Re: Can a tweed deluxe handle a band practice?
power handling is basically heat dissipation, the higher the power rating the more heat the speaker can dissipate. a 100w speaker dissipates heat better than a 30w speaker so it can take more power before it fails.
efficiency or sensitivity is unrelated to power handling. typically it is measured in dB at 1 meter with a one watt signal fed into the speaker. a higher (100db for example) rating means the speaker puts out more volume with the same power (1 w) than a lower rated speaker (96 db). so comparing a g12m greenback (97 db) to a g12h (100 db) the g12h will put out more volume with the same signal from the amp.
so in this case you have 12w of power, putting a more efficient or sensitive speaker will give you more volume. with a 12w amp i would shy away from using a 100w speaker since you wont be pushing it very hard and it might be sterile sounding. this is pure speculation on my part and dont let what i like tonally influence you too much, it could be just what you are looking for. as you said, even a 30w speaker probably wont break up much in this situation.
when kelsey says not to put much stock in comparing ratings between different manufacturers, there is some validity to that. the biggest discrepancy is in the 1 meter measurement. where are they measuring from? the dust cap of the speaker or the front of the baffle? that could be a couple inches difference which will definitly change things. having said that, its not like comparing apples to oranges, more like a granny smith to a yellow delicious. a 100 db jensen rating may not be the same as a 100 db jbl rating but you should get that both are loud speakers.

an effective speaker is surely essential for the amp.
