I'm used to the ol' 80 Hz home theater type cross over, so I was thinking that the "lower" the better too, but didn't see anything that did that.
The sub amp does have a crossover, so it can filter out the highs just fine.
The sub amp is just a Pioneer GM-7300M and the sub itself is a 10" Pioneer TS-W251R. I don't recall the 6x9's but they were again Pioneer brand but I bought them about 7 years ago and they sat in the box for most of those 7 years. The fronts are unknown right now as the dealer hasn't called me back yet today to let me know what they are, but that is besides the point.
I'll look up the 6x9 specs tonight to see, but I think that they claim a frequency response down to 28 Hz. I just don't like the sound coming out of them down that low, and it doesn't have enough "punch" like the sub will ad.
