Thanks
So, as far as improving the DD, it’s theoretically possible. In
theory, since the board was centered directly behind the DD there
could have been some unwanted reflections off the crossover board. And removing that board would remove the reflections.
But that’s just abstract theory and conjecture. The reality was that I was unable to hear any difference with the board in the stock location vs vertically off to the side. If there was a difference, I imagine it would be very small and difficult to measure without sensitive and expensive lab-grade equipment.
I think it’s much more important to make sure the capacitor is soldered properly, and that the wires are wired consistently on both sides. Because if either of those things aren’t right, there
will be a difference.
