Contour Enthusiasts Group Archives Forums Modifications Audio What equipment are you using?

Well, from other posts I have determined that the cabin gain from a contour has to be somewhere around 18 dB. I have a sub with a 88 dB 1w/1m sensitivity. 400 watts going to the sub in a sealed box with a Q of .8

Sensitivity 88 dB
dB from power 26 dB
Cabin gain 18 dB
dB from box design 0 dB
Total 132 dB

This is obviously theoretical but should be pretty close...
