Hi Wiimer
Mhhhh .Don’t know, but the dancing bars in the Ultra and what you hear does not match. More. Is it useful to have 25 Hz? My B&W are 48 - 28.000 Hz.

The lower limit for the Topping analyser is 50Hz.



The lower limit for the Ultra is 25Hz.


Ultra displays lower frequency bands than Topping, so the height of the leftmost bar is lower than that of Topping.

I did not mention the bar delay.

Matters system to system. My sub plays flat down to 14Hz, so only adjustable Spectrum Analyzers reaching down to 10Hz are any use to me.
