Hooked them up to a pa amp hitting them with around 650 watts per side- the first time I was actually able to hear and see the woofers moving. When fed power they sound AWESOME!

They came alive! If they were in a smaller room- no doubt they would sound incredible, the room they are in is close to 60 feet long and they sounded great in there.

The speakers also seem to have a 750 watt rating, which I am still around but not quite reached.

If you were actually sending them a true 650 watts they'd probably burn out in a second, regardless of what the power handling spec says (and you'd have a huge amount of distortion, known as clipping before they did. If you've ever heard some idiot with their car stereo really loud, and it sounds really awful because it's distorted, you're most likely hearing clipping, which is what happens when the amp tried to make more power than it's capable of). You could be peaking at 650 watts, but your average power output is significantly less than that (chances are it's not even peaking that high, though). If your amp has power meters, watch them and see how much power it's actually putting out. If it doesn't, you'll just have to take my word for it.
Also, there is no audible difference between 650 and 750 watts, all else being equal. This has to do with the logarithmic nature of the dB scale.

All I know is - I had them hooked up to a 400 watts per channel amp, hooked them up to one that is rated at 650 watts per channel- a preamp in line keeps the volume no more than half power, when turned to half power those woofers started actually moving and sound full compared to before.

With 400 watt amp running them, you could never see the woofers moving or ever really hear them at all. The tweeters were always audible.
Due to the nature of sound you would need a 4000 watt amp to double the volume of a 400 watt amp at plus 10 db. Doubling the wattage to 800 would equal to a mediocre only slightly more audible 3 decibel increase. I think your 400 watt amp is just not putting out the wattage it claims to.

Never said it doubled anything- I am saying a higher power amp made them sound awesome. I was pleased. But… jeez.
My point was simply that 400 vs 650 watts is kind of a miniscule difference. The quality of the amp vs the quantity is most probably what made the actual difference.
Maybe you could mention what amps you used.
Was the audio chain the same otherwise?

Nothing changed but switching speaker wire from one amp in the chain to another amp- both Qsc amps. A QSC Rmx2450 and a Qsc plx1804.

With one amp, the woofers were not able to really be heard or seen moving at all. With the second amp- not only could I see them moving really good- I could hear bass that I had not heard at all from the speakers. However - whatever type of magic you choose to “call it”, I simply see more power to them actually woke them up. That’s all I was posting for- if anyone else has a pair and may be unhappy with sound- add more power and see what happens.
If you ever switch back I'd love to know if you still hear the same difference.

Seeing as the higher power amp had been powering my two Cerwin vega folded horn subs, when they were using the lower power amp, they could barely be heard- so I did switch back to the original amps for the speakers. The carvers are the same as they were now- the tweeters can be heard but nothing really from the woofers.

How can I show you woofers breathing in a photo?

Miss my Carver Amazing's every day.
BE CAREFUL with that volume, those ribbons do not like clipping and are not easily repaired/replaced.
They do need a good high current amp to shine, I powered mine with a Carver TFM-55 and was a happy camper till someone offered me ridiculous money for the setup.

They are the prettiest things.
Had Carver electronics which I liked. Never heard the Amazings tho.
As mentioned by another, those ribbons are fragile and are extremely easy to cook. I've seen it happen and it's not pretty.
