Hi Panos,Romy asked me for a sanity check on your stated performance limits for your SE OPT's. It is good to see someone paying some attention to what is in the Radiotron Designers Handbook for high performance coils. What you are doing, winding five...

[quote user="coops"]I have't heard the driver in the Beta, I am told that there isn't a great deal of difference sonically between the field coil and the alnico magnet versions of the driver. [/quote]
It is most like that people who told...

Very interesting… Earl Geddes just posted his thoughts for the Morons at the AA. I do not know is he was inspired by my post of by the completely foolish nose that the AA’s idiots razed around the Cogent’s Steve and Rich experiments but still – it wa...

Yes, steel chassis can be both good and bad. It likes to conduct magnetic fields, so you have to treat things appropriately. A little spacing under a choke can go a long way. Otherise you have a 120Hz motor. I have another tri...

If the RCA 1443 the same as 1428B but without the field coil then it might be even more interesting than 1428B. As I understand that those prewar driver had phenolic diaphragms that generally shall have tendency to be a bit soft with low order filter...

Hello,A couple of things to correct here - the horn flare is not conical even though the exterior surface gives that impression.Also I don't believe Jeffrey has any affiliation with weiss or other industry types at all - in fact, from what I've seen ...

What the sonic impact will be? I clearly have no idea. I was slightly desponded and warned that my excremental S2 with electromagnet did not have the “sonic impact” that I find useful.Regardong the Quartopuss... Chris, you're confused because t...

Very interesting application Romy, I really like the adjustment system that you built in. I have some EV tweeters in the shop, never even listened to them. Steve Schell and I haven't gotten to the point of trying tweeters in our field coil system yet...

Romy's prediction of field-coil speakers as the next move for the industry may already have started in small segment in Japanese market. There's Feastrex and Shindo, then G.I.P Laboratry who specializes in W.E. clones and seems to be gaining a ...

[quote user="guy sergeant"] I have looked at the Feastrex website. The picture you show is of one of their permanent magnet drivers. This uses their Naturflux magnetic circuit. Mr Akiyama's quote also refers to one of these permanent magnet drivers s...

Romy I have read on this forum that you are not particularly keen on the very low output AN Japan ( and Uk ) cartridges, may I ask the nature of your experience with them , have you tried the field coil versions? Thanks Keith....

Ralph uses a field coil version of the Supravox driver ,as an option in the Cessaro 'Betas', and has been experimenting with the GIP drivers.To my knowledge the drivers aren't modified,( I would have to ask Ralph to confirm ) but He does build the po...

No, I wasn't heard they big speakers but ever if I had I would advise you to really do it by yourself than consider opinions of others. Unless, of course, you really know the person and the person taste.You can contact them directly, they are respons...

Move over Feastrex, here comes another OCD Lowther-alike, the Voxative something-or-other. When you visit the V site via the link be sure to follow up on the wood-coned, field coil, nominal 8" FR driver that seems to be the only motor in the cabinet...

Romy, I presume this is with the new production diaphragms? Just wondering if the old ones might restore some of the youthfullness which was diminshed by the field coil?...

Hi Romy,
When we spoke at CES, you mentioned that your experience with field coil drivers only extended to cone types. So I assume that you have never heard any field coil compression drivers. That would include the WE 555, 594, RCA 1428, Lansing, e...

Hello Guy,Please excuse the rapid fire response, bit short of time today.1)Your comments about the Io cart are most interesting; clearly it ain't about saturation. Here's another idea: if the domains in the magnetic material limit resolution (leading...

Yes, I think we are all agreed that flux demodulation is not the issue here, and that simulating different permanent magnet materials statically may be interesting but is unlikely to be revolutionary. But if FCs have a unique advantage it has to be t...

I was pointed out to Steve Guttenberg’s video “Meet Joe, and

Well, someone named lNHUMANE left this comment at YouTube (he is most probably right):"That WE16B speaker is set up for stereo, not mono. There are two sets of drivers and two horns with a common mouth. Of course, stereo did not exist when it was in...

Ralph and Thomas are friends there would have been no price premium for the field coil option, they would have listened to both versions of the driver and made a decision on sound alone, I take your point though of an old technology resur...
