Hello all. In my home cinema setup i have the denon 2310 av receiver, b&w cm5's at the front, b&w 686 speakers at the back and a dynaudio exite x22 centre speaker. what i'd appreciate an answer for is the following. Is my denon amplifier powering my dynaudio x22 centre speaker proply. As sometimes the sound seems to go slighty lower for a few seconds. or is it that my other speakers have bigger drive units and it falls short some how.In the denon manual it states 135w at 6ohms, my dynaudio speaker is 150w at 4ohms
