12db/oct in a HPF means that for every halving of the frequency, the output will drop by 12db.

So, even though you have a HPF set up, the speakers are still getting some low frequencies and could be overworked trying to produce bass frequencies. A steeper slope (like 24db/oct) helps. 6db/oct (which is what you get using a capacitor on a speaker) is unsuitable IMO - the slope is not very steep.

Well, I didn't want to confuse him with the slope.... figured he was working with the built in crossovers in the head unit...no choice of slope there.
