Line Magnetic Field Coil Speakers

They look well tasty Geoff, not ruinously expensive either. Lot of money to take a punt on though, you know anyone who’s heard them?

Thanks, been googling, seems there’s little in it between them.

Bet me  wee falcons would kick they're arse.........David and Goliath anyone.

😁😁😁

Considering the size, the dollar price isn’t as high as I’d have expected. My only beef is the grilles. Probably the ugliest ones I’ve seen on any modern speaker. I’d love to hear them.

There's always lots of claims made for field coil speakers but we seldom see any real world measurements of them beyond gross sensitivity, which is often their strong point. I don't know much about them, do they tend to be more linear than magnet based cone drivers? One assumes much less thermal compression as the power into the voice coil can be much less and the magnet is now a fixed coil so can be made accordingly beefy as it doesn't affect moving mass.

Have you ever heard a well set up Klipschorn in the right room, I would hazard a guess they got it right back then.
There is a nostalgia wave on at the moment, and for the most part you are correct, most of the overrated old stuff certainty sounds like it is playing through your cardigan. 

Guess I am to old for modern Bling things.

They did get some things right back then which is why it is such a good marketing tool. You've only got to look at the number of people who end up with Tannoys, QUAD electrostatics or, as you say, Klipshhorns, after years of trying all sorts of speakers to know that is true. But it doesn't extend to everything old.


One thing about the old speakers that are still rated today is that they were all pretty large. The biggest lie ever sold to anyone was that there is some inherent advantage in small speakers (they're 'faster', they 'image better', they have 'tight bass'). All total hogwash. All small speakers are inherently compromised. But they are cheap to make and to ship, even if that isn't reflected in the sticker price.


If you look at that review the things he likes about the speakers are the scale and the effortlessness. Both are functions of their size, nothing else. The things he doesn't like - the lack of air in the top end, the limited bass extension, the lack of resolution of detail, are all characteristics of a single driver speaker.

One of the lads at a previous Owston brought a set of OB’s he’d built with a pair of 70 year old German field coils- might have been Klangfilm but I’m not sure. They sounded amazing, still probably the best I’ve heard a cone speaker sound.

That's only if you don't count all the lies about hi-fi...

Only the mid/top is horn loaded in the TAD 2401 though. 600Hz and up. I've no problem with that, it's single driver horns or bass horns that I can't be doing with. I know some people like them, but they never sound right to me. 


Most multi-way speakers I have heard/owned I have liked. Never had the problem of hearing the individual drivers but then I don't listen near field like a lot of people seem to do. Another myth is that single-way or two way speakers must be intrinsically better because they are simpler. Usually propagated by people who have no idea how a loudspeaker works.
