Depending on the version of the Khorus you have you could likely get replacement drivers, at least for the tweeters, at www.madisound.com . I have the Peregrine X Mark IIs (they use identical woofers to the later Khorus models). I plan on taking the woofers out to Madisound in the next month to see if they have replacement woofers. They already supplied me with exact replacement tweeters. My speakers are driven very lightly and have zero problems. I just got the extra drivers just in case because I plan on having my speakers for a long time. Great speakers !
