[QUOTE="SlugButter, post: 8796087, member: 678073"] I do notice port noise when standing at the back. Not audible up front. Mainly from 35 HZ and below starting a couple clicks below full tilt. Since I have the ports next to each other it’s hard to tell which port it’s actually coming from. That’s one downside to this design with ports side by side. With this many bends in the port, I thought it could have a little noise from the port velocity in modeling. I usually account for number of bends in the port and add it to velocity, but the port was already 48 inches long, so I tried to skimp. Since I’m rebuilding it with birch and plexi, I will add another 10% to port area and adjust the overall profile to be a little larger. Its likely from the low tuned port, since the higher tuned port is just one bend, and is far over standard port area per sq. ft. [/QUOTE]
