Will a 75 watt speaker with a 60 watt amp be okay?

I Have heard of people saying you need to get a speaker with at least 150% of the wattage of the amp. Is this true? I play mostly high gain metal and hardcore. I am going to want to use this amp it gigs as well where I will be playing 30 minute sets with not much time in between songs

I'm no expert but my limited understanding is that, if the speaker has a higher wattage rating than the amp, you're fine. If the amp was 75w and the speaker was 60w, then you'd be in trouble.

Yes, you're fine. As long as the speaker is rated for at least the output of the amp you're OK.

In this context you'll be fine. If you were pushing the amp into power section overdrive, not so much. Playing high gain I assume you aren't doing that, though.

what amp are you talking about specifically? If it's a SS amp then you're fine, a tube and you may want to be careful of power tube overdrive, which could push you over.

As long as you don't crank the amp you should be fine. Should be safe turning.g it up to 5 or 6. More than that and I'd get wary.

It depends on how the speaker was rated. If that's a continuous RMS rating you'll be fine, since peak power handling will be significantly greater.

If that's the peak rating, it's almost certainly not sufficient for a 60w tube amp, since a tube amp will put out considerably more than the 'rated' power when driven hard.

what's the amp and what's the speaker?

considering you're playing high gain you're probably not pushing the power amp too much so it'll probably be ok, but it'd still be worth knowing what amp and speaker you're actually talking about. different speaker companies rate their speakers differently.

I wouldn't worry, I'm sure the 75W power rating on your speaker is being conservative.

I have a 60w speaker in my 50w amp, and I've never had any problems.

probably ok, though don't quote me on it. celestions normally have the rep of being pretty conservatively rated. Maybe email celestion to see. if they say it's ok, and it's not, then you could complain. as opposed to "some random dude on teh internetz told me it'd be ok"

It really will be fine. Just keep in mind that anytime you have the amp up full blast (probably never, but who knows) you are actually going over 60 watts. Speaker companies know about this though, and I believe their ratings are extremely conservative because of it... But I guess we can't always assume it.

Just don't crank it all the way and you're fine. Literally anything below full blast should be OK.

With that combination you're fine, the speaker in question is rated at 75w rms, so peak power handling is significantly higher. Crank it and don't worry.

I've seen 150 watt speakers in 20 watt amps.

Speakers are, as far as I know, often rated for what kind of input they can handle. They don't "need" a specific power input.
On top of that, different speaker companies use different standards. As far as I know, Celestion rates their speakers a little higher than the amps they were designed for - a 60 watt Celestion will work perfectly with a 50 watt head (experience talking - Celestion Vintage in Peavey Valveking), though you may want to be a bit careful with a 60 watt amp such as a 6505.
With a rating of 75 watts on your G12T, my guess is it's actually designed to be able to take a 60 watt amp's peak output. Maybe not crank it up as far as it'll go, but you should be fine at sane levels.

You may get some speaker distortion with it that close.

with el cheapo speakers and your amp maxed, i might be worried, but qualitys speakers are generally over rated.

thats why ac30s have an option to have a 30 watt, 2 alnico blue option. thats a direct match, and ac 30 were made to be cranked.

i run 40 watts into 60 watts of WGS speaker - i am not worried in the least. i have quite a bit if confidence in the quality and USA make of WGS speakers. i hope i do. im probably never going to overdrive 40 watts anyways.
