  • Quickstart guide link is broken :(

  • I have one of these that is also 8 Ohm 0.5W the only difference is that it is half the size in diameter, but 20 mm height. How much of a difference will it make for me?

    • I’m no expert, but in my simplified understanding, a smaller speaker (at least this type) renders sound less accurately, especially in the low frequency range.

      I think the reason for this, at least in part, is that as the physical size of the sound wave gets larger than the physical size of the speaker, the sound waves get distorted because they cannot be fully rendered with a small speaker.

      So, your sound quality should be lower with a smaller speaker. How much lower– I’m sure– is debateable. I don’t know if it is as simple as: your speaker diameter is 25mm, so the lowest accurately rendered frequency is 13720Hz; if it were 50mm, it would be 6860Hz? My gut says it’s more complex than that.
