Oui, mais ça n'a aucune importance. Vu qu'il n'y a qu'un HP dans le champ.
Du site Weber :
"In a single speaker installation, polarity means nothing. You may
connect the speaker terminals to the wires from the amp either
way. You may hear people talk about absolute polarity or
some other term used to describe the effort of knowing and
maintaining a specific phase or polarity relationship from the
pickup on the guitar, through the amp, and to the speaker. What
this means is that it is important to them that when they, say,
stroke down on the strings, the speaker moves out initially
rather than in. Some feel this specific phasing is critical to
their tone."
