Since LGK 2.0 kits are currently shiping and hopefully selling well, I'll add a couple LGK 2.0 crossover photos here in case they are helpful to anyone building this design.
The board size for this assembly is 3" x 4.75". It is crowded and therefore requires some careful planning.
As with any crossover, there are generally multiple layouts that can work. Hobbs' layout earlier on this thread is less crowded and likely easier to assemble (photo on page 2, layout diagram on page 4) but I'm simply showing another option.
As a general rule, my preference is always to lay down the largest inductor and stand up the smaller one. Having the large one laying down makes it more stable, and decreases the chance of its height causing physical interference inside cabinet with a driver or binding post.
Similarly, I prefer to avoid stacking capacitors or resistors on-top of inductors. There is no harm in doing so, but I avoid it unless it's necessary. Just a personal preference. For this speaker, laying down the larger inductor meant stacking components.
Since the larger inductor is still comparatively small, I stood it up which gave room for everything else to lay flat on board. That doesn't mean one method is better than the other, it was just my choice at that moment. Who knows, next time I build a pair I may stack components instead.
The few finished LGK 2.0 cabinets I have seen look very nice. I'm very much a fan of small form factor designs. The boards in the photo above aren't mine and were shipped to a customer. Unfortunately, I can't comment on LGK 2.0 sound signature or performance, but I do hope to have a chance to hear some in person.
Good luck and lots of enjoyment for anyone else building this set.
