This funny

Radrog, you're not making sense. You complain that the driver costs so little, but you won't buy them from the manufacturer because they costs so much. The speakers "cheap" components, yet you like the sound. And that seems to make you unhappy. Finally, you didn't even buy them from Krell, but you think Krell should give you the replacements free. I guess there's no pleasing some people.

Shadorne, pro drivers should be far more robust than the home audio versions. It's akin to a commercial lawn mower intended for use 8 hours a day five days a week versus a residential mower designed for 1or 2 hours once a week. In studio use a monitor has to deal with far more out and out abuse than a home oriented speaker would ever face.
