    Excess group delay?

    Here are two images to show things more clearly. The only difference is the amount of delay being added to my mains. My interpretation is A) I've gone in the right direction and B) I've fixed about 50% of the bass EGD. Would love comments, especially on the spikes above my XO frequency...

    Excess group delay?

    Hi all, a couple questions about the attached sweep. I want to make sure I navigated the menus right so my first question is simple, does this look like a proper display of EGD? Second, your opinion please of the measurement itself - is it considered to be good or bad overall? I'm just diving...

    Using the EQ function: proper approach for flattening mains?

    I'm getting close to having the system I will live with forever. At least I think so ":^) Across their (very small) production run, the 2SW-1 crossover was varied between 70 to 100Hz. I've experimented between 55Hz & 100Hz and always came back to 80. Going lower than 80 got me increased THD...

    Using the EQ function: proper approach for flattening mains?

    Apologies, I don't visit this forum often. Here's my kit. Electronics are miniDSP: An SHD and also a Flex Eight SHD output is configured 2.1 with an 80Hz 4th order XO The 2.0 goes direct to my (amplified) speakers The 0.1 feeds all bass to the Flex Eight, which in turn feeds all ten subs (I...

    Using the EQ function: proper approach for flattening mains?

    Appreciate your input, thanks. I'm trying to figure out "rules of thumb" here - the processes and procedures that are independent of the hardware you own. That's why I asked it the way I did. But to answer the questions, my mains have a low frequency power bandwidth (-3dB point when crazy...

    Using the EQ function: proper approach for flattening mains?

    I have fullrange mains that I cross over at 80Hz to subs. I also use the EQ function in REW to flatten the mains. Here's the question: In such an application should you let the EQ function process a fullrange sweep or a sweep that includes the 80Hz crossover? Many thanks.

    Weird interaction between REW and Qobuz?

    (This is a Win11 laptop btw) If I am streaming Qobuz and open REW, it always pauses the stream. No big deal, I just go to the Qobuz app and toggle the play button twice. The music returns but I swear it sounds different! Please tell me I'm crazy and this is impossible, but I've repeated this...

    A question on the EQ function

    Should "target level" (see pic) be set the same for left & right channels? Thanks.

    Acoustic measurements near the rooms' noise floor?

    Correct, I just muted the output to make noise measurements. I won't do that any more and I appreciate the clarification!

    Acoustic measurements near the rooms' noise floor?

    Please see the attached mdat. Question: How does REW behave at, and below, the rooms noise floor? At some point those two curves cross - is that the magic frequency I should limit my LF corrections to? Many thanks.

    Critique my mdat file?

    I'm asking for folks to look over my shoulder here. What does this mdat file say about my speakers? What does this mdat file say about my room? Many thanks...

    What is wrong with my computer, sudden change to REW sweeps no headroom, high distortion or is it REW issue?

    I had the same symptom, it must've been a Windows update that changed my mic level to 100% because I sure didn't adjust it?? Lowering to 32% as per John solved my problem.

    Distortion graphs display but numbers do not

    Please see picture, I have no problem getting graphs but I can't find the way to get numbers to display at the bottom. What am I missing? Thanks.

    Optimizing the EQ function

    Oops hit send too soon. I am using the "EQ" function on my main speakers and I have two questions on the basic setup for a stereo pair: 1) Should I process left main & right main separately, or process the average between them? 2) How about weighting? Any notes on that? Surely there's a...
