I currently have B&W 303's and have been thinking of going to 602's. Since I use them for HT mainly would I really gain anything? My crossover is at 80Hz, although if I bought the 602's I think I may get an ICBM and cross them at 50Hz or something similar. If I kept my crossover at 80hz would it be an improvement? I'm hoping they image better and therefore make my speakers "disappear" more. Any thoughts? P.S. My dealer provides a FULL refund on the 303's for up to 1 year from purchase if I upgrade so I'm not out anything except the price difference between the speakers.
