With the woofer enclosures now looking pretty good it was time to tidy up how the compression driver is supported, and tidy away the LPAD and protection circuitry.
I got some small pine boxes of the right size (from ETSY seller HIPROGRESS. I stained this the same colour as the speaker boxes, and got some self adhesive 4.5mm neoprene sheet from Clark Rubber to act as vibration damping, and protect the finish. This acts as a nice firm bed for the compression driver.
