If you compare the LR4 and LR2 frequency response graphs, there should be no pit or amplitude decrease on the LR2 graph. This will mean that both settings work well.

It is impossible to achieve the perfect Step Response in the real world. It seems to me so. There are always compromises. Something turns out very well, something is not very good, but acceptable. Sometimes you think that there is a way to get what was acceptable is very good. To spend some time...

Could you show on the graphs what causes your dissatisfaction when applying the available filters in the range of low-midrange and mid-high crossovers?

Does your equipment have the ability to set delays for individual channels? For a mid-range driver, for a high-frequency driver?

Does it work automatically with every measurement? Or should it be included somewhere?

John Mulcahy Does room sim have a switch for positioning speakers along the short/long side?

No. I measured the wire resistance of 0.075 ohms with REW without additional resistors. Rsense 34 Ohm.

The measurements are almost the same. There are no obvious signs of defects of one of them. They both have a problem with HF. You must listen. If you don't like something in their sound, to understand. Measurements can show something, but may not show any problems.

BL and MMS almost coincide with factory parameters. What can affect the mismatch of other parameters is an inaccurate measurement of added masses (you need accurate scales with two signs after comma), too high measurement voltage (the dotted lines of the model on the peaks of impedances do not...

You must meet all the measurement conditions that the manufacturer had in order to get the same results. You won"t even be able to know about it. But it is possible to get similar results. For example, if the manufacturer has Qts 0.33, you can get 0.39, or 0.42. Try changing the sensitive...

In my screenshot, your measurement of the Y-519I-R was delayed by 6 ms regarding your measurement X-R. At your screenshot, all measurements at one time point. If all 4 measurements are Main+Sub, then nothing can be appreciated. There must be separate Main and Sub measurements to understand what...

It is not visible. All 4 graphs seem to be the same in delay.

TFL can be moved to the right by 3.5 cm, and C to the left by 3.5 cm. If the delays do not allow the speaker to be repositioned by a very small distance, it is possible to physically move the speaker. The peak of the sub"s impuls will be slightly shifted from the rest. It seems that on your...

I looked. For L, R, you need to install a delay of 4.83 m, or 15 ft 10.2 In. As for the side and rear, we will look at them later. At the same time, there is a small problem on the 35-60 Herz section, so it’s better to try 3 or 4 order of the filters. At a frequency of 75 Hz. This is the average...

I did not quite understand. You should work for some time in REW, each time listening to what happened. If the final result does not suit you, publish the MDAT file with measurements with acoustic synchronization of all your speakers. I will see which delays are better suited.
