I guess my countrymate that those purchases are actually quite typical. Though I don't use neither products but I guess that's very typical purchase what people does.
Apparently, according to ebay.
I expect it to be alot less then 350W but i don't really mind, was £3 for 4 of them and as long as they work then it's fine. Just need them to see if my little experiment will even work.
I did put ' around the 350 to show that i didn't think it was actually 350W
But i dont think size matters when it comes to speakers, my z5500 centre speaker is 69W and my guitar amp speaker which is about triple the size of it is only 25W
