4 Rockford Fosgate T3 19 on 4 Sundown SCV 7500 19hz demo

Another one, same song but better filming. Subs move nice, but get hot really quick above 30hz. Rise is lower at peak than at 22hz, go figure, so subs see 6kw plus above 30hz and get super warm, as 6kw plus is alot on high freq even for a 5" coil, but they do take it well for short periods. Enclosure is a 6th order. Specs: Rear chamber: 772.2 litres excluding sub displacement (27.267 cubes) subs 0.34 cubes per sub so minus 1.36 bottom chamber is 26.31 cubes net 6.577 cubic feet per sub rear port 133mm deep 1350 wide 278.2 sqaure inches, tuned to 25 hertz front port is about 780 sq/in, tuned too 50hz. front chamber is about 28 cubes from memory. plays 15-65hz well, 17-55hz very well.
