IMF owners thread!

Took out the crossover today. Burn marks under the 15 ohm resistor (although it still tests good). Caps are within spec and ESR using my meters, but I'm going to replace them all in any case.

I would change the resistor as well. I am going to use the Ohmite Audio Gold that they sell at partsconexion.com

Oh yeah. If it wasn't clear, the resistors will be replaced too, with higher wattage units that should dissipate the heat better.
 
Day Dreaming post here. I've picked up some really good 2 way bookshelves since my buying binge hit, and trying to think of ways to incorporate them with my IMF's. I'd been thinking of just disconnecting my 2 HF drivers and perhaps the mid range, or get fancy and add switches. Or is this overworking it? I don't really want to add more gear, i.e. a cross over, but that might be the most effective way. And I'm uncertain what just unhooking will do to impedance and if there are unintended consequences. I've already played with adding an ESS HEIL on top of my IMF's and thise seems to work well enough, I just lower the HF dial on the back. The other speakers I want to try are Chapman 250's and Sequerra Met 7. I'm thinking Wilson Watt/Puppy here.
 
Hi, seems IMF gain value if in great condition,this reflect on Ebay. Wow the TLS 80 MkII look in great shape,rare HPCM too and a nice Als 40 MkII and this old Tls 80 the veneer of the cabinet have have seen better day's.

Yeah, they're certainly rising in value from when I first bought my TLS 50 IIs. Looks like the secret is finally out on these.
 
Hi,yes it will be good for all IMF owner"s, when selling, plus give more credit to the brand. That's the problem of old speakers when the company's have stop manufacturing, so not well know by the younger generation.
 
Hi everyone,

Some very exciting news has surfaced. Jerry Bloomfield of Falcon Acoustics has revived the IMF brand! This means new speakers produced under the IMF name. At the latest Munich show, the "DM-100" was showcased, which essentially is a two-way small speaker. They are retaining the use of the original logo as well as using American Walnut for the veneer. Jerry's intention is to continue the company in John Wright's vision.

As well, they debuted new drive units - a revised version of the B110 and B139 Kef drive units. The B139 is an uprated model able to handle 150 watts of power, which is what owners have been looking for since their debut in the 60s. The new B110 is a paper cone version, not bextrene, so it will be a different sounding driver but will draw similarities to the original B110. My understanding is this drive unit was developed specifically to be used in IMF speakers.

This means that there could be upgrade kits offered to existing owners. This is fantastic because the very last point of restoration to bring these loudspeakers back to their former glory is by restoring the drive units! Meaning, the opportunity to hear IMF speakers as they were heard originally is no longer a dream, but a distant reality.

I don't have anymore information, but as I find out more, I'll let you all know.

Thanks for that article Jim, would be fun to try that swap out. Also noted on that pay site how many sets, some super compacts as well, but are they really that rare?
 
Can someone help me source a replacement mid for a set of IMF super compacts. The last owner had stored the midrange facing down and the spider has now stretched to the point of no return. If anyone can help i would be much appreciated?

If you are looking for a new driver to buy, this is your best bet: http://www.falconacoustics.co.uk/drive-units-1/imf/monacor-msh-115-imf-midrange.html

Otherwise, you are looking for either an ELAC 4/EM101 or a 4/200. The difference being the 4/200 has a polymer-developed cone (not sure of the exact material) and the 4/EM101 is a paper cone. Either will work fine.
 
hi, just look at ebay some 4 inchs mids for sale, on the boxe said IMF, but I don't know if are original, good to verify or contact the selller.
 
I´m joining the club with a pair of RSPM mkIV that I´m in love with since about 5 days. What a spectacular set of speakers!!!! I had quite a few classic speakers in my collection but these are probably the best.
First of all, they seem to sound very proper within the entire spectrum, beginning with extremely deep, colorful and well defined bass, through a very transparent, coherent, musical and involving midrange, to smooth and silky highs. I was expecting they would sound slow, but hell no, they are actually very fast and transparent, whatever kind of music you feed them with, they just seem to reproduce it in a very distinctive way. The soundstage is just huge but it´s NOT that kind of a "wall of sound" soundstage that´s spread over the entire room as we often hear from horns or flat panel speakers - the IMF seem to build a natural size of soundstage, at least for my ears.
I power them up with a pair of german studio amps from Klein Hummel and with Lampizator Big7 DAC with tube output stage. Heaven, I´m in heaven... :-)
 
Hi,sorry no I don't, me I have some IMF Mk I EMI spares but not the Mk II new version, couple of weeks ago a seller on Ebay was selling a pair for $ 129.00 IIRC.
 
I'm after the EM101s for the super compacts?

HI, they have paper cone, Falcon suppose to ressucitate IMF brand, they should make new mids, but when it will be in production? it will take time.
