    I have a few Crown itechs powering my EAW dc2s. When i go into their on screen monitor into the ohm page it should tell me how many ohms each side is pulling correct?
    Well one Itech, i have a total of 4, is telling me its pulling 250 ohms and says high. i know thats high but does this also mean there is no draw from that speaker pulling from that amp? This probably means the speakers in that box that are being driven by that amp arent functioning correctly? possibly blown?


    ps sorry about the pun

    Switch the speakers with ones on another channel and see if the strange load readout moves with them or stays on that channel. If it stays there's probably an amp malfunction.

    This would be easily sorted out with a multi-meter.

    It could be the speakers, speaker cables, or the amp.

    Bouldersound is right. Start swapping known working channels, cables, cabinets.
    It should be evident pretty quickly where your problem is.
    If you're lucky it's just a cable problem.

    So i unplugged the box and plugged it into an amp i know is working, made sure all cabling was working and the speaker still doesent put off sound. im thinking the speaker could be blown but doesent feel scratchy or crunchy like im used to. can a speaker blow without feeling like this?

    It sounds like you'll be better off taking it to your EAW dealer, or find a good independent tech in your area.

    Absolutely. What you are expecting to feel is a warped voice coil rubbing in the magnet gap, but there are other ways a speaker can fail. It sounds like the voice coil has an open circuit, a small burned area possibly caused by a signal spike.
