Make Bi-Amplifier LM3886 For Active Studio Monitor Speaker - PCBWAY

Order pcb from pcbway https://www.pcbway.com/
This is my DIY try to build bi-amplifier system using LM3886 gainclone IC for the final amplifier stage.
I design this project with simple components that easy found on market.
The way this amplifier working is when mono signal (Balanced / Unbalance ) give to the TRS input or XLR input, the signal will be divided by two way active cross over system with cross over point at 2KHz. The signal separated by two way :
-Low freq processed by lowpass filter and will be amplified by LM3886 final stage amplifier U3 and delivered to woofer speaker
-High freq processed by highpass filter and will be amplified by the next LM3886 final stage amplifier U2 and delivered to tweeter speaker
Both of them will work and produce sound that matches with the character of the speaker at the same time. To make stereo you need to build 2x of this circuit.
This circuit need 24V-0-24V /3-5Ampere transformer / mono.
So, what does it sounds like? please check the video.
