All were tested and found in good working order to Spec. With the "DATS V2" speaker testing hardware and software.
These are an American made Transducer and the Polypropylene used was of the highest, pure grade. I guess because of that and light wear? They have survived in their current shape. Not even the foam is worn out, "which can be replaced", and that is very rare. The only markings on the magnets look to be cast in serial numbers and also there are numbers that corresponded to the count in the cabinets on each magnet.
They are all twelve in the exact same shape as the one in the pictures. Individually boxed, Six speakers per case box. Each case box will weigh about 40lbs.
I also have the original 8 Emit tweeters If anyone is interested. And a full set of 12 Monsoon Magnetic Planar Transducers.That were to replace the original midrange drivers that seem impossible to get fixed or find original replacements for. Other parts "may" become available as time goes on. The item "Original Infinity RS-1b Parts.
