Don't mind the LS50 look, but I can appreciate the problem posed by youngsters.
The Kyte OTOH, just looks fugly. I've read several reviews that praise the sound but give a thumbs down to the aesthetic.
I don't mind their look at all
You could buy a little loudspeaker foam of ebay. They come in different sheet sizes. Cut to size and use small velcro dots.
Unless you are a dabhand with a modelling knife... if you go this way I would suggest cutting with one of those 'zig zag' dress maker scissors.
Thanks for all comments, would have hoped for something "fit and forget"
I even tried my RX3 mid driver grill on Kyte but no luck.
Hmmm may I ask where you sourced those?
