How to adjust tweeter height

  1. I bought some Cinder/Besser (concrete) blocks 7.5″ x 7.5″ x 15″ (AU$3.60 each)
    & spray painted them satin black.
    My DeVore Fidelity – ‘Orangutan O/93’ floorstanders are exactly 15″ wide & so,
    they match the width of the Besser blocks perfectly.
    With the four IsoAcoustic – ‘ISO-Puck’ isolation & vibration absorbing ‘pucks’
    in between each of the two O/93’s & the black Besser blocks, my ears are
    now exactly in between the tweeters & the mid/bass drivers, when I’m
    sitting in the sweet-spot…right where they should be.
    Alternately, I could’ve just gone & bought a black, corduroy beanbag 😉

  2. Tilting speakers slightly back is said to time align the frequency response. Tilting it forward can make time alignment worse. If you have mini monitors you can just buy speaker stands with the correct height to solve that. Floor standing speakers are usually good the way they are and have tolerances built in.

    1. Joe,
      Reputable loudspeaker companies will time-align their products
      (drivers) & sell them to customers ‘as they stand’.
      I doubt that Wilson Audio, etc. want customers to be tilting their
      I’m pretty sure that John DeVore has time-aligned my O/93’s &
      so I keep them untilted; just raised.

      1. Agreed, I never tilt them forward or backwards. Like you said good quality speakers already accounted for time alignment built into the cabinet and crossover design.

  3. I noted that the question came from a listener who sat in a sofa. I find when I sit in a large soft seat that I lose some openness and highs probably due to absorption from the soft seat. I find a smaller seat that with lower back and without soft covering much better for fidelity. I do recognize that often a system is in a living room and the furniture often rules but try my recommendation if you can.

      1. It may even be worse for young people, at least those who haven’t damaged their hearing with loud sounds. They are still capable of hearing the highest frequencies which get absorbed so they would notice the absorption of these high frequencies, the ones us old guys don’t hear any more so the change is less significant for us.

        1. Well, I can only hear to 13kHz, & if I put a pillow
          behind my head when I’m listening in my bed to
          my bedroom system, then there is a marked
          drop in the higher frequencies.
          I can only speak from my personal experience.

          1. I didn’t mean it wouldn’t affect most of us just that those lucky few with a full 10 octave hearing range would hear a greater change than the average person. I doubt I hear above 10 kHz and hear the affect easily which is why I made the comment. Not all seats are good for critical listening.

              1. I’m older(80) so I guess I think I’m basing it on what I read about hearing. It’s too long ago to remember. But I suspect unless one’s hearing has gone really bad you still can hear well enough and can still compare what you hear live versus what you hear recorded. Thank goodness, otherwise I’d lose a hobby of over half a century.

  4. I’m sorry everyone.
    I’m not exactly a rocket scientist, but you don’t have to be one to know this.
    There is no such thing as a peel that you can take to make you taller.

  5. My B&W 800s each have four adjustable feet similar to those on the FR30s. They are threaded so are infinitesimally adjustable. I have my 800s tilted slightly forward in order to angle the tweeter axes such that they project to about ear height at my listenening seat. A serendipitous byproduct of this is that it slightly lowers the soundstage such that the performers now sound as if they are at or just above floor level. To me, this provides a more ‘intimate’ connection with the performers. 🙂

  6. There are pills to make you taller, at least Grace Slick believes so.

    One pill makes you larger
    And one pill makes you small
    And the ones that mother gives you
    Don’t do anything at all
    Go ask Alice
    When she’s ten feet tall

    Just sayin’
