IMF owners thread!

Good evening. I'm from Poland. I currently own IMF TLS 80 speakers. However, I would like to upgrade them to RSPM. Is anyone here planning to sell IMF RSPM IV Improved speakers in their original condition?

Pretty hard to find those as they were produced in very limited numbers towards the back end of IMF production. There are two variants of the "Improved" one with Celestion top end and the next variant with full Elac contingent of drivers.
 
Hello all, I just joined the IMF club with the TLS80 MKII.
I have a question regarding capacitor values, specifically tinkering with the value of the 60... I ordered the kit from Falcon to change out those Elcaps. My crossovers have one each of the following...100uF, 60uF, 6uF, 12uF, 4uF.
However the kit I received has an 80uF instead of the 60. Plus a pair of extra 4uF. I just reached out to Falcon to see what gives and have to wait to see what they say. Meanwhile I put in the caps in the speaker that was having a problem (used the 80uF to replace the 60) It brought my midrange back to life which was basically dead before. I think it sounds fine. But can it do any harm? What might I expect this change to do? Curious if there is any such change recommended as a mod or something like that.
 
Hi again. I bought imf als 40 mk2, photos attached. They are 100% original. My question is which version is it? The crossover has 2 capacitors 4uf 50v and gives 60uf 50v. Photos are attached.

Hello, is anybody here able to help? I have a pair of TLS80 that needs rewiring, but I have no idea which wires go where on the crossover? Anyone familiar with these?

Post #11 (couldn’t get the direct link to work)

The crossover in this schematic looks to be a match to the ones in your photo. there’s a PDF link in that thread, adding screen caps in case the linked site goes down in the future

Actually I just had a good look and mine look completely different? Are there a few different crossovers for this model speaker?
 
@Vroomy ah shoot you’re right, that’s what I get for not doing a side-by-side comparison

The thread I linked to has other crossover circuits and while I didn’t see another one with such a specific wiring connection color key I don’t go through every post on every page.

Right now a CJ ss 120 watt, but have used a Bryston 4B and a Coda 1.5 150wpc. I'd really love to find a pair in white! mine are walnut grain formica. But I rotate them with a pair of Tyler Acoustics D1xSE, and a pair of Monoliths. Guess which ones have better low end? And the Tylers have Eight 8" $400 woofers!
 
Hi welcome to this forum, I own myself a pair of MK III improved, can you take à picture of your X-over by removing the woofer, I'd like to compare yours with mine, Yvan.
 
Hi, the prof.MKIII have an update on the X-over (improved) and after that later they call Reference standard IMF and should be the same as mine. That's why if you remove the woofer we can see what model you have.best regards Yvan.
 
Hi, the prof. MKIII have in upgrade when IMF was selling them, X-over was upgrade and à plate "improved" was add on the front on top of IMF logo, later à plate "référence standard" on top of IMF logo instead of"Improved". I don't know.what model you have, but if you remove the woofer we can see the X-over. The sifference between not improved and improved is very easy to modify, best regards, Yvan.
