Mockingbird Audio LSX Speaker System

This model is retired.  If you found yourself here on purpose, you should move along.  These are no long available, and probably will never be produced again.  As a reviewer, buyer, hobbyist, DIY’er, musician, etc.., I found this design, and another design by Danny using a similar arrangement, were some of the finest speakers made, at any price (really, at any price).  Unfortunately, the manufacturer of the BG drivers was purchased by corporate douchebags who demanded license agreements, upfront yearly fees for the privilege of using the drivers, and a percentage of the total sales (regardless of the percentage of the total cost attributed to the use of BG drivers in the system).  No other parts or driver supplier has ever made such moronic, imbecilic demands (this is the kind of thing that goes hand-in-hand with jet engines, supercomputers, automobiles etc.., but not specialty audio).  No longer available.  Bye!
