Tuning options DR200's
Posted: Tue Dec 15, 2020 1:03 am
Just a DR200 build questions.
I'm building 2 x tuba30's and 2xDR200's. Keeping a 1:1 ratio.
i have searched the forum for info on the tuning options on the DR200's. In particular the port sizes.
Assuming i want to crossover below 135hz (someone can tell me where the sweet spot is between the DR's and the Tuba), i'll be using the 2"x1/4" option.
I'm a bit confused.
on page 19 it mentions "The hole diameter depends on your duct configuration, which is covered later in the plans (Tuning Options)"
but by page 35 it says "Make the ducts from 2” ID Schedule 40 PVC pipe."
my first interpretation was that it was going to be a 1/4" duct 2" long but from later now i'm thinking it's a 2"duct 1/4"long.
I know it's probably plain but for some reason my head is not letting it be.
Any thoughts on that (not my head)..........
Cheers
