I will like to compare the efficiency of the same sub in two different enclosures. Lets say you have a AE AV15X driver in a sealed 4cf box and then decide to use the same driver in a 8cf PR/ported box. Lets say you are using 1,300 watts to power the sub.
My question is, what will be the efficiency of the sealed vs the PR/ported box? Will the bigger box be 3db's more efficient? Also, how will the power of the amp play into the equation? The sealed box might use the amp's full power through the frequency range (within xmax), while the PR/ported box, due to its efficiency might not take the full amp's power in the low-bass without going past its xmax.
So you lower the amp's gain to produce, say, 650 watts to keep the sub within its xmax at the low bass and use a high pass filter below its tuning. You will gain low-bass vs the sealed box but will loose headroom in the mid-bass due to the low tune of the sub and the fact that you're not using the amp's full rated power, right? Correct me if I'm wrong.
