i like the psd 2002 as well, their prices are really good, some friends drop by to listen to my Pi 4 with my 1.5 watts amp they can't believe the bass they hear from my Pi 4 and the mid are really good as well but seemed to them that the Pi 4 are lack of high, generally it is enough for me.anyway the Pi 4 is the best speaker i had so far, i used to have speaker that cost USD 3000.00. and the cost of building my Pi 4 is only USD 600.00 with all those Zen & auri with bypass cap in the cross over.
i believe it is a matter of personal taste like you guy say and i will try doing something about the connection and the wireing
changing the compression driver is killing for the time being.
thanks.
