First Measurement with REW/US-144/ECM8000

Hello Everyone!

First of all, I'd like to thank everyone, especially John M & Wayne & brucek.

I am not good at English. Please understand.

I have been reading almost 11 months in this forums and get a lot of good information.
I listen mostly hi-fi music (classic, jazz and blues/rock).
I get ECM8000, US-144 and some cables and them connected.

This is my first attempt to use REW.
It took a long time to understand.
I've used the ECM8000-CS cal file in this site and my US-144 soundcard cal file.

Please let me know what you think of this graph, especially if something looks wrong.

Thanks!

Welcome to the Forum, accuton!

Looks like you’ve mastered REW quite well. Your frequency response graphs look good, as does your waterfall. Looks like you have some very nice speakers in a well-dampened room.

Regards,
Wayne

Hi Wayne!

I sincerely appreciate your compliment and quick reply.

I'll ask one more thing.

I'd like to know what can I do to reduce the differences between the left and the right speaker's frequency response and to obtain more flat frequency response.

I look forward to your reply.

Best Regards,
Accuton140

It’s perfectly normal to have left/right differences if your room is not perfectly symmetrical, or if your speaker locations are not symmetrical in the room. If you don’t have symmetrical speaker placement in a symmetrical room, your only option is parametric equalization.

Wayne
