I got my K5’s installed. I am using 1/2" line as suggested, but notice that when using a barb fitting that it’s going to restrict the airflow a bit less than 1/2". I have a regulator just before the horn to bring the psi down to about 115 as to not wear out the diaphragms prematurely. Is this the best set up? Am I loosing much volume because the line is restricted with the barb fittings? Any thoughts on this? The thing seems crazy loud, I just want to be sure I’m getting all I can out of my set up.
Yeah, the fittings are always going to be a restriction (compared to the hose or tube).
But anyone else that has upgraded to 1/2" I.D. hose has the same situation.
You’re good to go.
