I sent Ken the LE-14Hs from my 250Tis and he did an outstanding job— replacing surrounds and spiders, gap cleaning, and filter replacement. They should last the rest of my lifetime. I wouldn’t think...

I can echo Grumpy’s experience, his work on my LE-14H woofers was superb. It did take several months for him to complete but the end result was worth the wait, IMHO. It may not be quick but it will...

Yep I see now the 1962 date, it was not obvious on my iPhone. Bud was an interesting character on the audio scene. I did enjoy my IMF Monitor speakers from the late 70s although I don’t believe he...

Fried was supposed to have been a pretty good salesman; do you think the fact that he was importing IMF speakers back then that used KEF B139s had something to do with the “death” of paper cones? 😊

I didn’t see when that was written but I think it was the 1960s; Fried has been dead for years. Was probably news back then I suppose.

And I've spent all this time and money getting 33 1/3 Hz AC service into my house just to use it!

Damn, its currently unavailable due to parts shortage! :frantic:

David, you are correct, a cap value of 3uF is too low for this application; a 10uF cap should do and I have one in my parts junk box. I have not seen any published spec on the impedance of the driver...

Thanks for the information David, very informative. In looking at the o-ring and metal protective mesh screen, it appears it might be easy to mar the metal finish of the driver or the screen by...

Ah, now I see what you are saying, thanks for the picture. In fact I think I have some of that material, I saved it for packing purposes. Thanks just the same for offering to send me some, I've...

Interesting, egg crate type foam-- isn't that a kind of styrofoam? After outfitting your tweeters with that material, what difference did you notice, if any, in the sound of the tweeters?

Just...

I seem to recall having read that thread before but thanks for bringing it to my attention, it was instructive to read it again. I guess my main concern is taking the tweeter apart, my eyes (and...

I've had my 250Ti since 2011 and they have given me very little trouble since then thanks in no small part to advice obtained here.

But now things have changed. I also own a pair of Martin Logan...

I used Uship.com and selected a moving company to ship a pair of Infinity RS-4.5s from Washington State to Northern Virginia. The moving company was not the lowest bidder but I felt they had the best...

Postscript: After turning on the system one evening this past week, I was stunned to hear that one of my replacement 044ti tweeters was apparently not working, only a few days after the successful...

Thanks and your help is much appreciated! Neither the spares nor the 250ti are going anywhere, at least not without me! They are "permanent" members of the family. :)

Success! Drilling went easy. I took the advice from Junior JBL and screwed them down to plywood and drilled the holes out one at a time. I used Saran wrap to cover the driver screen at all times to...

It keeps coming back to me that I should have never let my father's drill press go in the estate sale! The old hand drill will have to do.

Sound reasoning, I'll drill them out. Any problem with drilling out the threaded holes on the 044ti? It appears to be fairly soft metal but I would lean towards using my AC powered Makita versus a...

Yep I have read previous those threads but I'd like to try these newer (by a few years according to the dates on the back of the drivers) 044ti before trying the other options discussed- frankly,...

My (presumably original) 044ti in my 250tis are beginning to sound a bit hissy and edgy. A few years ago, I bought a beautiful pair of threaded 044ti off the web before I knew there was a difference....

Still using the Parasound HCA-3500 (350 watts per channel) when driving my 250Tis either full range or when used with the Kinergetics SW-800 subs. I have tried Hafler 9505 singly or a pair in mono...

Enjoy the ride, these are excellent speakers. Feed them a good signal and they will reward you with fine sound. It's been more than a year since I bought mine and I have greatly enjoyed every minute....

With tube gear, the first suspect is the tubes themselves (there appear to be 11 tubes including the "magic eye" tuning tube). You should check the tubes with a tube checker; if you don't have one...

The front plane of each 250Ti is 5 feet from the wall behind it and the center of each woofer is about 3 feet from the side wall. The room is narrow so I don't have a lot of options with side wall...
