. I usually tune flat to 20k then pull some out by ear till my ears are happy.

[@RomanRW]

Díky!

[@19rc69]

EPY curve is Erica’s initials. She took over Jazzi’s spreadsheet for a while and made some really nice improvements to it. She has a very good build log over at Diymobile. I use her curve sometimes but I add a little more bottom end.

[@Smarmellatore]

I agree about the highs, I tried using some of the house curves that cut the highs but the music always seemed not bright and came back increasing them

[@Nightjar726]

I personally prefer a bit more , with a rise starting at around 350hz because of road noise. With the car stationary , yes I like less mid bass . But while driving the road noise covers so much , that adding mid bass helps That’s my opinion of course. Thanks so much for your great vids!

[@jonesaleroy]

Yea, that 2 to 6k region can get rough with loud heavy music. Especially if the driver doesn't have enough damping.

[@jaskiratsingh6507]

Another very good video !

[@GradyJarrell]

New sub here, your videos are fantastic! I trust your information more than most. You have the same taste in audio as I do, I’m currently installing a 3-way system with sub in a 3rd generation Tacoma. Trying to figure out how to get mids somewhat on axis. Doing tweets on a pillar.

[@lukasproestler]

Nice video, very helpdul! Could you explain how different electrical filters affect the phase? For example if my midbass needs a 12dB electrical high pass to reach the 24dB slope and my midrange hits it perfectly with a 18dB low pass. Also, can you mix different electrical crossovers and frequencies for 2 midrange drivers or should you always go for the same electrical crossovers and slopes for equal drivers? Thanks!

[@RAW-CAt]

What matters is the acoustical response and slope. If you have 24dB LR acoustics slopes you are all set. The electrical crossovers don't matter much. Left and Right drivers can have different electrical crossovers.

[@rajasekhar9840]

Excellent 👏 Loving these videos soo much. Do you plan to show tuning video for front Sub as well? And I'll also be waiting for a 2 seat tune. Keep going strong 💪

[@RAW-CAt]

Not planning a 2 seat tune. Here is about the front sub: kzbin.info/www/bejne/Y2StnIWpfd15aKs

[@kempfchristopher]

Can you please follow up with links that show where all house curves can be obtained?

[@kempfchristopher]

Please disregard. I saw you answered this on your reply to @NorwalkNSKiosk.

[@elviscaragea4433]

You should make some "pro" videos only for your patreon

[@denkudryashov1740]

Fine explanation. The only question from me is why everybody always choose LR24 slopes in the targets? I know this is recommended because of flat summation. But real drives often provides more steeper response. What if I choose more steeper target? After all, with correct EQ i will be able to make correct owerall response, isnt that right?

[@RAW-CAt]

If you choose a steeper target you will have a difficult time to pull all the responses together. You will have very little overlap and potentially some drivers won't reach each other.

[@NorwalkNSKiosk]

Could you please add links for the other house curves?

[@Ac-cj8pe]

If you have dsp and active system you definitely need a calibrated microphone. If you don’t have any of calibrated microphones you have nothing.

[@RAW-CAt]

Yes, That was covered a few videos ago when talking about moving microphone method.

[@KaranDeep-e4c]

How about tuning with a xlr microphone and an audio interface ?

[@RAW-CAt]

@@KaranDeep-e4c the method is exactly the same.

[@kewlbug]

Nooo dude. why are you guys still using Jazzi?? Literally just select your main target file as the "house curve" in EQ window.

[@RAW-CAt]

Because no one (and I am looking at you) showed me that😉

[@kewlbug]

@@RAW-CAt Hey, that just gives you new content for later. lol

[@RAW-CAt]

​@@kewlbug True😅

[@19rc69]

@kewlbug Wait I’m confused. Do I need Jazzi’s sheet or not? I still need to generate a custom house curve to use in REW correct? I’m not talking the individual driver curves, but the main overall “house curve” that I want my whole system to follow. I don’t know any other way to generate it other Jazzi’s sheet.
