I think they're unique - in terms of looks. Not ugly. Simply looking at the woofer cover tells us that we are not dealing with an ordinary speaker.
PMC speakers are great ! tonally accurate, detailed, and will tell you the truth about a recording without going overboard.
They are very popular in studios. Same with JBL horn speakers, TADs, and ATC speakers. That's because these speakers are marketed towards people in pro audio; and they actually fulfill that purpose.
So if anyone were to knock these brands for any reason; yet the music you're playing on your own system sounds great, you can safely assume that one or more of the above speakers from/brands were used in the final stages of post-production. Otherwise, lots of mastering errors and even mixing errors that were never corrected.
