Not much to say... Soundproofing box for noisy works... Build in MDF and 20 mm plexiglas. Very effective!!!

I'm conducing guitar loudspeaker cabinet fabrication technique research (material type/thickness, mechanical joints, adhesives, etc) and how these relate to cabinet/speaker coupling and enclosure resonance with respect to psycho-acoustics. Basically, does one speaker cab sound better than another and why?

This is an arcade "cabinet" of sorts built almost entirely from OpenBuilds extrusions. Save for a few 3d printed parts, the electrical components, the acrylic panels, and the monitor mount, every component was purchased from the OpenBuilds part store.
