Have you guys been following along?

I started with the measurements we most hear about in the market place.

Last week were the measurements that really matter.

This week, we looked at the most important tool used in the design stages. Check it out.

The second video is my favorite yet.  I thought I had an idea how to read impedance and spectral decay plots but it turns out that I was an idiot.

all of these are very interesting
But i have to agree video #2 was exceptional.

thanks

I agree and have a question: How do you read the spectral decay when a segment appears to dog-leg to the right crossing a number of frequencies?

I would also add the room room issue completely.

I just opened a thread in ASR forums / Speakers, Headphones and Room Acoustics. With four screenshots for now.
