Attached is the freq response, I have to get this 10 dB shelf down and was wondering what the best approach would be passivily. Put a wide notch, sixth order at 2k or what would be the easiest. Has to be passive though. It would be nice if I could get a second order roll off at about 2k. Any advice will be helpfull. No frd. zma. files but I can measure the reponse after filters are built. Thanks for the help. Robert.

If you're planning on using this woofer in a 2-way, then cross it at 1KHz, probably with a 3rd order filter, and you'd be OK.
If you're trying to extend the response out as far as possible, then you'd want to use a parallel notch filter in series with the input to the woofer.
