Did this really kill my monitor?

Knew I had some bad bass resonance issues in my room, and one monitor was
closer to a corner than the other, so did some basic level checking with
some tones & a level meter. 40Hz was a big problem, 50Hz less so. Was
trying the different EQ & placement curves on the monitors to even them
out - when the bass cone in one stopped working completely. Yes I was using
sine wavs, but only in short bursts (just long enough to get a reading ) and
not very loud (85-95dB SPL in my listening position). The overload
indicators were never on. Is this really likely to have done the bass
driver or its amp in? Mackie 824.

Certainly shouldn't have. Did you hear any signs of 'distress' before it failed
?

You've heard that phrase "stuff happens"?

So what's the warranty/spare parts situation like from your
perspective?

HR824s are definately fixing!

If you have to ask the question, you probably lack the
skills to do something about it.

Time to find someone who can...

The 824 has a lot of protection stuff in there, so it is hard to damage.
You may have blown a fuse, though, and it is worth checking before doing
anything else.

I wonder how good the Mackie doc is?

According to

http://www.mackie.com/pdf/hr824_om.pdf

There are no user-servicable fuses. The fuse that does exist
controls the whole enchelada. IOW, if you blow the fuse, no
light, and no sound from either driver.
