"I own a JRC NRD545 DSP receiver which as always produced audio that I found really harsh to listen to on single sideband. On Saturday at the GQRP convention I purchased NES10-2 speaker on a recommendation from a friend. I have owned and still own many audio filters of one sort or another but your product was a revelation. The NES10-2 does exactly what it says on the tin and I can now enjoy listening to my receiver."
Best regards Ken
