IMF owners thread!

Falcon sell cover for the Ls3/5a not exactly the same as celestion but similar.I would like to try but I have to be sure the diameter of the dome is close to the celestion HF2000 and Ask Gerry for the exact dimension of is cover.

Both are "19mm" domes so I imagine they're quite close in size. I'm tempted to give it a go, I just wish there was an aftermarket option that wasn't $50, it feels wrong to spend more on a couple little perforated metal covers than I'm spending on recapping the crossovers! Maybe I'll put those on the wish-list for the future when I redo the backs of the cabs.
 
Hi Ross, the only way to get the original is buying spares hf 2000 expensive min. $100 each, I have seen one time someone was selling one cover but was asking $25-30 for + shipping. Very hard to find these one. Esthetic very expensive!
 
So here's an obscure question, what type of glue was used to adhere the laminate? Some of the trim around the base is getting pretty flappy at the edges and I want to stick it back down. PVA? contact cement? Something else?
 
Cool, solvent based contact cement it is!
A couple of the pieces around the base are broken/missing, I'm going to order some Formica samples and see if I can match the color (or at least get close).
I ordered the complete Improved recap kit from Falcon today, we'll see how fast "air mail" is going these days.
 
Hi try to use the WBT soldering with 4% of silver, it make a better contact.You don't need much.I have change the size wire of the woofer with Monster XP + the two posts with Cardas and change the wire from the crossover to the cardas.I find you have more control over the woofer and overall it sound better to my ears.
 
Hi Ross, please can you take a close up of reference standard plate with the dimension because I contact a guy on ebay who can reproduce any speaker logo, so I like him to make some IMF , improved, reference standard plates. So the one who have MK 3 speakers can have it if they want. This guy after can produce these logo any time at a good price.Best regards Yvan.
 
Hi, very happy for you! Listen to them and If you want to upgrade more you can insulate the midranges tube inside because it's well known at high volume the bass sound can go through the tube and mix with the mids.That's is why on the RSPM Mk7 move the mids on top to eliminate the problem. We can't not do that so if you look on page 44 I install 1/2 " filter carbon pad to really help to insulate the tube. The advantage of carbon pad, because of its cavities it do not reduce the tube,they say it ad to the inside dimension.It's a good sound barrier and some sound ingeneers use it too insulate studio or private music room. Kef 107 mids have some carbon in theirs midranges section.Best regards,Yvan.
 
Really in desperate need of some help! After many years of looking, a couple months back, I was able to purchase a pair of RSPM MKIV's from the original owners daughter. A friend of mine and I have been working on refurbishing them, wanting them to have the opportunity to perform optimally. We have replaced all the caps and also, all the drivers except the non replaceable Celestion HF1300 tweeters. We were about to finish things up, and listen to the speakers when we became aware of an unknown tragedy. Now, unfortunately, I am afraid I may have a real disaster on my hands. My friend, who is an electrical engineer and serious audio enthusiast was helping me with refurbishing the
RSPM's. We were doing the work at his home, as he has a large workshop at the back of his garage, and there really is no suitable space at my home. As I had noted previously, we swapped out all of the caps, and then removed the old speakers in preparation for replacing them with the new drivers that I had received from Falcon. We temporarily placed all of the old drivers in a box, as we were working on refurbishing some areas of the cabinet front.
My friends wife happened to be putting out the trash this past Monday, and saw that we had completely cleaned up the workshop, except for one box on the floor. It was the box we had placed all of the speakers we had removed from the IMF's in. She made the mistake of thinking we had somehow forgotten to put that out with the rest of the weeks trash, as it looked like old, junk speakers, and her husband had told her that we put all new speakers in. She took it out to the trash, waiting to be picked up, and set the box in the pile. Later that day it was picked up and taken away. We did not realize what happened until a few days late when my friend went out to his workshop to get the super tweeters from the box we had saved them in. He then talked to his wife, and discovered what had happened. Obviously, none of the other speakers matter, but I was told there were no available replacements for the Celestion tweeters. I was on the phone to the trash removal company that day, but they have informed me that anything that was picked up, and taken to their dumping area several days previously, would now have been bulldozed and covered over with tons of additional trash picked up on Tuesday and Wednesday and could not possibly be found.

Besides the effort of looking for a good pair of these for so many years, having over $2000.00 in these speakers between the original purchase, and the capacitator kit, and drivers, I'm terribly afraid that I will have nothing more than two large doorstops thanks to what happened. I was in touch with Jerry from Falcon, who thought he could come up with a solution, but, I'm concerned that something must have happened there. After never failing to respond to my e-mails during the process, he has not responded to any of the messages I've sent him since early March.

Any thoughts on what I can possibly do here would be greatly appreciated. I wanted so badly to have these speakers up and running.

Hi, please do you or your friend know if they are 4 ohm, 8 ohm or 15 ohm? If not, maybe Jerry from Falcon ?Yvan.

They would be whatever was used with the RSPM MK IV's. And, as I noted above, something appears to have happened a tFalcon. Jerry has not replied to numerous e-mails in nearly two months.
