...that guy thought of classic JBL and Tannoy speakers.
The ones whose cones move inward when faced with a positive voltage.
Both Tannoy and JBL claimed at the time that their drivers were designed that way to preserve absolute polarity.
Follow Ups:
I once confirmed the JBL drivers move inward with a positive electrical potential. However, don't think there was a standard for that.
with in polarity voltage.

I don't think signal polarity was actually a specification in recording or mastering.
No but IIRC IEC defined it as such.
Older JBL's including the L series were wired inverted. As part of the HK empire, newer JBLS are supposedly wired correctly. IIRC James B Lansing thought the speaker should replicate the motion of the air hitting the tympanic membrane i.e. moving inwards, for some odd reason.
AKG headphones also a part of the Harman empire is still built polarity inverted. According to their literature: that is part and parcel of the AKG "sound"
