Thread: SMT Wing Diffusors vs. QRD Diffusors? Effective?

  1. #1

    SMT Wing Diffusors vs. QRD Diffusors? Effective?

    The brochure states they are "game changers". And they are beautiful. They look like works of art.

    Are SMT Wing Diffusors QRD type diffusors? Are they effective?

    I have been in rooms which had these...would love to know more about them. The home listening room was custom built for a guy in the recording studio business.

    If you look at show pictures for MBL speakers, they always bring them along... I wonder how they work compared to the "researched" QRD diffusors.

    Yes, and there is a super high end store near Miami that has a room with them...I think Stereo's room uses some of these in the back as well.

    Matts Odemalm is the gent who runs the show . Rarely travels to shows and is usually slow to respond. So I was surprised that he showed up at Munich . The Marten room was in part treated , and there was a discernible difference if one sat in the row that had the diffusion effect . You could easily tell by moving one row back . Contact him on <matts.odemalm@gmail.com> .

    Has anybody actually heard such dedicated room ? I have a friend who heard such room in taiwan & was told it wasn't good . However some manufacturers seem to like it eg Marten with such dedicated room built by SMT. Surely there must be some justifications for Marten to seek out SMT to build their super pretty dedicated room .
    The diffusers & absorbers seems so easy to build eg Varitune V6 , 24x24x48" with a 6" gap which can be vary with a a plank on rail . Will prob build a few to try on my new dedicated room

    Would be interested to know who you are referring to. There are only 2 dedicated rooms in Taiwan using SMT diffusers and Helmholtz resonators, including mine.
    Only 3 people heard my room:
    - the Magico dealer in Singapore, who based on the listening experience with the Magico Q1 decided to rebuild his full show room with SMT treatment, and to distribute SMT in Singapore
    - the other owner of a SMT room in Taiwan (I doubt he wouldn't like it)
    - one of his friend who wants to invest in a SMT room.

    As in any room treatment, there is a big part of science, but also some art... and luck. You never know how it will sound before building it. But in a game of probability, you have much higher chances to get a poor result with a lot of other room treatment specialist (from my experience hearing tons of rooms before building mine).

    Sure, you can build a Helmholtz yourself. Saving would be very limited, much less than the money you spent in a single of your cables (rather build your cables yourself, saving will be higher!). I prefer the convenience and piece of mind of getting something which has been tested and work (and the opening in the diffuser is a bit more complex than an adjustable gap...).
    Good luck on building Wings diffusers yourself. Their profile is not so straightforward. Assuming you would get all dimensions right, I doubt you would save any money.
    SMT wings diffusers are very unique, because they are the only one who work in the near field (unlike normal quadratic diffusers, they are not only spatial diffusers, they are also temporal diffusers). If you have a 17x 10meters, you can live with a RPG diffuser.... as they would work well if you sit more than 3-4meters from them. In a smaller room like mine, I can sit 60cm from the back wall without any problem. See the measurements of my room and a bit more explanation in the thread "new home for my magico Q1"
