i have a pair of infinity sm-255's for my fronts, and a pair of sm65's for my rears. infinity quit making the sm series a while back and i am stuck on trying to decide which center channel to go with now. i emailed infinity and they recommended the il36c, which is from the interlude series, and also costs over $350. my question is, what do you think would match my current sm series speakers better: the infinity interlude il25c (same as 36c, just smaller woofers, and price of only $250) or the infinity entra center (only $200, and has 4" woofers). if anyone knows about these types of speakers, your advice would be greatly appreciated. thanx!
