Hi, i have this home theatre kit hooked up via my sony amp to my PS3 and seem to have knackered the centre speaker by playing music too loudly through it. I cant find the same sony replacement speaker so need a recommendation for a centre speaker. It needs to be relatively cheap and of the same dimensions of the sony centre speaker as it sits just below my tv about 3 inches deep. It also needs to be silver. The sony centre speakers ive seen on the web are too big for my needs at the mo. Its only a temp measure as when i redecorate im upgrading everything which is why i want the cost to be low on this. Any ideas guys?
