This was more like it would start it's excursion, then die down to about half way and finish the bass note.

1. HP-LP-AP dip switch (I have it set at LP-Low Pass)
2. Frequency cut off potentiometer
The potentiometer goes in incrementes of about 25hz. I have mine set to not play anything above 55hz in my sub.

Did you make sure you have no leaks in the enclosure?

try turning off head units low pass crossover and only using the low pass on amp
what are the settings on your amp for low pass choices?

Last but not least, maybe the sound of this subwoofer isn't for you. Like you said, you are kind of into the very deep and loud bass. RF has always delivered this with their subs. Boomy loud , internal shaking bass that sounds good. I'm also into that bass as well and sometimes my jl w7 leaves me wanting more. But my w7 sounds good with most music and gets loud enough for me for right now.
One thing i use to read about FI Q series subs is that some people weren't happy with the sound until a week or two after the sub broke in. They sound it gradually sounded better. Maybe you can try this before you resort to buying something new.

LP on amp is already enabled
The sub amp only has a potentiometer that gives you the ability to pick the frequency cut off point. I currently have it set to filter out everything above 55hz...
