My system is:
2, 12" Assassin subwoofers
1.25 ft^3 each, sealed box
Profile AP1000M (500W RMS x 1 @ 2 ohms)
in the trunk of a 1999 Honda Accord facing the tail lights
WinISD says they peak at 117dB @ 60Hz (f3 = 40.4Hz)
What do you think I'm actually getting?
If I go to a ported box, 3.5 ft^3 combined chamber tuned to 32Hz WinISD says 120.3dB @ 54 Hz (f3 = 34.5Hz)
How accurate do you think that is? Am I really going to get 3dB for 'free' just by making a new box?
