    Have you ever encountered any big peaks that no matter how much cut you add, does not measure any reduction?

    • @RAW-CAt
      @RAW-CAt  Месяц назад +1

      Most likely those will be resonances. Check the problematic frequencies using a sine tone and listen, how they sound to your ear.

  • @deathandtexas2016
    @deathandtexas2016 4 месяца назад +1

    I think it would have helped drive the point home on the limitations of 2 ways if you had a basic tune and showed how the drivers summed. Of course, viewers wanting to see more could reference the other videos mentioned. BTW I am loving this back to basics series.

  • @19rc69

    Something else that may help in a two way where the mid bass can’t play high enough to reach the tweeter, is to try a 12db slope on the mid bass LP and tweeter HP and then swap the polarity on the tweeters or mid bass. But you have to make sure your tweeters can handle that shallow slope at the levels you plan on playing your system.

      For example I never knew or got to getting a floor noise and it now makes more sense into some unknown peaks.

    So i have a hybrid system i have a mid bass driver from a 2 way system and then w co axial that has a removable Tweeter that i replaced with a different tweeter they all have a separate ch vut they are firing up into the dash the mid and tweeter would this be still considered a 2 way and also make tuning it a bit weird ?

    You mentioned that we shouldn’t try to fix dips caused by midbass being installed in the doors because a 15 dB boost could damage the drivers, so it’s better to leave it alone. But shouldn’t we at least boost it a little? I feel like any small boost might still help.

  • @jonesaleroy
    @jonesaleroy 4 месяца назад

    Usually 400hz cancelation and 2 to 3k bump most vehicles have some variation of these in my experience. Has anyone figured out the best way to deal with this without eq? I know the less eq you have to use the less chance of compression and blowing out frequency layers with an eq!

  • @kewlbug
    @kewlbug 4 месяца назад +3

    I haven't done a two way really, but this would be sort of my strategy..
    Before any real EQ, Raise the high pass at the bottom to something like 120 or 140 hz.. (electrical). Throw a WIDE +6db boost in the middle dip(because why not). Raise the lowpass (electrical) maybe 1k higher and throw in that wide boost at that knee area.
    After you get it matching the target somewhat THEN do all your EQ with REW. If it does some big -10dbs or something, so be it. You'll need to bring down the level in the DSP some at the end, but as long as final level isn't more than +1 or +2 ish final level, I'm ok w that.
    I would really try not to leave any sort of "gap". After timing and getting them to play together, I'd even boost a bit in the crossovers on both drivers if you think they can handle it.
    I believe the final result after all this should end up a compromise between headroom and quality.

    Can we use back dor speakers to fix the low midbass dip? Instead of a front sub

    • @RAW-CAt
      @RAW-CAt  4 месяца назад

      The 150Hz dip cannot be fixed with a front sub, only the 60-70Hz. If you will cover 150Hz with rear speakers ,it will pull the image back and you will lose the coherent illusion of the center image.

    Excellent video, noob question incoming. When setting target dB for tweeters, you chose 48.5db, but selected 60db for the mid-bass. Is it normal to have over 10db difference in targets for these drivers?

    • @RAW-CAt
      @RAW-CAt  4 месяца назад +3

      You choose the target level based on individual speaker responses. After EQ you level match bringing the tweeters and mids to the same level.

    @AcidDeathRitual 4 месяца назад

    On your note of vehicle noise(here's looking at you non sense in my far right dash, probably from the glass changers), most people would benefit from letting their car to come up to temp and rpm for a multitude of maybe obvious reasons. Along the process I would take a house or sum level engine on/off to maybe pin point where gains can be made with the install if it isn't obvious. EG that 450-700hz must be just the drivetrain and not a panel.
