I can also confirm that the tweeter response can become soft over time. Tweeters don't always blow and stop working completely, but will dramatically decrease their output. Following the advice of some other HHs, I recently swapped out the tweeters on my DSP6000s and decided to go with SEAS Excel Millennium tweeters. I have been very happy with them and it cost about half of what the stock tweeters would run from Meridian. If you're interested, you can search some of the threads from last year and earlier.
