I have owned a pair of F's from early 70's till mid 80's till they blew, traded the drivers in on walsh 4's(recieving full credit towards the walsh 4's) kept them till last year when I traded them in on walsh 300's, again recieving full credit for these towards the new 300's. I personally feel that these are the best sounding yet. They are not as detailed as some other brands(tyler& silverline audio) but they deliver the best soundstage and imageing of any thing that I have yet heard. They do require lots of power to really sing (I curently use a bryston 4bst). Considering there trade in policy I only have paid for one set of speakers in 30 yrs.
