How many would I have to kill to get new cones for Technics AB-S52 speakers?

Question

The cones(actual cones) are busted. I'm not going to be my usual smart-aleck self, and say the product got discontinued after 18 months. Oh,
wait I just did. I am a stereo dinosaur, even though
I had Rex Stores eliminated from my local economy. I used lobby-embargo-business-idiot castration techniques.'''

Answer 1

Most companies have electronic replacement parts for at least 3 years and some ones (like Sony) probably for 5.
Even though the product is discontinued (very common practice in electronics) , you should be able to call Technics support and get parts.
So, save your anger and give the friendly support people a call!
