This is a speaker upgrade for the Bowser Dual Cube style speaker found in many models (Bowser part #1291). We’re calling it the “Bowser Universal 1.” Please check photos and dimensions for correct fitment (35.5 × 16.5 × 10mm). Our speaker upgrade kit is a vast improvement over the factory unit, with much higher volume, more bass and better mid-tones. There is no cutting or modification required to the model; the speaker kit simply screws into place with the factory hardware.

Like with all our speaker kits, a 4 ohm resistor is included to wire in series for non-ESU installations.
