Field coil drivers, the next wave : Yes, brilliant indeed! The time is very right for such an "evolution".
And, we can hypothesize that it might have been so... Had Romy not posted this prediction.
However, in so doing, Romy may have just short ci...

RobertAren't those meant to be driven by 250W SS amps ? Did you chose driver for your midbass already ? I thought that for this range 8" Lowther DX series with its 50Hz Fs and its "lean" sound could compliment your GOTO drivers (16 Ohm version has 3m...

Check out are field coil drivers and the blab it shows pics of the bass drivers as i build them you may fined it fun!! i always like you insight + field coils are easier to build these days that is why most of use do it and they sound nice.http://www...

I'll try to make some comments on Feastrex Sound in this post. It is always difficult for me to isolate the sound of the individual parts I want to analyze. Like in this thread, which has partly evolved into the effect of all pe...

given that you are only really interested in measuring the field strength in one particular size of magnet gap ie that of the S2, is it worth considering making your own as in this link. http://home5.inet.tele.dk/f-hammer/fildcoil/measure.htmOne coil...

I think it best you speak to Ralph directly ,he works with these drivers every day.I do recollect that inthe case of the Supravox ,where there are permanent and field coil versions of the same driver,Ralph told me that there wasn't a huge difference ...

Hi Romy Indeed you sound a little racist, but i think we all have our prejudice. Funny enough, i didnt recognize nor cared, spotted the horn with my eyes, went in and listened.Now, read this carefully: I listened to the system with closed eyes, for ...

[quote user="Dominic"] i thought of it as soft and chalked it up to not being as strong a motor as was needed and begrudgingly accepted that perhaps 'field coil' did not mean 'powerful motor'. I'm starting to think otherwise…[/quote]
Yes, it is exac...

Indeed I am welcoming a newcomer to a horn world. It looks
like a Chinese company that makes me slightly to be withdrawn. So far I did not
see original Chinese production that did not cut corners or did not impersonalize
western product but in bad...

Romy,
No, the DAC was not set at maximum level (for best sound) while Cyrille listening to the system. It was set at normal volume for the whole system. When Cyrille dropped by, I was showing him the Field Coil open baffle speaker system which con...

[quote user="haralanov"] My driver has not even a single trace of tizzing top end. Tizzines is intrinsic feature of ribbon drivers (including RAAL), not of well designed paper drivers. Actually, the heart of my acoustic system is ultra high perf...

Somebody from AA was asking about electromagnet. The subject pup up here from time to time but this time Bruce Edgar uploaded an interesting comment. Bruce is not a typical AA Moron and if he says “inaccurate things” then it is not due to ignoran...

I do not think that you really can trust an answer from someone willing to tell you what to do. Sure, the Klughorn is a great thing, but I have never heard it suitable integrated - which says NOTHING about the horn and driver but a lot about those us...

Listening the argument of the field-coil’s people I note that they constantly stress the demagnetization subject of the driver’s magnet, advocating that with electromagnet “the field coil will always produce the same strength now and 100 years in the...

I really don't get out much any more, just happened to run across this while looking for high-powered SETs:http://www.avguide.com/news/2008/01/23/ces-2008-dick-olsher-investigates-tube-gear-at-ces/4/Look at text down below the Classic Audio speaker p...

Forgot to elaborate the Quad system.It is actually a tri-amp Quad system, below 100Hz is the Supravox 15in Field coil in open baffle, then it's a Stacked Quad ,and about 5Khz there were 5 RTR ESL cell. I did try the 6C33C amp in a single pair Quad by...

Without wishing to open a can of worms....Mine are the 1443 - same as the 1428B save for the field coil voltage. I've finally got round to ins talling some of Cogent's replacement diaphragms to restore them properly. I can't say enough good thing...

The voices, the voices...Just a word of warning, if you do decide to give this a go, remove the diaphragm first and be sure to have exactly the right size screwdriver - that bolt is prone to flaking...Might I suggest that if Macondo has evolved to th...

Hi Romy, Splendid work - much appreciated research this!I know this is totally premature, but if you do find that you prefer the S2 as the flux is increased and hit a current limit for the coil, then you *might* get a flux benefit by using a lower ca...

Allo R,Not to start a pissing contest, but how are they wired (series/parallel?), and with what voltage across them? Something just can't be right; the makers spec is 88db / 2.83V, which is over 1W. Unless it's uniquely smooth room gain with the arra...

Congratulations, Rick. May your new batteries live strong and long. My storage spaces are crammed with wrong, superceded, and experimental hi-fi gear, including many dead SLA batteries I used in series to power a field coil driver. Gotta round those ...

Trying to explore the upper bass channel reaching up to a Victor Sierra 360 Hz horn with an Altec 804 with a 4 uF oilcap, I first used my OB Supravox 215, then a B&C 8" woofer in a large BR originally used with EV 15" (the latter not good) ...

I suppose I have "learned a lot about drivers" and speakers over the years, but age has overtaken my production capabilities, and I am selling my stash of drivers. Included for sale is the Holy Grail of lower mid-range drivers, a particular variant o...

Romy, the main driver in this acoustic system has nothing to do with the funny Lowthers. It is very high class field coil speaker unit made by Oleg Rullit. Take a look:The owner of the system has tried the highest class of the Feastrex line of widera...

yes romy but my english is badThe JBL 2420 alnico sweet sound with my trumpet tactrix not felt the need for a tweeter, but the high was a bit behind. with the field coil at 100 volts sounds almost equal all'alnico but increasing to 130 volts, so that...
