Hello,
You may reconsider selling these speakers. I have discovered distortions caused by the ripple in the Bias supplies. I made a filter that is inserted between the Bias supply and the siaphragm – Plug and Play. The sound is now amazing. Dissonance, Imaging, Clarity, Focus, it keeps getting better. I posted a discussion on this forum. The price of my upgrade is $700.00 US.
