Contour and Focus share the same tweeter but Contours highs are better becuz customised on a higher level...Contours bass goes deeper...Contour is more laid back speaker...has more deeper and higher soundstage...Contour has more advanced cabinet...5.4 will demand even more powerful and rafined amps to get it right...Focus is great speaker for the money...but Contour is better...not by far but better...no matter how older design is...i owned Focus 380 few years ago...no matter which speaker you choose be sure to power them with powerful high current SS amps or they will not shine their potential and you gonna waste your money...also you need to put them in atleast middle sized room to breathe properly...if you have any other questions feel free to ask
