I’ve owned both Joseph, audio speakers and Harbeth.
I’ve got a good bead on their sonic qualities.
(You might also look up Herb Reichart’s review of the Joseph pulsars’s
As he compares them to the Harbeth monitor and he nails the essential difference
1. Look up the audiogon thread comparing the Harbeth SuperHL5plus
speakers versus the Joseph audio perspective speakers. In that thread, I do an extensive Comparison between the Harbeth sound qualities and what you get with Joseph. Pretty much everything I say there applies to the basic differences between the Harbeth 30/pulsar.
2. Don’t worry about driver corrosion. I’ve never seen any
Joseph audio owner report it. Bit more to the point:
Joseph audio updated their drivers quite a while ago
To The Graphene coated versions. The main point of
the graphene coating Is that it stops corrosion. (Which is only an issue in certain climates anyway).
