DIY Bluetooth Speaker

This is my bluetooth speaker, It has a active crossover and it's bi-amped.

After this video I replaced the 3.3uF cap for a 25uF cap on each tweeter to widen the frequency range. Now tuning requires less PEQ adjustment in Room EQ Wizard and it sounds like it has a pair. I also upgraded the battery to a 5s4p setup to get the amps running at a higher watt rms rating, so now it's twenty LG MJ1 18650 batteries.
