Never heard SFBs but always been curious about them. A radical design for sure and one I see no reason wouldn't work. Certainly shouldn't be boomy, what with no box! I suspect Gilbert Briggs knew what he was doing.
I wasn't specifically referring to them... Apparently they're not bad at all!
No it was more like Goodmans Magnum's and Magisters and other such things (they are just a couple that sprang to mind) that you couldn't give away for the last 40 years suddenly going for £250. I'll admit I've never heard them but hifi enthusiast friends of greater age than myself have described them as bloody awful.... and that was when they were new!
I wonder if the big Goodmans were that bad, Joe Akroyd was involved with them at one time.
They probably roll off a little early at the top due to the cone tweeter, but most of us here could not hear that anymore
Partly fashion, fads and trends; a few years ago you'd find Garrard 301/401 decks in a skip, now they are in serious demand.
I had Wharfedale Lintons as a teenager and remember them as being quite good, but recently picked up a pair of their little brother, Dentons, which were well reviewed at the time and they were awful!
But were they still working properly? There are many things that can go wrong with a speaker over timeI had Wharfedale Lintons as a teenager and remember them as being quite good, but recently picked up a pair of their little brother, Dentons, which were well reviewed at the time and they were awful!
I picked up an SFB3 a couple of months ago at the last NVCF http://www.nvcf.org.uk/. This one needs serious restoration. But all the basic parts are there. When I saw it it had no price on. So I started by asking the seller what he wanted for it. He said he didn't know what it was worth, so what was I prepared to offer ? Stalemate. Eventually I smiled and said "Well one of us has to go first". "Thirty-five quid" he said. "Done" I said. I could tell from the look on his face that he thought this hadn't gone well ...

I'll admit I've never heard them...
I think what happened to the Goodmans brand had a lot to do with that. Seeing the word on all sorts of rubbish from Hong Kong did not do resale values any good.
You can get away with lighter cabinets when the drivers are efficient, as many of these old speakers were and at least you don't get the "organ pipe" resonance towers are prone to
When you have a 80dB/W speaker due to the use of a heavy plastic cone, the motor is generating much greater forces on the cone to move it. This is in turn pushing much harder against the cabinet structureThere is no correlation that I'm aware of between efficiency of drivers and the need for cabinet bracing etc!

Remember that Goodmans were a mid price brand, cheaper than equivalent Tannoys, so something had to give
