Need to kill some frequencies

[Cuseikan]

I was just wondering if their is anyway to kill, or at least minimize certain frequencies. I was thinkining of useing the Memphis 16-EQ50. Dose anyone have any exp with the Memphis 16-eq50?

Here's a link. I have a 7 band EQ on my HU but it only controls my door speakers(and dose a good job at it). I occasionally listen to rock, and I get a bad wobble from the subs. Will this help to eliminate any unwanted frequencies. In example, my box is tuned to 28Hz, and I really don't prefer any bass above 45Hz. Can the 16-Eq50 help to eliminate those frequencies in songs above 45Hz. Or at least minimize them.

And if this won't work what will?

I know you can pu the low pass filter on the amps. I just want something I can control up front.
