Bonjour,

This might be a simple question to some of you but, on a pair of Penta 3, I just had the midrange refoamed and now I have a doubt on the wiring. On the 4 midrange speakers, the 2 middle ones are cross-wired, but I did not mark the wires properly and now on one - is connected to -, and the other + is connected to -. That just can't be right. Any advice would be appreciated, wiring diagram.

Regards,

It is correct. 2 sets in serie.

Look at the placement of the speakers in the diagram. The wiring looks odd, but it is the actual placement of the (mid)speaker.

So the upper one iin the diagram s actual the upper placed mid speaker and the bottom one in the diagram is the bottom mid speaker of the 4 mids in the penta.

Thanks Beobuddy but you missed the point of my question altogether. Should the two - be inter-connected or the + to the -, and then is it the bottom - to the upper + or else. Can you enlighten me on this?

Regards,

Alain-Olivier

Definitely check out the wiring diagram in the Service Manual to be certain - that's what I did. Perhaps my picture might help a little....although it's hard to trace the wires.

BTW, the speakers are wired in two sets: each set in series. That means they will be connected + to -. 

The inner set: Green goes to negative (opposite phase)

The outer set: Blue goes to positive

In series means connecting from one (+) to another (-). It is a bit confusing, but it is ther for a purpose.

The outher 2 are slightly different (backwards) placed and needed an extra coil/capacitor parallel.

Thanks guys, you're of great help, I can now connect them an enjoy the sound of the newly revamped midrange
