What does that mean? The frequensy on one set is 2.400 and one is 2.500Hz is that a big difference. Also slope one is 12/12 dB/oktave and the other is 12/18 dB/octave what does all that mean?

http://www.bcae1.com would be worthwhile reading :)

The slope is simply how steep the curve of the crossover is - 12dB/octave means that after an octave (doubling the frequency), the signal is attenuated by 12dB. 18dB/octave would be attenuated by 18dB after an octave, and so on...

its like different gear ratios in a car gearbox. they have to be set right or you get bad performance.

do some reading on car audio forums.

There is no ultimate "which is better"...it depends on your install and speakers.

There is a better, it just depends on for what. And in this case, the least of what the what encompasses is the driver choice.
