Victrola Style Passive Speaker

BUILD: Passive Amplifier

Surprisingly effective passive amplifier. 11db increase in volume from across the room, better bass, and a bit of reverb.

  • Cone is made from 2 file folders joined with CA glue, and coated with truck bed liner
  • Tube is a 2" p-trap with a 2" thread adapter and a 3in flush fit cap, painted with hammer texture paint and then metallic oil-rubbeb bronze
  • Mounting bracket is 5/8" aluminum flat stock
  • The back plate and phone slot are just from some scrap 2"x10" pine I had lying around.
