Yeah makes sense...Vent performance is all about airflow. The less you restrict the airflow, the better off you are.
You want to avoid things like:
1. Sharp edges, round over your corners
2. 180 degree bend, use 90 degree bends if you can
3. Anything protruding into or otherwise obstructing the port, don't run your wires down your port either.
22 m/sec is just about my cutoff for home audio use. If you could get closer to 17 m/sec it would be better, but then your port would have to be even longer and you probably don't want to do that.Velocity is pretty low.
Peaks at 22.3 at 16hz
1st resonance 127
Dont have a router so cant round off anything
hmmm I just sold my router ha.22 m/sec is just about my cutoff for home audio use. If you could get closer to 17 m/sec it would be better, but then your port would have to be even longer and you probably don't want to do that.
The general consensus is you want to cross over at least one octave below your first port resonance, so as long as you are crossing over around 60 hz you should be fine.
You don't need a router to round things over, its just makes it a lot easier! You can remove the bulk of the material with a rasp and then finish off with sand paper. It IS worth the effort.
Yeah makes sense...
Real question is can I get away with multiple bends?
Am making a narrow cab, was hoping to use 2 vents that are about 56 inches long.
If I can get away with 3 bends this would work...
Hoped to run them as window braces almost...
Front-Back (about 13")
Bottom - Top (about 22")
Back-Front (about 13")
down front (about 8")
Thanks - Heres the info I was provided:Do you have a link to the design? I'd like to take a look.
