A colleague posted a pic of a speaker on another forum and nobody seems to know what it might be.
I hereby implore the knowledgeable members of this august group to dive in and offer up some hope!

........a bad design to me. The tweeter and mid frequency response HAD to be affected by the directly below top of each cabinet. Talk about frequency bounce and scatter.Plus the midrange to woofer offset looks really excessive if they were trying for aligning acoustic centers.Prob an early to mid 80's design using the engineer's "ears" as the measuring microphone lol

  Some designs tried to (and failed) to compensate for group delay (crossover phase shift induced time delays) by offsetting drivers beyond that required for time alignment. This, of course, does not work since phase roll associated with higher order crossovers essentially MEANS non-constant group delay, aka the group delay is frequency dependent.
  
  If the group delay was not frequency dependent the laws of the universe would be different and speaker design would be a whole lot easier.
  
  Speculating on the design with nothing other than appearance, though, it pointless. For all we know they could employ special active or digital crossovers.
  
  Cheers,
  Presto

I wonder if Sequerra had something to do with these?

It looks much like the Met7 above the Sequerra subwoofer.

The cabinets are non-standard so they maybe a clone, perhaps?

  One of the guys on the other forum suggested that perhaps they might be an early Elipson design.
