Hello all,

Sorry to introduce myself with a request for help! I have just acquired an RX-DT75 from eBay. It was £100 here in the UK - in visually perfect condition and good working order, with the original remote and manual. A bit of a bargain, I thought!

There is just one problem, as soon as I put the volume up to a loud-ish level on any music that has heavy bass there is unpleasant buzzing / rattling, which leads me to think the foam on the woofers is shot. From what little I have seen on YT, these woofers are a bit weird and this may be difficult to fix, but I wanted to tap the wisdom here as to how possible this is (or not), sources of parts etc, if anyone has experience?

I suppose I could return it, but I don't really want to, as I am sort of in love with it even with this fault!

Thanks very much for any thoughts.
