Who learned you how to REW? πŸŽšπŸŽ›πŸŽ€

When I was a youngin, when ever some one said something illiterate we would say "Who learned you how to spoke?". I'm completely REW illiterate πŸ˜” so I want to spark a conversation with some of you fine young/old folks/farts πŸ˜ƒ (jk, dont hang me) about REW. Maybe a why, when, where you decided you needed REW in your life. How you learned, who taught you, how you do it.

I'm sure there's different methods, maybe some one can shoot some of their skills this way. When I got my car back last year from the installer it was a blank slate. I undid the crossovers, re set gains, re-did the input EQ, then I Helix Auto just about Everyting. This was/is new to me. My tune was done in my jobs parking lot before a night shift when I had a lil time. Took a while... half hour here and there for months. Then the finicky UMIK-1 was always cutting out on a constant mid measurement 😑. I'm a busy man with hardly any play time to my self. I got it sounded how I like, but I feel I cheated.

I bought a UMIK-2 a whiles back and a couple weeks ago I started playing with REW. Took a few mesurment just to play with it while I was waiting for my wife to get her nails did πŸ’…. I realized I didn't know WTF I was doing. I brought the Laptop in to the house yesterday to email the pics to my self. I'll post them.

I want to dive in (when time allows) and finish where the Helix Auto tune left off. Hand jerk here n there to see if I can squeeze a lil more out of the tune.

My system consist of rear and front sub. 3 way on my doors, 2 way centre.

I take my measurement in the driver seat waving the magic stick around my face. My TA is also set in between where mine and the wives head reside. So basically a 2 seat tune, kinda. I know there should be an average between both seats but I got to learn to REW first. Plus Fvck her seats response I already compromised my TA.πŸ˜ƒ

This is a measurement with everything playing. I forgot to turn the sub down when I took this measurement. When I did the auto tune I brought the rear subs down to the front sub level.

That hump at 1xxhz wast there when I did my tune but since I didn't turn the sub down I get some rear deck rattles. I think that was what it was. I also tuned my sub flat initially but I didn't like it and after some playing. I seemed to like a peek at 40hz

I took this today in the parking lot before my shift started. With the rear sub at like 1/3rd volume.

NO centre with and withoug the sub up in volume.

I had read a bunch of REW tutorials but I didn't read them before taking the mesurments and I just kinda shot from the hip. Matter of fact I just barely learned how to make the measurement look squiggly instead of like the stair way to heaven.

These are the settings I have set up. I feel like I'm doing something wrong. πŸ˜•

I just want to learn to REW before I dive in face first into hand jerking a tune.

If you gotta story of how you learned, please share. You got some pointers for me, please share. Any input or criticism is welcomed.

Sorry for the long post I'm at work n bored. It's about to be midnight, and I still got 6 hours to go. I'll end it here so I don't loose my progress.

It’s Honda ,

The REW help files are the magic knowledge base

don’t trust anyone on the internet

John the author was very precise and explains things in the help files like it’s a β€œfor dummies” kinda language (exactly what I need because I’m a dummy)

read all of it , don’t just read the topics you want, read it all because all of it is tied together and all
Inclusive to itself….

learn about IR centering, learn about setup, windowing, preferences, analysis, learn the entire thing… read it all …. It took me 6 evenings to do the entire thing.

that was the single best thing for me, know your sample rates and how they affect the measurements, exporting auto eq ,all of it…

you come out of it with a whole new attitude, then download rephase and do some simulations , that will teach you to understand phase and how to see delay in a measurement and such

You’ll make yourself an expert quickly

I would maybe run DATS on that sub and see where fs is , then cross right above that

if it’s high Q fs may simply be too high and means box too small…. Lots of excursion too small box

Or your just beating it up cause it’s fun 🀩

It's an Hertz ml2000.3 it has an fs of 40hz it has .5 cbft sealed. I'm just sending it too much power cuz I like the way it sounds πŸ˜ƒ

Specs are always wrong

It needs to be measured , in the box and in the car

I bet fs is much lower

You can sorta get an idea where run a sweep and at the frequency sound all of a sudden gets loud and stays loud is fs (or abouts very near)
