The Bad: My wife has a cat (notice, I said my wife) so I took my grills off my B&W 603s. My four year old daughter recently pushed in (dimpled) all my 1" tweeters. Had I had the grills on, she probably would have never been attracted to the "shiny silver button-like domes". The Good: I called my local B&W dealer and I just need to provide my serial numbers and they will order and install replacement B&W tweeters FREE OF CHARGE. The Ugly (Question): To prevent damage from future kiddie curiosities I want to put my grills back on. Is there something I can spray on my speaker grills to keep my wife's cat away? Before you mention it, I already crank my HT when the cat attempts to use my floor standings as scratching posts. Which is probably why my wife is wondering why the cat doesn't respond to it's name anymore. Thank you in advance for your response. PETA activists need not respond.
