Aerial 10T Owners and Anyone that can help

Here is my deal and gear:

Gear:

Theta Casablanca
EAD TheaterVision CD/DVD
Citation 7.1's (3)
Aerial 10T's

Now, the deal:

I have the 7.1 bridged into 2 channels, 450 x 2 @8ohms, very high current, 70 amperes. My gain is set to 0 on the Theta and using Madonna cd for pushing limits or the gear.
First, at excruciatingly loud volumes, the music will start to cut in and out. When I turn it down, it is fine. So, I am thinking it is the amp. I finally switched amps, to a Marantz MA-24 (30WPC CLASS A) and the same thing happens.

Here is my GUESS (guess being the key word here):

The Aerial 10T's have some type of cut off from the power amps to prevent damage to the drivers. Is it possible too much juice or distortion? What would cause the speakers (assuming this is the culprit of shutdown) to do this?

Any help is greatly appreciated.

Thanks Rwwear -

What does it mean if the Marantz MA-24 is doing the same thing at close to the same levels? Larger amp?

You want to hear the 10t's sing? I've had all the so called big power hitter amps on mine, up to and including the Classe M-1000 monoblocks. What's there now?..........
Levinson 33H. Best I've heard, 33's would probably be even better, however the 33H were FAR superior to the Classe's 1000W at 8 ohm output. Remember, Levinson claims 150W at 8 ohm for 33H, IMHO, much more.

You said earlier that the Marantz was only 30 watts per channel and even though it is class A, it still hasn't enough power to play at full volume.

I made a mistake, at 4 ohms, it is 47WPC into Class "A".
I assume this means it is much higher into another class?
How does this work?

I cannot imagine why anyone would want to listen to Madonna at excrutiatingly loud volume, but to each his own. You are asking much more of your amps than they are able to deliver. The amps when clipping are producing a square wave, which the amps can live with, but you run the risk of blowing one or more of your 10T's drivers. No, there is no such circuit in the Aerials that would cause such a sound, just the sound of the amps clipping. The 10Ts are capable of very loud and dynamic volume if you want to do that to your ears, but you need to consider much better amps. Big Classe amps bridged mono would serve you well at a reasonable price. Take care of your ears though. Those you cannot replace!
