Hi all I have a full set of Celestion C series speakers including the C6 sub-woofer all being driven by a Denon A1SR amp. During films with heavy LFE the sub starts to smoke and smell after about an hour or so (had to stop Matrix Reloaded this evening to allow it to cool down - and hence now typing this). Can anyone give any advice as to why. Amp to beefy for speakers? Faulty sub? Wrong settings? etc. I have the sub conneceted into both the L&R inputs using a Monster 1 into 2 phono cable. Thanks. Apreciate any replies.
