I really wanted this excavator to have proper sound. Deep and powerful bass. Not toy-like. I looked around a bit to try and find a large speaker that would fit, but came up empty. So I printed one instead. My biggest print to date. 21 hours and 290 grams of ABS. :-) (25% infill)
The speaker driver is this one:
-
Pioneer TS-G1045R 4-Inch 210 W 2-Way
On the back there is a speaker terminal that I bought on Ebay:
-
44.8x21mm 2pin Red and Black Push Type Speaker Terminal
And then there are four self-tapping screws in the front, two on the terminal, and three that fasten the speaker box to the base plate.
I cut off the mounting tabs on the speaker driver, because I needed the screw holes to be closer to the cone. The flange on the self-tapping screws is now what holds the speaker driver in place:
Soldered the wires that came with the speaker to the terminal:
Attaching the speaker box to the base plate with three self-tapping screws. I added a soda can too, as I've seen a few others do that lately. My build is dwarfed by DADSGARAGE's and Cooper's though, but still it's not that small. :-)
