just wondering .. does a smaller ported box make it act more like a sealed box? better sq? alpine is sayin optimum vented box size is 1.8 Gross volume / 1.1 net volume tuned to 27 hz(i think)... wich is a Really small ported box , which is alright i guess because i dont have tons of room. Back to the tuning part.. what does F3,Ripple, and Fb stand for on this sheet?
sorry its probably hard to read.. clear as i could make it..
Gross box Volume: 1.8 cu ft Slot Vent area (Dimensions) : 19.5in^2 (13" x 1.5") Vent Length: 27" Vent Displacement: 0.4g Cu ft Internal net Volume after subwoofer and vent displacement: 1.15 cu ft F3,ripple,Fb: 27 hz, 5.8 db, 32 hz
