    port noise on recones.....

    Ok, so I reconed my subs and now all of a sudden I have port noise. My subs before in the same box had no port noise. One problem may be that I upgraded my amp from 1700w to 2700w. If I have more power, do I need a wider port? If I recone the subs (but keep the same basket and motor) will it change the T/S specs? My box now was built to my original subs t/s specs.

    Sorry im a noob with this but im trying to learn. I searched but didnt come up with anything..

    thanks for any help

    thanks for the quick reply. i dont have the funds for a new box and its annoying, maybe i'll try to seal off the port with a piece of mdf?

    Yes, different soft parts will have different T/S parameters even using the same motor, this can shift around in frequency and amplitude where the maximum vent air volecity occurs.
