In a few weeks the backplates on the Sound Lab U-1PXs here will be upgraded to the new Consummate version which will be introduced at THE Show in Las Vegas. These will be the first pair until they become available in January. Pricing has not been set, but I will know soon.
The purpose of the new backplate design is to make the speakers a lot easier to drive by both tube and solid state amplifiers.
