The general rule/accepted standard is 12" to 16" inches of port area per cubic foot.
Personally, I based port area on the max wattage going to be used and then design the port with the proper amount of port area so the " vent mach " of the port will not create port noise.
I try to hold the vent mach around 80ft/sec but I try not to go any lower 65ft/sec.
well, for the cvr's...I've got a design for the box i'm making, and the port is 2.5" wide x 12.5" high, so 31.25 sq.in. of port(length is 13.5" i think...tuned to 33 Hz)
Would this work, or have port noise...any suggestions?
youll be fine on 800 rms with 1000 watts if you dont have the amp yet and want to over power them youll be on the boarder line of phils mach speed rec.
I've already got the amp, everythings setup just in a sealed box right now. Thanks sean.
So, for my next setup, 2 12" RE SE's and 1600 wrms...what should the port area be? (same as other box)volume is 4 cu.ft. and tuning is 33 Hz, just more power.
