Indeed, I am sorry that our periodic changes in performance data at Eminence lend to occassional confusion. This is certainly not ever our intention.

Most manufacturers feel comfortable publishing the same data for years and years without ever considering that changes in components, vendors, and manufacturering techniques have changed the performance of a particular item.

In this case, we just did a complete review of all our published data and power handling capabilities for the reasons I listed above. In addition, we knew that there were some anomolies in our curves caused by our anechoic chamber that needed correction as well as some significant improvements in our voice coil manufacturing techniques that would result in improved power handling. The spec sheets that we put in the products were updated about a month ago, our website with the new data was uploaded yesterday, and our new catalog will be distributed sometime in October.

As you can imagine, the logistics of informing thousands of customers about such changes can be difficult.

I apologize for any inconvenience this may have caused you.

Please contact me directly at chris.rose@eminence.com if you have any further questions or concerns.

Best regards,
Chris Rose
