Designs by 3rutu5 - DIY Compact Wannabe B0$E Knockoff - (Visaton BF37) Second Soundtest

There was sort of an obsession with this one as i was a bit fed up with family members showing off their Bose soundlink mini's and me wanting to see how i would go making something so small.

This was a DIY project made out of one piece of 1.2m 8mm Pine from the hardware store, 2 1.5inch speakers, class d amp, cheap passive membranes and some left over spray paint canisters from another project. Presenting the Micro Boombox using Dayton Audio ND65-4 drivers. Powered by a Tinysine 2ch Class D amp circuit. the divider was 3d printed to save internal volume around 5mm thick in a Z shape

Enclosures are tiny only being 0.01cuft each, tuned to 90hz (f3 76hz), sounds pretty decent for 1.5 inch speakers. The design parameters was to create something small but still have bass to enjoy a bit of a chunky beat every now and then, i would have preferred more at the lower end, but when you think about the size i can live with the outcome. This was meant to be battery powered, but due to its size just cant fit it in currently, so now its running of a 12v DC pack.

Appologies, filmed on a Google Pixel 2 XL, with a broken screen and who knows what else is wrong with it.
