Hi,

Today I have used for the first time Room EQ Wizard with my mic behringer ecm8000 to measure my old DIY speakers.

All drivers was measured at only 2 cm from mic.

After these measure I got confirmation that the crossover need an upgrade.

First is clear that the woofer is not 90 dB like the midrange and the tweeter (as usually happens).

There is a strange unstability at 170/200 Hz that happen only if the woofer is inside the box, but is not clear the cause.

The measurements are very different from the simulation (2010) like I expeced but I don't sure how I can interpret these differences.

I have simulated a possible update crossover with more flat frequency response.

Any suggests ??

Thank you !!
