Ive just acquired a pair of FB1 speakers and must say Im impressed. They really do sound good. They are perhaps a little too small for my room, and Im going to look to audition a pair of their bigger brothers the Ob1 ... How uch of a step up are they from the FB1? The FB1 is very musical and is very good in areas of speed, dynamics, bass and most importantly , to me, a realistic sound. The bass is very clean and articulate, but mids are very good. They were quite bright with the brass jumpers in ( i only have single runs) so I swapped these for silver jumpers and they sounded great. just listened to Macca - all the best - and it sounded great! live and let die was spectacular...All in all a very good buy and significantly better than some of the more pricey dross Ive tried previously. If youre thinking of a pair 2nd hand - go for it! very good mid - priced speakers.
