    The polyfill insulation should not be blocking the ports. You didn't mention the type of subwoofer that you own. Maybe if you give us a few more details, someone will chime in to assist you with your issue.

    Once you have moved the polyfill away from the ports on your subwoofer, you might want to try placing the subwoofer in a corner - where the performance should be increased some more.

    I second not blocking the ports with insulation. If you are adding your own insulation or messing around with the stuff that is already crammed inside, make sure to leave cooling space for the power supply/amp. Do not cram insulation around the amp either.

    thanks [​IMG].
    i have a KLH 10inch 100 watt sub its a cube design uhh has ajustable crossover from 40hz to 180hz but they say it can go to 30hz aswell i dunno how that works the polyfill is like glued over the port on the sub i havent taken it appart yet so i dont know if there is anymore polyfill in there. and as for the port noise i was curious if putting polyfill over the port stops that. because my sub doesnt do that, but ive had otehr subs that did when there was no polyfill over port ..... really i want to know is it safe to and or better to remove the pice of polyfill thats over the port?

    oh ok thanks [​IMG].
    they say that a sub that has responce under 80Hz you cant tell where its placd but my ears are sensitive and i can tell where a sub is in a room nomatter what unless its directly infront of me or if there are multiple subs... so my problem is i like how when i put the sub in the corner its louder at lower amp levels (less heat for the amp) but when its in the corner i can really notice the placement right now i have it under my TV is ther eanyu ways i could fix my locatin problem? (sorry if i dont make much sence if needed i can retype[​IMG] ) thanks for any help
