Room-Sized Studio Light Speakers Combo -- Episode 431

 

Clem likes to hear Podcasts and Music while working on element14presents videos but he’s not keen on using headphones and does not want to pump the volume to max to hear his speakers across the room. So he turns the ceiling of his workshop into a giant speaker, by building Studio panels. These Panels also reduce room noise for better audio recordings and by adding small LED lights act as soft light boxes for filming. Dragging around big lights with softboxes is not needed anymore for a lot of shots and the right background music helps keep the groove. All in the name of better, faster project videos! Praise the everlasting Din5_180 Connector for its versatility!

  • Hi, by chance I stumbled upon this old video and people were asking for the reference to Tech ingridients Video about speaker smade from extruded Polystyrene.

    My inspiration initially stemmed from a different source.

    My reference to XPS for this kind of setup comes from earlier experiments with building Electric guitar bodies and simiar speakers the concept of mounting transducers to plates of various materials is not so new (its the reverse of the piezo transducer pickup for hollow body guitars. for example. The Video by tech ingridients is really great and I highly encourage you to watch it. My design has some key differences that let them behave differently than his setup. I also had to mount stuff on the pannels which is not ideal for sound to fullfill my purpose of lighting and mounting options (glueing something to the ceiling just does not hold up). I focused more on the light aspects. So if you are more interested in sound check out tech ingridients video https://youtu.be/CKIye4RZ-5k . Props and credtis to him.

    I also have made a panel with those exact Dayto ntransducers and I got to say that both are a great value and experience. Sound wise the Dayton are better for Music (especially high pitched classics) while the visaton are mcuh clearer for Spoken word (podcasts, audiobooks) they have a bit different characteristics, so I placed them at the points in my workshop that suited the use best. Daytons near my desk and visaton in the open area, where I want to hear that content more often.
    also the daytons start to distort sooner but have a higher general volume at the same setting.

    So it boils down to what you want to experience with your audio setup.

     

    the light has proven very usefull on many occasions since I mounted them. and having a non flickering soft  source from above lets me shoot quick detail-shots without havign to set up any other lights.

  • Great project Clem, I really enjoyed it. Seems very practical and a big return for a modest bill of materials. I've done PWM for lights before and fought flicker, but it hadn't occurred to me how inconvenient it would be for a videographer. Also, great timing because I just bought a pair of acoustic transducers but haven't installed them yet - now you've got me thinking about turning them into functional lights as well. I've been fascinated by videos that Tech Ingredients has done on YouTube testing different transducer installations similar to this approach with the Visaton. I ultimately bought a pair of Dayton Audio transducers because they're local to me. Can't wait to try this out. Thanks!

    Thanks DAB! Glad to have earned a fourth star from you!

  • Very good project Clem.

     

    Well done.

    thank you, I learned that the behavoiur in case of sound can be utilized in both ways, if you'd build a membrane to make a cartain frwquency, that membran would also absorb that same frequency(for the most part)
    Most cone speakers can also be used as microphones, Imay try to utilize the panels as microphones in a follow up segment on a future video.

  • Very cool.  Ingenious that the same material I would use to dampen sound you are using as the cone to make sound. imageimage

    Thanks also for addressing the flicker.  I would have probably just put a large electrolytic on it and been unhappy with the result.
