You are referring to the Pyramid MET 7.7, which is a terrific small monitor. I have owned two of the earlier incarnations of this speaker, and thought they were among the best small monitors I have ever heard. When the MET 7's first appeared, Richard Sequerra offered them as either a stand-alone unit, or as part of a larger, full-range system that included a bass module and a ribbon tweeter.
For more information about the Pyramid MET 7.7's, I suggest you go to Sequerra's web site at: http://www.sequerra.com/
There is also a good review of this speaker, done in May 1999, on the Planet HiFi site at: http://www.planethifi.com/planethifi6/may99met771.htm
