WebSep 13, 2024 · In the ported design I can get the port air velocity down to about 30-35 m/s, which I think is pretty good for that much power. I'll be using a 20Hz HPF or something to control the xmax to 45mm. Now I have tried to design a series tuned 6th order in hornresp. I have a start with 160l front chamber and 80l rear chamber. WebMay 26, 2014 · 05-26-2014, 12:38 PM. Re: WinISD vent velocity? Velocity peaks just a tad below tuning at about 37-38 m/s, at 25Hz it's modeling to be around 14-15 m/s using the 4 4" ports and a 4th order Butterworth high pass at 15Hz. Xmax is exceeded by about 2-2.5 mm at 13-14Hz and then again at 25-26 Hz at full power.

WebFeb 17, 2024 · This is a combination of empirical observations and the science though. As I have understood it the science predicts an air velocity in the port, but... WebThe solution is to replace the vent with a passive radiator. This is a driver unit of the same size or larger than the main woofer, but it has had its motor structure removed. It becomes just a passive diaphragm driven by the air inside the cabinet. The mass is chosen to match the equivalent of the mass of air that was in the vent, but because ... df025 preheating unit diagnostic connection

I think a hardware EQ between the amp and sub is the solution, and to be honest a hardware EQ is probably a useful ... WebJul 23, 2024 · This leads to chuffing at low frequencies and loud volumes. That's where the port air velocity limit of around 20 m/sec comes in to play. Keep the port velocity down with a big diameter port and you won't have chuffing … church\u0027s chicken in texas city
