If the problem is indeed the microphone, you should easily be able play a sweep or a test tone, and not be able to hear this audible 10dB drop as you pass from frequencies below, at, and above your problem frequency. Especially since you say mic position doesn't matter, your ear position shouldn't matter either.

Smiley face was of course hyperbole bur not to far off. From what it sounds like there might be an exciter in there as well to give that sparkle sound. Whatever - the nature of the device is contradictory to the concept of EQing a speaker flat. You won't find anyone here with this on the master outs of there rig.

Thanks David.  That is a good idea.  I actually have another decibal meter that I could use along with a test tone to determine if it shows the same type of db drop.  This would help to confirm whether or not it is indeed a faulty measurement mic.

Is this "problem" something you are hearing, or just seeing on an RTA?

No - Not really hearing anything that stands out.

It hasn't really been talked about as much as I expected but an RTA has very limited usefulness for measurement. Especially indoors. I would just move on. The RTA is not the right tool for fine tuning in the room to get the last little bit of improvement.

No your quite right, an RTA doesn't give any time or phase info, and thats whats really needed here, and would allow us to find out if the problem is because of the crossover.

However the problem is that with it being a passive crossover, even if the user had something more comprehensive to measure with, it would be slightly academic and it wouldn't matter much as he cant do a whole lot with that information. His only choice is to swap polarity on the HF and see if it makes it better, which has been suggested. If it does great, if not then switch it back to the way it was before and unfortunately it'll just have to be lived with.

But yes your quite right, a measurement with a more sophisticated tool would give us more information to work with.

But we all know that for many people, it's how it looks, not how it sounds..........

I am seeing the same thing in a different pair of speakers from the same manufacturer. I saved the traces and can post them if interested.(don't really want to hijack the thread)
