its samsung 1200w by 6(5 plus sub). i got it all 1 package. the rear speakers run wirelessly on it. all speakers are still in great shape but receiver might need to be replaced soon. i didnt want to replace the all speakers since they are still good. every receiver ive looked at has the sub using coaxial input on it and mine has 4 basic wire input. also the rears have a different connection to go into wireless device but i would be able to just use different wire and just run into the new receiver directly couldnt i? is there any receiver that would work? or would it be easier to just get another system all together? thing i dont like about the new all in 1 systems ive seen is that i cant find 4 tall boy speakers in the set. mine has the 4 which i like. if i got a new system, could i use my rear tall boys with the other speakers?
