Sanway K21 subwoofer speaker and Sanway A15 loudspeaker. Models with holes can be connected into a stack using the peg for connecting the same type speaker or the angle-peg for connecting the A15 to the K21. Pictured are the individual speakers as well as an example of how to stack them, and an example of the concert-style speaker stack that it's based on.
Printed at .15mm layer height with brims, support for angle peg. Print peg & angle-peg at 100% infill to reduce likelihood of snapping off when attaching speakers. Artifacts in example prints are likely from printing in silk PLA, not present in model.
Handles are from ronnskull's PA speaker model https://www.thingiverse.com/thing:3847987
