Soooooo........

After a long time, having gathered various components and done a successful dumpster dive for a 190x80 cm sheet of 9mm ply, i finally made some first wood dust today.....

This is not going to be a very loud, or hifi, or pretty build, but i'm making use of what i have. I see this as an exercise to extract the best possible performance from a bunch of junk

I am also not aware of any midtops utilizing ppsl loading, so this is a small scale proof of concept. Stay tuned!

I like a challenge.. don't just show us the stuff that works... show us the screw ups that didn't work too and why.

Nice to see someone making saw dust..

If it sounds like a gorilla is trying to escape, turn it down.

So far only handtools have been used..... The speaker cutouts will be done with a shitty electric jigsaw....

Two baffle boards jigsawed freehand. People familiar with the biltema brand will shudder in abject horror
