The R400 is a 2-way MTM design. No way it can be as good a center channel as the 3-way 703 or 706c

Perhaps the capacitors in power supply for the amplifier has to drain before it will stop hissing. Or, sure you are not missing a cat?

See you back on the other forum.

I am sure you will be happy with the 706. It is a fine speaker. Where I get on my soapbox is when people assume that one needs a horizontal center channel speaker because somehow that laws of physics…

BTW, I almost did not read your thread as I found your use of the first 2 words in you title to be very inappropriate.
