Hello all.
I've browsed this forum over the years from time to time but now it's time to post.
I am embarking on a Mark K ER18DXT build with enclosures made from 19mm thick panels machined from solid 6061-T6 aluminium. Planned corner and panel bracing is 19mm square bar drilled, counterbored, and bolted to the panels with an overkill of M6 cap head screws (allen key bolts) from the inside. The only screws visible from the outside will be that for the drivers and the speakon connector at the rear. My initial drawing shows 9mm deep curved surfaces sunk into the inside of each panel in an attempt to eradicate parallel planes within the box. It will be interesting mounting the x-over hardware with comfortable clearance from the aluminium enclosure.
These will be used with a sub. Any advice regarding if I should go sealed or ported, and any words of wisdom on anything that will help for nearfield use would be great. In fact any thoughts/input/advice/critisism/questions are more than welcome.
Initial design:
