Now Selling Revision 1.0 EMIT Diaphragms!
Over the first 2 years we had great success, and sold 1000 of these parts saving hundreds of Vintage Infinity Speakers from the Landfill, or from being parted out.  A few users provided feedback which I compiled and some small incremental changes, and improvements were made to the product.  Mostly to the Terminals which were an off the shelf item... New custom made terminals are now mechanically identical to the original.  Some small changes were also made to the Voice coil, slightly improving sensitivity, and lowering the DC resistance to be closer to the original.  All revision 1.0 EMIT's will now have the P/N AVA191218.
