Evening all. I'm after some advice please. I currently have an eltax symphony centre speaker, but we are redecorating at changing the TV, so I would like to slim down the centre speaker. I've been looking at sound bars purely for the aesthetics, I know these are active and require low level input, however I was thinking of purchasing a broken one and converting it to passive. I've been looking at the lg NB2020a its only 40w (20w sub and 20w speakers) however I was wondering how much of this was the built in amp over the speaker power. I have a Sony amp currently driving a set of Tannoy M3 cherrys at the front and another pair of eltax rears, although I've just purchased some wharfedale PPS-1s to replace the rears. Does anyone know if it possible? Thanks.
