Look at music?

[Lars Jackson]

A bit strange but when I started to look for all kinds of downloadable programs when it comes to loudspeakers. Not any program for calculating crossovers but sound measurement software!
What microphone do you say is the better one? Have to handle frequencies between 20Hz and 20KHz.

Thanx! Lars Jackson

The Behringer ECM-8000 is a popular measurement microphone for the hobbyist. Not sure it will hold up well for industrial use (depending on the scale of your loudspeaker venture), but for $60US, you will likely get your money's worth.

If you are looking for higher quality and durability, there are others here who can advise you.

Thank you Kurt! I will take this under consider. My plan is to keep it in the small scale at first. Try it out and see what an inrest it will make.
I'm in need of more gear hear. A frequency counter, oscilloscope and some sort of analyser. If there are some programs to download it would be grate! Have found some but they are not for free! Don't have a lot of money!
