3-Way Crossover Design - DIY 3-Way Hi-Vi Tower Speaker

I designed simply what best fit the drivers' capabilities while focusing on keeping the woofer in doing its job handling the bass, the mids handling the full midrange and so on. 500Hz and 4000Hz were chosen as the crossover frequencies. An L-pad circuit I felt was essential in keeping the response of the speaker perfect as possible. I didn't want anything to stick out. A schematic of the Hi-Vi 3 way crossover design is shown below.
