    Is it worth measuring and EQing my IEMs & Over-Ear headphones with REW?

    I have been thinking about measuring and EQing my Beyerdynamics DT 900 Pro X and ZiiGaat Nuo with REW. Does this translate to noticable real-world benefits?

    Hey! I'm trying to set the delay between the mains and the sub. I followed this guide, but I'm getting significant cancellations, same result when using the tool in the WiiM app. I don't have these one to show, but it was really bad. So I started increasing the delay on the mains by 2 ms and...

    Apologies if this is a newbie question that has been asnwered before - but if so, I couldn't find the answer either on this forum or elsewhere.

    How Does REW or audiotool Measure SPL Without Knowing the ADC Reference? (Dayton iMM-6C Calibration)

    Hi everyone, I'm new here. I’ve just bought a Dayton Audio iMM-6C USB-C calibrated measurement microphone and I have a question about how SPL (dB) is calculated. The calibration file of the microphone has in the first line 1000Hz -37.4 that i suppose it's the sensitivity at 1kHz. However, since...

    Can this be Improved in REW (Boombox+ACPWorkbench+Rew)

    I have a digital piano, but at the moment, I can only use it with headphones because my room has poor acoustics—particularly an issue at 130 Hz that coincides with the C3 note. Implementing acoustic treatment is not a viable option due to financial and space constraints. For this reason, I’ve...

    Question about EQing speakers above 500 Hz

    Hi everyone and happy holidays! I know people ask the question and there is some debate back and forth about EQ'ing/room correction over 500 Hz. From everything I have read (which likely isn't even scratching the surface), it seems like more people believe we shouldn't EQ above 500 Hz. Okay...

    Weird subwoofer volume issue on KEF LSX II LT for stereo/mono bass signals. What's happening?

    As you can see from the attached graphs, switching to L+R from L only changes main speakers' measured SPL but not subwoofer's on REW measurements. The subwoofer is SVS 3000 Micro, connected to my KEF LSX II LT via its subtout. I don't think this behavior is normal. Denon AVR-X3800H, which is...
