JBL L19 crossover differences

[vrobec]

Hello all!

I have bought JBL L19 loudspeakers. The crossovers have different potmeters. You can see it on the attached the picture. Which one is the right one or there are builds with similar components in crossovers?

Thanks!

Hi,
for me it's just a batch of different suppliers but the same specs, I think one can read 8Ω on the left one, same as the right. Others seems similar, even if can't read the PETP cap value. While you are at it, will you upgrade it?
Very tempting, new L-Pad, new caps, bypassed.
