    Ok, I just broke the speaker of my Mesa 1x15'...
    I'd like to a have super loud sound because the highs are treated with a 2x10' mesa cab..
    Fane collossus speakers seems good..
    Are they?
    Which one would you advice me ??

    1) Be careful here. 15's ain't 15's. Put the wrong speaker in the wrong sized cab, and even a brilliant speaker will sound and perform like garbage. The speaker's Thielle Small Parameters determine the speakers ideal enclosure size, so there's no fudging it.

    2) Assuming you can find a speaker that is happy in the size of your enclosure, you'll have to re-tune the porting. See the ports that let the air escape from the cab? They're not random. They're designed to be a certain length and diameter and are therefore tuned to a certain frequency. It's a very important part of the design of a vented cab and has a huge effect on how the cab will respond in the bottom end, both in sound and speaker cone excursion.

    The chances of finding a speaker that likes the same cab size and porting as your existing cab are virtually nil. Generally speaking, any speaker replacement will require the cab to be retuned. It's actually not much more work to build a whole new, correctly sized and tuned, enclosure from scratch in most cases.

    The exception to this is if you buy the exact same speaker again, or get the damaged one reconed.

    Most of your audience would not know a Fane (good as they are) as a very high % is reading from the usa. Many good choices......

    In Europe.....RCF, Fane, Celestion
    USA....EV, JBL, Eminence etc

    HOWEVER, it is not just a question of pulling out one speaker and throwing in another, it is important to match the speaker to the cabinet. So, my suggestion would be to go back to the manufacturer and ask the question to them and say you need something with higher power or give them your selection and ask if it is suitable for their cab

    all the best.

    What do you mean by broken? Perhaps the speaker just needs to be re-coned.

    There is a hole (1cm) probably made by a drum stand in the tour van..
    And sometimes, the sound of the HP is crunchy as hell, very dirty sound totally incontrolable..
    But sometimes it works... Dont know why, neither how..

    Sounds like you just need to get it re-coned. Perhaps the crunchy-ness you are hearing is caused by your voice coil grinding a bit, which should be fixed if you just get it re-coned.
