The volume in both is the same difference in active or passive. Meaning, the 4 is still louder in passive as the 5 in passive, the 4 in active is the same amount louder than the 5.
Unamplified, they both sound like solid body electrics unplugged.
Hence the reason for the OP, they are basically the same, barring SSS and HSS, yet the 4 is a fair amount louder.
