Ok, Ive already started working on my box, but I have been experimenting with different port lengths. I listen to mostly rap/hip hop, and this is a chart from WinISD. The red line is tuned at 36.6. The green line is tuned at 32.2. The green line plays lower bass, but the red line has more gain. The ports are shorter with the red line. Which would you suggest? I like the punch factor of bass, and this is for a daily driver, for daily music.
