I'm going to have a 3.434ft^3 volume tube and I want to know what frequency I should tune it to. Patrick Sun :
"The tune might be asking a little too much for a 6 ft^3 enclosure for the 15" Tempest driver, and I might pick up more port noise than optimal, but I'll get to see how adversely port noise will affect the overall sound quality of this subwoofer in normal operating conditions. The reason I choose 16Hz as the tuning frequency is to provide as much driver protection with such a low tune. This is because the driver is "unprotected" at frequencies underneath the tuned frequency of the box/enclosure, so by going with 16Hz, it's protected for most low end frequencies while sacrificing a bit of output near the 20-25Hz range. But for a subwoofer this small, I can live with a few less dBs of SPL (Sound Pressure Level) down in that low end region."
So... any suggestions?
