BOOZETOOTH SPEAKER MK9 (DIY SPEAKER AND 3D PRINTING PROJECT) - TEASER

Just a quick video, shot by a dodgy phone as per usual....Not complete but a milestone\progress video after some lengthy CAD designing and a few wasted prints. TLDR.... taking MK8 and cramming a 2x50w 12v amp and 3s power supply into it....be interesting to hear how it sounds.

As a few of my other videos have shown, i've been a little fixated on designing my own variant of a portable battery powered speaker. Finding the right components is always difficult, especially when you dont want to sacrifice any of the design intent (ie size). I really wanted something that resembled a beer can and have modelled it based on a 500ml one, although it might be slightly taller. I've done a few in the past with passive radiators and 18650 batteries and i think the reduced internal volume really makes the bass sound thin. This one will be using a 10mm port and a smaller battery/components. The bottom is a screw thread to make accessing parts easier if something happens, but different to the MK8, the top will slide in and have two bolts to secure it, where MK1-MK6 relied on gluing and hoping nothing would go wrong.

Also to note, MK8 is fully painted and had test runs already and sounds pretty good, just trying to get all the parts in as originally intended.

Parts list

2inch Peerless full range driver - PLS50N25Al07-04 (from a google home device)
502L MINI 2x50W TPA3116 bluetooth 5.0 AMP
3s BMS
3x 18350 Li-ion batteries.

hopefully i'll have this wired up and painted over the next few weeks, will post more once it is....providing it isnt crap :)
