Thanks for the reply. Still not clear though.
But, after a fair amount of searching, I believe I have found
the definition that answers the question.

6 dB, 12 dB or 18 dB SLOPE
There are different rates for the reduction of power, called SLOPES. The most common are 6 dB, 12 dB and 18 dB slopes. (dB=decibels) A 6 dB slope will reduce the power at a rate of 6 decibels per octave starting at the chosen crossover frequency, creating a gradual slope of power reduction. The 12 dB and 18 dB per octave slopes work the same way except that a 12 dB slope has twice as much reduction per octave as the 6 dB slope and an 18 dB slope has three times the amount of reduction, thus cutting off the unwanted frequencies three times as fast.
I contacted Pyle who said the switches controlled bass boost, but without a model # I was not
getting specific answers. And this didn't make sense as these were a boxed set and boosting
bass to a tweeter is contradictive.
So I guess the answer is really to obtain the best sound, of course. Using the 6db selection on
the tweeter may produce a sweeter spot, though only if the tweeter can handle it. It would
be safer to use the 12db to be sure not to burn out the tweeter.
However, since I'm not mixing/matching components, this 'boxed set' from the manufacturer
one would assume you could select either setting for either driver and be safe. But on the
other hand I think it would also apply to how much power your running. When I do install the
amp, then perhaps I should be more concerned about burning out the tweeter, but for now
just driving them with the deck, I should be ok with either db setting based on my taste.
