John Fuselier was an outstanding speaker designer and his speakers sounded wonderful. I had a pair of 3.3's which I loved, used them for over fifteen years before moving on. Time aligned and I believed he used a series crossover, they sounded great and gave me many years of listening pleasure.
The two speakers on the ends where the grill cloth extends down almost to the bottom and the top plate is inset within the grill cloth look exactly like my 3.3's. There were a couple of incarnations of the 3 series so they could be a 3.0 or a 3.3 and possibly a model after that (I believe he produced a 3.8 but my recollection is that they used a different cabinet). At any rate, if they are a 3.0 or 3.3 then definitely worth considering at that price. I'm not familiar with the two speakers in the middle where the grill cloth stops further up.
One thing to consider though is that these were made in the early to mid eighties and as such are close to forty years old, therefore the condition of the drivers may be suspect as with any older speaker. If you could possibly arrange for an audition to assure that they are functioning properly that would be ideal.
