    i just installed a 400w eminence delta 15 pro as a replacement in my swr basic 2 way (1X15") PAS speaker, which had blown out a little while before.. i was using a traynor YBA-3 head, rated at 160w @ 4ohms, at a volume of roughly 4 (out of 10).. so i had another 2X10 cab @ 8ohms connected (making it a 4 ohm load).. and then, after forty-five minutes of playing, the eminence speaker blew and isn't responding to a battery test (which it had done earlier in the day).. is this most likely just a defective speaker? everything, as far as i can tell, makes sense electrically, and i have no clue what could possibly be wrong. thanks in advance for any help.

    Did you check if this Eminence driver was suitable to your cab´s volume and tuning? The Delta pro 15 needs a volume of about 6,2 qubic feet and a tuning of 42 Hz to work as it is intended (in a SBB¤ alignment). That might be your problem. :meh:

    BTW this driver hits xmax with only 50 Watts between 50-70 Hz.

    The DPro 15 should not blow a coil with that kind of power, it's designed to hold up to input levels fives time what your amp can provide. Overexcursion is the more likely culprit, and considering you also blew another driver in the same cab I'd venture that the cab design is insufficient for your needs.

    What's your EQ like? Large bass boost? If so, that's what caused the problem, play around with your EQ and find some tones that you like that don't need a bass boost.

    thanks for the tips.

    i checked into it, and it doesn't appear to be a problem with enclosure design, as my enclosure should match the specs required for the speaker. regardless, overexcursion might in fact be the culprit..

    given the high power handling of the speaker, and relatively quiet [and non-bass boosted] level, it might also be a faulty speaker.. if it was something like blown voice coil, it would have at least lasted longer than forty five minutes.
