TLDR Using 3D printing and modern techniques, it is possible to build exceptional speakers with improved sound quality and complex shapes for subwoofer frequencies.

Key insights

  • 🎶
    Building exceptional speakers requires more than just simple boxes, and 3D printers may be able to help with their ability to make complex shapes with millimeter precision.
  • 🖨️
    Printing only a hollow shell for the speaker chamber and using it as a form mold can result in speedy print times and reduce the amount of filament needed.
  • 🔊
    3D printing can now be used to create Hi-Fi sound quality speakers, thanks to the ability to make complex shapes and utilize modern techniques.
  • 🎶
    Using software like horn resp can help calculate the required dimensions for exceptional speakers, even for small drivers like the three inch unit from Tang band.
  • 🎵
    The Tang band mid-tone driver chosen for the speaker project has the unique ability to cover high frequencies as well, making it a versatile and cost-effective option for those on a budget.
  • 🔊
    Using a digital signal processor can provide advanced crossover and specific processing for each sound output, improving audio quality in speakers.
  • 💻
    These small speakers can sound significantly better than a sound bar and even trade blows with high-end bookshelf speakers.


  • How can 3D printers help in building high-quality speakers?

    3D printers can assist in creating complex designs for speaker enclosures, improving sound quality, especially in subwoofer frequencies.

  • What materials can be used to fill the hollow shell of a 3D printed speaker?

    Plaster of Paris can be used as a filler material, but adding PVA glue during the mixing process is necessary to reduce brittleness and improve sound quality.

  • How can internal reflections in speaker enclosures be dampened?

    Adding soft materials to the enclosure can help dampen internal reflections caused by thick chamber walls, reducing distortion.

  • What software can be used to calculate the dimensions for a folded speaker configuration?

    Horn Resp software can be used to calculate the required dimensions for a folded configuration of a speaker unit, which can then be 3D printed.

  • How can the aesthetic appearance of the speaker enclosure be improved?

    The visible joins can be filled and sanded down, plastic primer and textured paint can be applied, and a wood veneer can be added for a high-end appearance.

Timestamped Summary

  • 🔊
    3D printing and soft materials can be used to create complex shapes for speaker enclosures that improve sound quality, particularly in subwoofer frequencies.
  • 🔊
    Building exceptional speakers using modern techniques involves using software to calculate dimensions, creating a three-section design with a subwoofer driver and 3D printed boundaries to save space and redirect energy.
  • 🔊
    Building exceptional speakers using modern techniques involves designing smaller parts for printing and gluing them together using h-clips to reduce printing failure.
  • 🔊
    Building exceptional speakers involves adding internal air guides, sealing up holes for wires, using a hollow forming technique, adding dampening materials, and creating a pore with plaster of Paris powder.
  • 🔊
    Improve speaker enclosure appearance with sanding, primer, paint, and wood veneer, and create airtight seal by using M3 threaded inserts, correct polarity, and blue tack.
  • 🔊
    A suitable mid-tone driver was chosen after days of testing, with the Tang band unit being selected for its smooth sound output and ability to cover high frequencies, while the design allows for the addition of dedicated tweeters and the option for a grill cover.
  • 🔊
    Building exceptional speakers using modern techniques involves adding side baffles with magnets, using a digital signal processor and amplifier, 3D printing a box, and programming with Sigma Studio software for optimal audio quality.
  • 🔊
    These small speakers have deep frequency response and rival high-end bookshelf speakers, making them a great alternative to sound bars, and the speaker design is easy to build and competitive with manufactured units.
