| do note that the air tangent was launched before the Rockport - so to be correct, the Rockport arm looks like an air tangent ! 8^) |

I only told by the friend that is an Oxford crystal. No photo and no other info up to now. The sales is sure real but no other details at this satge. So I search the web and found that wow......a Rockport look alike. It quickly came to my mind that this could be a well match to my upcoming terminator!
And when it comes to turntable, many high hands friends to ask la! I am waiting for the price and real photo. |

Don’t know anything about the turntable, but if the Airtangent arm is included, then it may be an interesting buy!

To put things in proper perspective, bobui is right to say that high power amps were simply not available when field
coils were used to drive speakers, loudspeakers to be exact, which were used basically for sound enforcement in
public address and theatres where efficiency was paramount.
Now high power amps are everywhere, be they solid state or vacuum tube. High fidelity, in the true sense of the word,
is part of living for many blokes and theatres, almost extinct.
The audio world is indeed quite different now.

Field coil is but a primitive device to provide magnetic drive for the early dynamic loudspeakers
-----------------------------------------------------------
Funny the first item that comes up in my Google search of Field Coil magnet is Lowther America.
----------------------------------------------------------
According to Lowther, Field Coil was there in the first place when Alnico magnet was still miles underground and not yet discovered by the hard working mining labour by accident! The strong magnet was necessay for public address and even home audio because of the wee power triode at the time. You know the 1 watt amp.....!
Englighten me please for there is any real advantage of Field Coil in 21st century.
I have been a fan of Lowther for over 15 years and in short, Lowther cabinets are ugly looking, ancient design, cannot go too loud and narrow bandwidth. I hesitate to recommend to any high hands.
If you agree with my descriptions above on Lowther, please come and listen to my Lowther set up and tell me if I am right! Ah

is there any disadvantage for field coil?
_______________________________
The weight, bulk and shape of the field coil were disadvantages that impelled speaker manufacturers to look for better
alternatives. When developments in magnet result in very efficient varieties like ferrite, alnico and samarium-cobalt etc,
there appears little reason to go back and resort to artifacts.

jaspert,
Your 301 in black looks real sexy
Delicious!
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Thanks Limage. Looks good but a vanity project which has yet to pay off sonically.
Ken,
I bought the black 301 off eBay a while ago from a UK seller and got a local guy to make the veneered CLD plinth. My old cream 301 in my own birch ply plinth
sounded more engaging for some reason.

>Big, wont fit into my family size Lowther back loaded horn cabinet. <
____________________________________________
Funny the first item that comes up in my Google search of Field Coil magnet is Lowther America. At 31 lbs each, those magnets are certainly not small, and they require a power supply capable of supplying at least 20 volts and 3 amps per driver!
>Not for the Rolex <
_____________________________________________
I always thought that all Rolex are anti-magnetic! Maybe I was wrong!

Other than needing a power supply, is there any disadvantage for field coil?
-----------------------------------------------------
Big, wont fit into my family size Lowther back loaded horn cabinet.
Heavy, not that the owner has to carry the weight and walk around the house to get it running! But the heavy kg means even if a cabinet has the room for the huge long magnet, you still cant fix it on the baffle with the 4 tiny screws on the frame. Something will break if not your arms.
Not for the Rolex and the cat: Lucky I only wear an Omega! And I always make sure I took it off everytime when I play around with my Lowther PM7! Speaker picking up your cat! There is always metal content somewhere in the collar!

_______________________________________________________
Correct me if I am wrong, but isn’t field coil able to produce way stronger magnetism than normal magnets? I have seen field coil magnet picking up a whole car in the junk yard, but of course, those field coil magnets were quite big!

Field coil is but a primitive device to provide magnetic drive for the early dynamic loudspeakers. I guess the passion
behind is akin to worshipping the earliest valves.
By the same token, the gramophone that Edison used for demonstration ought to be the paragon of high fidelity perfection.

Jasper - that is also an after market platter - care to share ?
daiwok
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
A guy from a local audio club made a few of these platter+bearing a while back. They didn't sell well so I got the last one for a reasonable price.
The platter is bigger and heavier than stock. Nicely made and same with the bearing. |
