My OTA antenna feeds into TV, Optical audio out from TV to a Denon x4000 - for channels that don't have a fully clean OTA signal the result is sometimes a pretty healthy pop through the speakers when it glitches - I always mute the stereo and go TV speakers when the signal acts up, but perhaps that happened one too many times...
Speakers have also been thrashed on by a clowder of cats for many years:
- the foam enclosure surround is long gone - they tore out the center dome on the now blown woofer (although it's been gone well over a year...) - Speaker plugs have been ripped out a number of times...
I originally picked these up locally (Austin area) for $300 back around 2004 and due to the current physical shape the right move here is probably to move on to something else even if it's another example of these...
I do like the idea of going with a 1a version since they were actually designed to be serviced so that is a solid option for sure
No matter what I do I will use a cover I can slip over the speakers to protect them when not in use unless I end up with a solution where I hang them from the ceiling out of reach of the ruckus.
