December 4, 201113 yr Author Keep in mind when you are looking for low frequency extension you can't just look at Fs. You have to consider Fs in relation to Q as well as the enclosure among other things such as power and displacement capabilities. Even if the Fs is reasonably low in frequency but the Q is also very low, you are running them pseudo-IB in your door and their displacement is fairly limited.....low frequency extension is still going to be limited. It's a simple fact of physics. Another thing to keep in mind that is B&C's rated Xmax is 2-way not 1-way because it's total coil overhang. The moral of the story is that you will have a difficult time finding a pro audio style driver with decent low frequency extension in the type of installations we typically perform in car audio. It's a basic compromise of their design, there is no way around it.Thx, that being said 80% of the car speakers out there dont impress me either including some of the mega buck units
