    Hey folks, first post here in this forum. I just finished putting together my sonosub with a Tempest and the AVA250 amp. I will say, compared to my Polk Audio sub, this thing kicks the living cr*p out of it! Of course, that's not too hard to do being it was a very whimpy 8" driver in a small ported enclosure. One of the first DVD's I popped in based on what I've read was the Finding Nemo scene where the girl taps on the tank and my-oh-my, it about shook the walls of my house down! Now THAT was a test! I am not in the least disappointed and thanks to Brian Bunge for the order and responsive customer attention.

    But, I am a perfectionist and I have this nice little (actually, 3dB is hardly little) room hump that I'd like to eliminate. I have modelled it in lspCAD that it can be compensated for with a -3dB EQ at 50Hz and improve my flatness. But, the question of the day is a circuit or other recommendation that would do the trick?

    Thanks,
    Steve
