Not strictly a measurement mic, but is an omnidirectional condenser with a very flat response.

Thank you, it looks good.

 

Behringer are great bang-for-buck.

The dedicated USB measurement mics with the ruler-flat response are about double that price.  Still pretty good value compared to what you had to pay for that type of thing a decade or two ago!  Just depends on your budget.

 

I use the Dayton EMM-6 measurement mic.  But I have a great little ART USB Pre-amp, so I didn't need the mic to have USB built-in.

So that Behringer will give me enough accuracy to tune some bookshelf speakers?

That is not an approriate choice at all.

Something like this microphone design is what you need.

 

Here is the USB version

...or the MiniDSP Umik is another option.

Hmm, the measurement microphones are a bit over my budget given the build is coming in only just over $350..  I don't think i'll end up building too many more speakers after this second set.

 

Will give it some thought.  Thanks for the replies.

The wrong type of microphone will give you data which isn't representative of the speaker .... you'll then design/optimise the speaker based on that data.... and your measurements will tell you "you've done a great job".....  but it won't be ;) 

 

You could sell the microphone once you're finished.

I expect most DIYers who have a USB measurement mic would have it sitting in a drawer gathering dust most of the time.

Might be worth putting your feelers out to see if another Sydneysider has one you can borrow.

thanks for the advice :)

I recently discovered that my Dayton Omnimic (it's pronounced Omni-mike) USB microphone works perfectly for Zoom meetings.

 

Now there's reason to get it out of the drawer at least 5 times a year!

 

Good selling point too, perhaps?
