Arteluthe special project (full aluminum speakers) is moving with full steam ahead! Panels are mostly machined, except for the various openings for port, drivers and connectors.
In last revision before “D” day they’ve decided on a reinforcement panel with a twist. “The twist is that the panel is 0,010 smaller than required and holds side panels with a constant tension, as if the speaker was held with clamps, giving further strength to the assembly. Probably very, very overkill.”
