a newbie type question on speaker power ratings...

    it's one of those questions where I'm pretty sure the answer is obvious but getting it expensively wrong could maybe be avoided by asking an easy question here... :)

    I've got a 4x10 cabinet, and i've blown 1 speaker and 2 of the others look like they're on their way to speaker heaven too...

    I want to replace all of them with 4 new speakers that'll handle a bit more power, and like the look of Eminence Gamma 10's (8ohms/300w)

    My question is... if I wire them up in the normal 4x10 way... (2 x (2 speakers in series) wired in parallel) ---- would the total power handling of the speakers be a sum of each of the speaker's power rating (i.e. 4 x 300w = 1200w), or would it be something else?

    Yes. But if the speakers aren't properly matched to the cabinet it could sound really bad and they could blow rather easily. If the speakers' parameters suggest they're ok with the cab volume, then you can match them up by tuning the port (changing its length and cross section area).

    In the meantime, if you're using a cab in which one or more of the speakers is blown it'll screw up the tuning and make the others speakers more likely to blow.

    If you can post the measurements of the cab, we can check the speaker's compatibility for you. There's also a 99% likelyhood that w will have to readjust the porting...... trust me it'll be worth it. You're wasting money otherwise.
