Well since it wouldn't let me post in the thread I'm posting my reply in a new one lol.
The adjustment changes the tuned length of the pipe. Lengthening it will make the resonant pulses long and weak making more low to mid power, shortening the pipe length will deliver shorter/stronger resonant pulses resulting in more peak power. A very neat idea, but I've never done much with the LRD adjustables.
