Introduction: Victrola Style Passive Speaker
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.
