I had Ted Weber make me a special speaker many years ago. A 15 watt Blue Dog Ceramic with an EIGHTY OUNCE Ferrite magnet with a Neo helper. I asked him if I should go with a 30 watt since I run the amp wide open a LOT ! He said that the giant magnet would keep the voice coil from getting out of line. It's been 20 years.
