B&W 802 Nautilus speakers

The amps are new and wires the amps are new an the wires so you think it could be some type of short in the speakers?

Whenever you change things and problems appear, best to first suspect that whatever you changed is the issue. If your speakers were working fine with your old amp and wires, look there, new or not. Process of elimination - try your old amp, then your old wires with your old amp, etc. Also, recheck all connections.

All good advice above.  Assuming ampler is not the problem its probably a blown driver.   Check each driver with an Ohm meter and see if you have any out of spec.   

garryh16, I'm having great difficulty thinking there is a problem with the speaker in the scenario you describe. Can you verify the sound cuts out at low volume and not high volume? Also, would you mind listing the other components, amp, preamp, source?

Also, if you have headphone option, try to replicate the issue thru headphones instead of with the speakers. Cheers,
