FRIED MODEL R Inductor Value

luvmusik

HOORAY !...ELECTRICITY !
For the FRIED MODEL R SERIES II speaker, does anyone know the INDUCTOR VALUES for the crossovers, or can refer me to someone who knows ? Does anyone have Series II and can MEASURE the inductor values of the crossovers ? Any help is greatly appreciated, Thank You !

Not sure if the RII used the Kef. Which driver's inductor? I am quite familiar with all the C and O models. Can you post a picture of the drivers and the crossover?

BITD Fried had no markings of the value of the components used in his crossovers.
Some of the drivers had the Fried name on the back of them, the link illustrates this.

Thanks for info and great link, also from PA here in Macungie, not far from where Fried calls home (hotbed of enthusiasts around here). I've been stuck on finding this crossover for sometime, it is much different than then Fried Model R Series I. What I've found is that Bud modified a KEF Concerto crossover for use in the newer Model R Series II which achieved the frequency cross point of inflection lower at 200 Hz woofer to mid , down from older different one used in series I that crossed at 375 Hz. It also allowed greater dynamics, and better power handling, with higher playback volume and better realism sonically, per Bud "opening up" the music greatly. A kit was available for this modification , for owners to upgrade, along with a later tweeter circuit mod. I wish I had a photo of series II crossover, I can't find any vintage Series II crossovers for sale. Surprised at xover pt, didn't know the woofers & mids could handle that 200 Hz point to cross at...KEF B-139(SP-1044) woofer & B-110(SP-1003) mid & T-27(SP-1032) tweeter. More than this is pretty much over my head (newbie) but I may be able to have crossovers constructed from Falcon who have schematics of the series II crossover and tweeter circuit mod; the crossover could be made they say if the inductance values were measured on someone's series II crossovers (the only missing piece of the puzzle, 99.9 % there), or if one was available physically to mail to them (series II crossover),they say they can then measure and make a replica pair. Pretty much over my head, but trying to learn !
 
I see the inductor values were not given. The models using the Kef units were being phased out when I purchased my first kit in 79.

He moved the business from Philly to Norristown in early 90's and aquired a new partner.

The business was sold in the late 90's and resold again a few years before his death.
The website of the company is still on the interent but remains dormant.

The owners of the company would not be of any help with the old designs.

I have been using a wide variety of his designs over the years.

Out of curiosity about how many Fried enthusiats are in your area?
I wonder what some of the models they have might be.

Are any of them DIY builders like myself? I am not far from you being in Montgomery County LOL.


I have found only a few AK members that know of the former company.
 
"I knew Bud Fried. Bud Fried was a friend of mine. Senator, you are no Bud Fried."

But seriously, I sold a ton of IMFs, and we never called him "Bud" (I was an 18 year old punk working my way through Pitt, he was a bigshot Philly lawyer in a thousand dollar suit with his initials on the greatest speakers I'd ever heard) but he loved our little store and came by pretty regularly. He had an incredible ear, but he was no scientist, designer or engineer. He was Jewish lawyer/audiophile who made some really smart moves back then. He knew America was ready for something better than Advent/JBL/EV/EPI etc. and he made it happen. Irving was awesome. He liked me. He comped me a pair of Supercompacts.

Montgomery county is near Lehigh county; and the way I remember the IMF/Fried start around here went back into early 1970's in Emmaus, PA (Lehigh County) outside of Allentown. A shop called "Sound Advice" there owned by 2 great guys , (I think as a hobby), sold IMF, hi-end Sony & Yamaha, nice turntables, reels, everything for an average size shop, lotsa great brand names I can't remember. The guys were so cool to let us all listen to our favs there...my 1st encounter and lasting impression of RSPM started as thus. Later I think they sold the Fried line there, but I forget that far back, because I don't recall any other shop carrying Fried & they were selling right around here (possibly also a shop called Gordon's Sound Studio, Allentown; otherwise, not much else was around except HI Fi House in Whitehall and an awesome Lafayette Radio & Electronics Allentown parts store !). Three of my buds from back then bought either Super Compacts or later Model R's. Always wondered where the 2 owners went & wanted to thank them for the early audio demos. My 3 buds moved to Harrisburg, Narberth & Doylestown; we lost touch long ago. The 2 owners of the shop would know much more about area fans, if they're around; and like we were saying, because the suburban Philly area is "home" for Fried, they easily distributed around here. I only got to speak to Bud once a few years before he passed on, I addressed him as Mr. Fried (Bud is so quicker to type); he was really nice as we spoke over the phone; he said his listening system was the top-line Fried offering at the time, I forget which flagship model was made right before he left us. It's about all I can remember, currently everyone has been out of touch, we all moved back & forth around the U.S. But, the tradition is still carrying on, torch is passing and these speakers, IMF and Fried are still vibrantly heard today!
 
I would suggest ;) and don't ask about the source.


For a B139 @ 200Hz 7mH, 3.5mH used elsewhwere.

For the B110 1mH, 4mH, the circuit seems to be a cut-down version of something else

and for the T27 in a "cut down aB section @3500Hz" 0.3mH - Rdc 0.55 ohm is normally used.

You could buy a cheap capacitor/inductance meter and measure the value of that inductor lift one leg of the inductor and measure the mh value.

Again. I know this a real late retort. But I totally believe your story. He had a gift. And he went with it! And it worked.

I tried measuring some inductors I have with known values, the results are really inconsistent, inductors are complex things to measure and done at certain frequencies. It's a good idea but I wouldn't trust the readings.

And I just saw the date of the post I was replying too. LOL.
