If you want more, take measurements separately for the right side (reference is also right), separately for the left (reference is right), separately for the sub (reference is right). After that, show (upload). To try to reduce the hole after 50 hertz, you can change the slope of the subwoofer...

Hello. I tried using measurements 1 and 2 to get a good total. Try delaying L+R by 8.26 ms, invert the sub (relative to measurement 2), and add +6 dB to it. I expanded the names of the measurements to make it clear what has changed in them. Addition of sub and L+R in the 8th measurement. L+R...

If you do the first one first, and then the second one, then after that you don’t have to invent anything, but just listen to the music. If timing the drivers isn't of much value to you, you might want to connect a passive crossover to the drivers and do some EQ work. That's it. Why is driver...

I have windows 10, I have a slider. REW v5.40 beta 112.

Fine. And not good. None of these measurements can be used to move towards your goal. Do not click 'estimated IR delay'. Where are the measurements for each driver separately? Measurements must have a full frequency range, from 0 Hz to 24 kHz. If you don't want to give the tweeter full range...

Then you should make your listening position in this place. Drivers aligned at the 1m point will not be aligned at the 2.5m point, much less the 4m point. The microphone, to achieve your goal, must be in the center of the listening position. Yes. Take 3 measurements with acoustic...

To time-match the drivers, you need to take multiple acoustically synchronized measurements. One driver is involved in one measurement, the rest are disabled. the reference driver could be the other side's speaker tweeter. Or a separate tweeter. You need to measure the tweeter, mid, woofer, sub...

I have always believed (and I think many others) that if the control for displaying this information is in the SPL & Phase tab, then this information is derived from a measurement. Thanks for the clarification. Maybe it’s worth transferring the control over the display of this information to...

John, hi. REW can display modal frequencies in the SPL & Phase tab. In this case, several levels of amplitude of modal frequencies are visible. Can REW generate data for the Room sim tab based on full frequency range measurements?

In part, the Bl/Mms ratio can be considered important when choosing drivers. But there are many other things that are equally important. Fast driver, that's good. But will he reliably reproduce what he was assigned? So you need a balance between both.

It's not clear how this works. Could you show a photo?

That is, the left tweeter is controlled by one channel of the amplifier, the left midbass is controlled by the second channel. The same is true for the right channel. Right?

Hi. Are the tweeter and midbass connected to different amplifiers when using a DSP?

Sound card calibration data is used if you will be measuring anything using a loop, an output-input cable. If not, you can not do it or do it later. To match the main speakers to the subs, you need to learn how to make measurements with acoustic time reference. Read about this in the help...

Sonarworks is a good microphone. Use a 0-degree correction file when positioning the microphone parallel to the floor, in the direction of the driver being measured. 90 degrees when the microphone is positioned vertically.
