The dealer I used to deal with in Toronto carries PSB XT2 & in there opinion the 800f's are a noticeable step up from the PSB's.I used to own the PSB 40mkII way back.So will see what the 700f's sound like they are true 3 ways like the M60's & the 800f's are(800f's have bigger woofers). So looks like either 800f's or M60 hp!!But will see Fri what I hear!!
