Will an Ampeg PF500 blow out an Acoustic 410?

The PF-500 is only 500 watts at 4 ohms- 350 watts otherwise. Is the 410 a 4 or 8 ohm cabinet?

 

PF500 is only 350 watts with an 8 ohm cab IIRC. Since if you divide the advertised cab rating in half for bass. The cab can handle 300 watts rms of the 350 the amp could send it if needed. Sound relitively "safe".

 

You would be safe.

 

Correct, only 350 would go to one 8 ohm cab. You could get another identical cab and they would split the 500- or you can get a 4 ohm cab and that one cab would get the full 500 watts.

 

You don't need a 4 ohm cab. The amp will be perfectly happy and run cooler with an 8 ohm cab. IF you find you need more volume later add a second 8 ohm cab. More speakers get you more volume a lot faster than power alone. It will take a lot more than 150 watts (from 8 ohm load to 4 ohm load) to hear a real difference.

 

You can blow almost anything with almost anything! Really.

 

This.

 

Can't blow out an 810e with a B-15N head. I've tried

The thing to do in these situations is use common sense and your ears. If your cab sounds like it'll explode, it will.

 

You could but you could only use one 410hlf. The likelihood of you blowing a 410hlf with a PF500, though, is low.

 

What Jim C said basically you can blow almost any speaker with just about any amp. Not a tech here but when amps clip they can take out most any speaker even if it's rated for much more watts than the amp. As previously stated use your ears if you still have any haha evidently I don't as I have blown many a speaker!

 

All in all, keep in mind to check that 410 before it comes home.
I have, hands down, seen more Acoustics with a blown speaker than any others.
I attribute that to people not asking the questions you have, injuring the cab, then returning it.

 

Knowing how to use the gain and volume on your amp will save your cab.

 

Don't worry about wattage so much. As others have said just use common sense. Just make sure the resistance (ohms) is at a safe level for the amp to operate.

You can easily pair up a 3000w amp with a 200w cab and the cab would be fine as long as you:
Don't go nuts with volume
Don't go nuts with gain
Don't go nuts boosting lower frequencies

Use your ears. If it sounds like you're doing something bad you probably are.

 

Not a bad rig to have but if you could get an Ampeg cab with the pf 500 you could be set, and have very reliable good sounding rig that will handle just about every situation

 

Rate, the watts don't have to match. In fact, the watts cited for any speaker cab mean very little for buying purposes. That head (which is an excellent one, by the way) is made to power either 8 ohm or 4 ohm cabinets. The head will do well powering either one 8 ohm, two 8 ohm or ONE 4 ohm cabinet. Don't sweat the watts!

Now, this combo will play pretty loud. For many players, this will be loud enough. If it was me, I'd buy it and try it and see how it did. If you want more volume, using a 4 ohm 410 cab instead of the 8 ohm would not get you much more noise. Yes, you would get "all" the watts from your amp, but it wouldn't be a lot louder. Getting a second 8 ohm 410 would double the number of your speakers and that would be plenty loud.

Finally, when you're setting up a new amp/cab for the first time, start playing at a moderate volume and gradually turn it up. When what you hear is the same sounds getting louder and louder, that's good. If it starts to sound a lot different, be careful! Also, start with clean sound and add effects gradually, one at a time. As has been said, nearly any head can damage nearly any cab, especially if it's clipping. The best protection is to listen to what's coming out of the cab.

However, this amp and cab should be able to play really loud without damage.
